v1.6.0 (unreleased)
-------------------

Added
~~~~~

- New `tabs.new_position.stacking` setting which controls whether new tabs
  opened from a page should stack on each other or not.
- New `completion.open_categories` setting which allows to configure which
  categories are shown in the `:open` completion, and how they are ordered.
- New config manipulation commands:
  * `:config-dict-add` and `:config-list-add` to a new element to a dict/list
    setting.
  * `:config-dict-remove` and `:config-list-remove` to remove an element from a
    dict/list setting.
- New `hints.selectors` setting which allows to configure what CSS selectors
  are used for hints, and also allows adding custom hint groups.
- New `:yank markdown` feature which yanks the current URL and title in
  markdown format.

Changed
~~~~~~~

- `:q` now closes current window instead of quitting qutebrowser completely
  (`:close`), while `:qa` quits (`:quit`). The behavior of `:wq` remains
  unchanged (`:quit --save`), as closing a window while saving the session
  doesn't make sense.
- Completion highlighting is now done differently (using `QSyntaxHighlighter`),
  which should fix some highlighting corner-cases.
- The `QtColor` config type now also understands colors like `rgb(...)`.
- `:yank` now has a `--quiet` option which causes it to not display a message.
- The `:open` completion now also shows search engines by default.
- The `content.host_blocking.enabled` setting now supports URL patterns, so the
  adblocker can be disabled on a given page.
- Elements with a `tabindex` attribute now also get hints by default.
- Various small performance improvements for hints and the completion.
- The Wayland check for QtWebEngine is now disabled on Qt >= 5.11.2, as those
  versions should work without any issues.

Fixed
~~~~~

- Invalid world IDs now get rejected for `:jseval` and GreaseMonkey scripts.
- When websites suggest download filenames with invalid characters, those are
  now correctly replaced.
- Invalid hint length calculation in certain rare cases.
- Dragging tabs in the tab bar (which was broken in v1.5.0)
- Using Shift-Home in command mode now works properly.
- Workaround for a Qt bug which prevented
  `content.cookies.accept = no-3rdparty` from working properly on some pages
  like GMail. However, the default for `content.cookies.accept` is still `all`
  to be in line with what other browsers do.
- `:navigate` not incrementing in anchors or queries or anchors.
- Crash when trying to use a proxy requiring authentication with QtWebKit.
- Slashes in search terms are now percent-escaped.

v1.5.2
------

Changed
~~~~~~~

- The `content.cookies.accept` setting is now set to `all` instead of
  `no-3rdparty` by default, as `no-3rdparty` breaks various pages such as
  GMail.

v1.5.1
------

Fixed
~~~~~

- Flickering when opening/closing tabs (as soon as more than 10 are open) on
  some pages.
- PDF.js is now bundled again with the macOS/Windows release.
- PDF.js is now searched in the correct path (if not installed system-wide)
  instead of hardcoding `~/.local/share/qutebrowser`.
- Improved logging for PDF.js resources which fail to load.
- Crash when closing a tab after doing a search.
- Tabs appearing when hidden after e.g. closing tabs.

v1.5.0
------

Added
~~~~~

- Rewritten PDF.js support:
  * PDF.js support and the `content.pdfjs` setting are now also available with
    QtWebEngine.
  * Opening a PDF file now doesn't start a second request anymore.
  * Opening PDFs on https:// sites now works properly.
  * New `--pdfjs` flag for `prompt-open-download`, so PDFs can be opened in
    PDF.js with `<Ctrl-P>` in the download prompt.
- New settings:
  * `content.mouse_lock` to handle HTML5 pointer locking.
  * `completion.web_history.exclude` which hides a list of URL patterns from
    the completion.
  * `qt.process_model` which can be used to change Chromium's process model.
  * `qt.low_end_device_mode` which turns on Chromium's low-end device mode.
    This mode uses less RAM, but the expense of performance.
  * `content.webrtc_ip_handling_policy`, which allows more
    fine-grained/restrictive control about which IPs are exposed via WebRTC.
  * `tabs.max_width` which allows to have a more "normal" look for tabs.
  * `content.mute` which allows to mute pages (or all tabs) by default.
- Running qutebrowser with QtWebKit or Qt < 5.9 now shows a warning (only
  once), as support for those is going to be removed in a future release.
- New t[iI][hHu] default bindings (similar to `tsh` etc.) to toggle images.
- The qute-pass userscript now has optional OTP support.
- When `:spawn --userscript` is called with a count, that count is now
  passed to userscripts as `$QUTE_COUNT`.

Changed
~~~~~~~

- Windows and macOS releases now bundle Python 3.7, PyQt 5.11.3 and Qt 5.11.2.
  QtWebEngine includes security fixes up to Chromium 68.0.3440.75 and
  http://code.qt.io/cgit/qt/qtwebengine.git/tree/dist/changes-5.11.2/?h=v5.11.2[various other fixes].
- Various performance improvements when many tabs are opened.
- The `content.headers.referer` setting now works on QtWebEngine.
- The `:repeat` command now takes a count which is multiplied with the given
  "times" argument.
- The default keybinding to leave passthrough mode was changed from `<Ctrl-V>`
  to `<Shift-Escape>`, which makes pasting from the clipboard easier in
  passthrough mode and is also unlikely to conflict with webpage bindings.
- The `app_id` is now set to `qutebrowser` for Wayland.
- `Command` or `Cmd` can now be used (instead of `Meta`) to map the Command key
  on macOS.
- Using `:set option` now shows the value of the setting (like `:set option?`
  already did).
- The `completion.web_history_max_items` setting got renamed to
  `completion.web_history.max_items`.
- The Makefile shipped with qutebrowser now supports overriding variables
  `DATADIR` and `MANDIR`.
- Regenerating completion history now shows a progress dialog.
- The `content.autoplay` setting now supports URL patterns on Qt >= 5.11.
- The `content.host_blocking.whitelist` setting now takes a list of URL
  patterns instead of globs.
- In passthrough mode, Ctrl + Mousewheel now also gets passed through to the
  page instead of zooming.
- Editing text in an external editor now simulates a JS "input" event, which
  improves compatibility with websites reacting via JS to input.
- The `qute://settings` page is now properly sorted on Python 3.5.
- `:zoom`, `:zoom-in` and `:zoom-out` now have a `--quiet` switch which causes
  them to not display a message.
- The `scrolling.bar` setting now takes three values instead of being a
  boolean: `always`, `never`, and `when-searching` (which only displays it
  while a search is active).
- '@@' now repeats the last run macro.
- The `content.host_blocking.lists` setting now accepts a `file://` URL to a
  directory, and reads all files in that directory.
- The `:tab-give` and `:tab-take` command now have a new flag `--keep` which
  causes them to keep the old tab around.
- `:navigate` now clears the URL query.

Fixed
~~~~~

- `qute://` pages now work properly on Qt 5.11.2
- Error when passing a substring with spaces to `:tab-take`.
- Greasemonkey scripts which start with an UTF-8 BOM are now handled correctly.
- When no documentation has been generated, the plaintext documentation now can
  be shown for more files such as `qute://help/userscripts.html`.
- Crash when doing initial run on Wayland without XWayland.
- Crash when trying to load an empty session file.
- `:hint` with an invalid `--mode=` value now shows a proper error.
- Rare crash on Qt 5.11.2 when clicking on `<select>` elements.
- Rare crash related to the completion.

Removed
~~~~~~~

- Support for importing pre-v1.0.0 history files has been removed.
- The `content.webrtc_public_interfaces_only` setting has been removed and
  replaced by `content.webrtc_ip_handling_policy`.

v1.4.2
------

Changed
~~~~~~~

- The `content.xss_auditing` setting is now enabled by default, to mirror
  Chromium's rather than Qt's default behavior.
- Long URLs in the statusbar are now elided at the end rather than in the
  middle, to make sure the hostname is completely visible whenever possible.

Fixed
~~~~~

- Crash in Qt 5.7.1 when a website uses `window.print()`.
- The workaround for Nouveau graphic drivers now works properly again.
- Crash when using `:follow-selected` with a link which is outside of the view.
- Workaround for windows not showing as urgent with some window managers
  (like i3).
- Crash when opening URLs with some unicode characters (IDNA 2008). Those URLs
  still won't open though, due to missing support in Qt.
- Crash when a download directory which can't be created is configured.
- Crash in the `importer.py` script when importing Chrome bookmarks from newer Chrome versions.
- The `content.webrtc_public_interfaces_only` option didn't work on Qt 5.11 previously (it now does).
  Note it still does not work on Qt 5.10 (due to a Qt bug) and Qt < 5.9.2.
- Repeated escaping of entries in `qute://log` when refreshing page.
- The host blocker doesn't block 0.0.0.0 anymore.
- Crash when using :// as URL pattern.
- The `:buffer` completion now sorts tabs with indices >= 10 correctly again.

v1.4.1
------

~~~~~~~~

- CVE-2018-10895: Fix CSRF issue on the qute://settings page, leading to
  possible arbitrary code execution. See the related GitHub issue for details:
  https://github.com/qutebrowser/qutebrowser/issues/4060

Fixed
~~~~~

- Rare crash when an error occurs in downloads.
- Newlines are now stripped from the :version pastebin URL.
- There's a new `mkvenv-pypi-old` environment in `tox.ini` which installs an
  older Qt, which is needed on Ubuntu 16.04.
- Worked around a Qt issue which redirects to a `chrome-error://` page when
  trying to use U2F.
- The `link_pyqt.py` script now works correctly with PyQt 5.11.
- The Windows installer now uninstalls the old version before installing the
  new one, fixing issues with qutebrowser not starting after installing v1.4.0
  over v1.3.3.

------

Added
~~~~~

  accidentally quitting the crash reporter when pressing escape.
- New `qute-lastpass` userscript which uses the LastPass CLI to fill passwords.
- The Makefile now installs a `/usr/share/metainfo/qutebrowser.appdata.xml` file.
- QtWebEngine: Support for printing from webpages via `window.print`.

    `navigator.webkitPersistentStorage.requestQuota` with a new
    `content.persistent_storage` setting (requires Qt 5.11).
    This setting also supports URL patterns.
  * Support for registering custom protocol handlers via
    `navigator.registerProtocolHandler` with a new
    `content.register_protocol_handler` setting (requires Qt 5.11).

- Deleting history items via `:history-clear` or `:completion-item-del` now
  also removes that URL from QtWebEngine's visited links.
- There's now completion for commands taking a variable count of arguments
  (like `:config-cycle`).
- QtWebEngine: On Qt 5.11.1, no reloads are needed anymore when switching
  between pages with changed settings (e.g. `content.javascript.enabled`).
- The `qt.force_software_rendering` setting changed from a boolean to taking
  different values (`software-opengl`, `qt-quick` and `chromium`) for different
  kinds of software rendering workarounds.
- On Qt 5.11, using wayland with QtWebEngine is now possible when using
  software rendering.
- GreaseMonkey scripts now get their own global scope (based on the page's
  one), which allows scripts like OneeChan to work.
- Rapid hinting is now supported with the `yank` and `yank-primary` targets,
  copying newline-separated links.
- QtWebEngine: On Qt 5.11, the developer tools (inspector) can now be used
  securely and without requiring the `--enable-webengine-inspector` option.
- The `<Enter>` key (`:follow-selected`) now follows the currently focused
  element if there's no selection.
- The `--logfilter` argument now can be prepended with an exclamation mark
  (e.g. `--logfilter '!init,destroy'`) to invert the filter.
- `:view-source` now has a `--pygments` flag which uses the "old" way of
  rendering sources even with QtWebEngine.
- Improved error messages when a setting needs a newer Qt version.
- QtWebEngine: Various improvements to make the cursor more visible in caret
  browsing.
- When a prompt is opened in insert/passthrough mode, the mode is restored
  after closing the prompt.
- On Qt 5.10 or newer, dictionaries are now read from the qutebrowser data
  directory (e.g. `~/.local/share/qutebrowser`) instead of `/usr/share/qt`.
  Existing dictionaries are copied over.
- If an error while parsing `~/.netrc` occurs, the cause of the error is now
  logged.
- On Qt 5.9 or newer, certificate errors now show Chromium's detailed error
  page.
- Greasemonkey scripts now support a "@qute-js-world" tag to run them in a
  different JavaScript context.

Fixed
~~~~~

- Various subtle keyboard focus issues.
- The security fix in v1.3.3 caused URLs with ampersands
  (`www.example.com?one=1&two=2`) to send the wrong arguments when clicked on
  the `qute://history` page.
- Crash when opening a PDF page with PDF.js enabled (on QtWebKit), but no
  PDF.js installed.
- Crash when closing a tab shortly after opening it.

Removed
~~~~~~~

- No prebuilt binaries for 32-bit Windows are supplied anymore. This is due to
  Qt removing QtWebEngine support for those upstream. It might be possible to
  distribute 32-bit binaries again with Qt 5.12 in December, but that will only
  happen if it turns out enough people actually need 32-bit support.
- `:tab-detach` which has been deprecated in v1.1.0 has been removed.
- The `content.developer_extras` setting got removed. On QtWebKit, developer
  extras are now automatically enabled when opening the inspector.

v1.3.3
------

Security
~~~~~~~~

- An XSS vulnerability on the `qute://history` page allowed websites to inject
  HTML into the page via a crafted title tag. This could allow them to steal
  your browsing history. If you're currently unable to upgrade, avoid using
  `:history`. A CVE request for this issue is pending, see
  https://github.com/qutebrowser/qutebrowser/issues/4011[#4011] for updates.

Fixed
~~~~~

- Crash in a workaround for a Qt 5.11 bug in rare circumstances.
- Workaround for a Qt bug which preserves searches between page loads.
- In v1.3.2 a dependency on the `PyQt5.QtQuickWidgets` module was accidentally
  introduced. Since that module isn't packaged everywhere, it's been removed
  again.

v1.3.2
------

Fixed
~~~~~

- QtWebEngine: Improved workaround for a bug in Qt 5.11 where only the
  top/bottom half of the window is used.
- QtWebEngine: Work around a bug in Qt 5.11 where an endless loading-loop is
  triggered when clicking a link with an unknown scheme.
- QtWebEngine: When switching between pages with changed settings, less
  unnecessary reloads are done now.
- QtWebEngine: It's now possible to open external links such as `magnet://` or
  `mailto:` via hints.

v1.3.1
------

Fixed
~~~~~

- Work around a bug in Qt 5.11 where only the top/bottom half of the window is used.
  This workaround is incomplete, but fixes the majority of the cases where this happens.
- Work around keyboard focus issues with Qt 5.11.
- Work around an issue in Qt 5.11 where e.g. activating JavaScript per-domain
  needed a manual reload in some cases.
- Don't crash when a ² key is pressed (e.g. on AZERTY keyboards).
- Don't crash when a tab is opened and quickly closed again.


v1.3.0
------

Added
~~~~~

- New `:scroll-to-anchor` command to scroll to an anchor in the document.
- New `url.open_base_url` option to open the base URL of a searchengine when no
  search term is given.
- New `tabs.min_width` setting to configure the minimal width for tabs.
- New userscripts:
  * `getbib` to download bibtex information for DOIs on a page.
  * `qute-keepass` to get passwords from KeePassX.

Changed
~~~~~~~

- QtWebEngine: Support for JavaScript Shared Web Workers have been disabled on
  Qt versions older than 5.11 because of security issues in in Chromium.
  You can get the same effect in earlier versions via
  `:set qt.args ['disable-shared-workers']`. An equivalent workaround is also
  contained in Qt 5.9.5 and 5.10.1.
- The file dialog for downloads now has basic tab completion based on the
  entered text.
- `:version` now shows OS information for POSIX OS other than Linux/macOS.
- When there's an error inserting the text from an external editor, a backup
  file is now saved.
- The `window.hide_wayland_decoration` setting got renamed to
  `window.hide_decoration` and now also works outside of wayland.
- The `tabs.favicons.show` setting now can take three values: `'always'` (was
  `True`), `'never'` (was `False`) and `'pinned'` (to only show favicons for
  pinned tabs).
- Hover tooltips on tabs now always show the webpage's title.
- The default value for `content.host_blocking.lists` was changed to only
  include https://github.com/StevenBlack/hosts[Steven Black's hosts-list] which
  combines various sources.
- Error messages when trying to wrap when `tabs.wrap` is `False` are now logged
  to debug instead of messages.

Fixed
~~~~~

- Using hints before a page is fully loaded is now possible again.
- Selecting hints with the number keypad now works again.

  loaded correctly in some situations.
- The statusbar now more closely reflects the caret mode state.
- The icon on Windows should now be displayed in a higher resolution.
- The QtWebEngine development tools (inspector) now also work when JavaScript is
  disabled globally.
- Building `.exe` files now works when `upx` is installed on the system.
- The keyhint widget now shows the correct text for chained modifiers.
- Loading GreaseMonkey scripts now also works with Jinja2 2.8 (e.g. on Debian
  Stable).
- Adding styles with GreaseMonkey on fast sites now works properly.
- Window ID 0 is now excluded properly from `:tab-take` completion.
- A rare crash when cancelling a download has been fixed.
- The Makefile (intended for packagers) now supports `PREFIX` properly.
- The workaround for a black window with Nvidia graphics is now enabled on
  non-Linux systems (like FreeBSD) as well.
- Initial support for Qt 5.11.
- Checking for a new version after sending a crash report now works properly
  again.
- `@match` in Greasemonkey scripts now more closely matches the proper pattern
  syntax.
- Searching via `/` or `?` now doesn't handle any characters in a special way.
- Fixed crash when trying to retry some failed downloads on QtWebEngine.
- An invalid spellcheck dictionary filename now doesn't crash anymore.
- When no spellcheck dictionaries are configured, it's now disabled internally.
  This works around an issue with entering special characters on Facebook
  messenger.
- The macOS release now should work again on macOS 10.11 and newer.

v1.2.1
------

Fixed
~~~~~

- qutebrowser now starts properly when the PyQt5 QOpenGLFunctions package wasn't
  found.
- The keybinding cheatsheet on the quickstart page is now loaded from a local
  `qute://` URL again.
- With "tox -e mkvenv-pypi", PyQt 5.10.0 is used again instead of Qt 5.10.1,
  because of an issue with Qt 5.10.1 which causes qutebrowser to fail to start
  ("Could not find QtWebEngineProcess").

  from sessions.
- Shortcuts now correctly use `Ctrl` instead of `Command` on macOS again.

v1.2.0
------

Added
~~~~~

- Initial implementation of per-domain settings:
  * `:set` and `:config-cycle` now have a `-u`/`--pattern` argument taking a
    https://developer.chrome.com/extensions/match_patterns[URL match pattern]
    for supported settings.
  * `config.set` in `config.py` now takes a third argument which is the pattern.
  * New `with config.pattern('...') as p:` context manager for `config.py` to
    use the shorthand syntax with a pattern.
  * New `tsh` keybinding to toggle scripts for the current host. With a capital
    `S`, the toggle is saved. With a capital `H`, subdomains are included. With
    `u` instead of `h`, the exact current URL is used.
  * New `tph` keybinding to toggle plugins, with the same additional binding
    described above.
- New QtWebEngine features:
  * Caret/visual mode
  * Authentication via ~/.netrc
  * Retrying downloads with Qt 5.10 or newer
  * Hinting and other features inside same-origin frames
- New flags for existing commands:
  * `:session-load` has a new `--delete` flag which deletes the
    session after loading it.
  * New `--no-last` flag for `:tab-focus` to not focus the last tab when focusing
    the currently focused one.
  * New `--edit` flag for `:view-source` to open the source in an external editor.
  * New `--select` flag for `:follow-hint` which acts like the given string was entered but doesn't necessary follow the hint.
- New special pages:
  * `qute://bindings` (opened via `:bind`) which shows all keybindings.
  * `qute://tabs` (opened via `:buffer`) which lists all tabs.
- New settings:
  * `statusbar.widgets` to configure which widgets should be shown in which
    order in the statusbar.
  * `tabs.mode_on_change` which replaces `tabs.persist_mode_on_change`. It can
    now be set to `restore` which remembers input modes (input/passthrough)
    per tab.
  * `input.insert_mode.auto_enter` which makes it possible to disable entering
    insert mode automatically when an editable element was clicked. Together
    with `input.forward_unbound_keys`, this should allow for emacs-like
    "modeless" keybindings.
- New `:prompt-yank` command (bound to `Alt-y` by default) to yank URLs
  referenced in prompts.
- The `hostblock_blame` script which was removed in v1.0 was updated for the new
  config and re-added.
- New `cycle-inputs.js` script in `scripts/` which can be used with `:jseval -f`
  to cycle through inputs.

Changed
~~~~~~~

- Complete refactoring of key input handling, with various effects:
  * emacs-like keychains such as `<Ctrl-X><Ctrl-C>` can now be bound.
  * Key chains can now be bound in any mode (this allows binding unused keys in
    hint mode).
  * Yes/no prompts don't use keybindings from the `prompt` section anymore, they
    have their own `yesno` section instead.
  * Trying to bind invalid keys now shows an error.
  * The `bindings.default` setting can now only be set in a `config.py`, and
    existing values in `autoconfig.yml` are ignored.
- Improvements for GreaseMonkey support:
  * `@include` and `@exclude` now support regex matches. With QtWebEngine and Qt
    5.8 and newer, Qt handles the matching, but similar functionality will be
    added in Qt 5.11.
  * Support for `@requires`
  * Support for the GreaseMonkey 4.0 API
- The sqlite history now uses write-ahead logging which should be
  a performance and stability improvement.
- When an editor is spawned with `:open-editor` and `:config-edit`, the changes
  are now applied as soon as the file is saved in the editor.
- The `hist_importer.py` script now only imports URL schemes qutebrowser can
  handle.
- Deleting a prefix (`:`, `/` or `?`) via backspace now leaves command mode.
- Angular 1 elements and `<summary>`/`<details>` now get hints assigned.
- `:tab-only` with pinned tabs now still closes unpinned tabs.
- The `url.incdec_segments` option now also can take `port` as possible segment.
- QtWebEngine: `:view-source` now uses Chromium's `view-source:` scheme.
- Tabs now show their full title as tooltip.
- When there are multiple unknown keys in a autoconfig.yml, they now all get
  reported in one error.
- More performance improvements when opening/closing many tabs.
- The `:version` page now has a button to pastebin the information.
- Replacements like `{url}` can now be escaped as `{{url}}`.

Fixed
~~~~~

- QtWebEngine bugfixes:
  * Improved fullscreen handling with Qt 5.10.
  * Hinting and scrolling now works properly on special `view-source:` pages.

Fixed
~~~~~

- QtWebEngine: Crash with Qt 5.10.1 when using :undo on some tabs.
- Compatibility with Python 3.7

v1.1.1
------

Fixed
~~~~~

- The Makefile now actually works.
- Fixed crashes with Qt 5.10 when closing a tab before it finished loading.

v1.1.0
------

Added
~~~~~

- Initial support for Greasemonkey scripts. There are still some rough edges,
  but many scripts should already work.
- There's now a `misc/Makefile` file in releases, which should help
  distributions which package qutebrowser, as they can run something like
  `make -f misc/Makefile DESTDIR="$pkgdir" install` now.
- New fields for `window.title_format` and `tabs.title.format`:
  * `{current_url}`
  * `{protocol}`
- New settings:
  * `colors.statusbar.passthrough.fg`/`.bg`
  * `completion.delay` and `completion.min_chars` to update the completion less
    often.
  * `completion.use_best_match` to automatically use the best-matching
    command in the completion.
  * `keyhint.radius` to configure the edge rounding for the key hint widget.
  * `qt.highdpi` to turn on Qt's High-DPI scaling.
  * `tabs.pinned.shrink` (`true` by default) to make it possible
    for pinned tabs and normal tabs to have the same size.
  * `content.windowed_fullscreen` to show e.g. a fullscreened video in the
    window without fullscreening that window.
  * `tabs.persist_mode_on_change` to keep the current mode when
    switching tabs.
  * `session.lazy_restore` which allows to not load pages immediately
    when restoring a session.
- New commands:
  * `:tab-give` and `:tab-take`, to give tabs to another window, or take them
    from another window.
  * `:completion-item-yank` (bound to `<Ctrl-C>`) to yank the current
    completion item text.
  * `:edit-command` to edit the commandline in an editor.
  * `search.incremental` for incremental text search.
- New flags for existing commands:
  * `-o` flag for `:spawn` to show stdout/stderr in a new tab.
  * `--rapid` flag for `:command-accept` (bound to `Ctrl-Enter` by default),

    same effect they have with `:open`.
  * `--history` for `:completion-item-focus` which causes it to go
    through the command history when no text was entered. The default bindings for
    cursor keys in the completion changed to use that, so that they can be used
    again to navigate through completion items when a text was entered.
  * `--file` for `:debug-pyeval` which makes it take a filename instead of a
    line of code.
- New `config.source(...)` method for `config.py` to source another file.
- New `{line}` and `{column}` replacements for `editor.command` to position the
  cursor correctly.

Major changes
~~~~~~~~~~~~~

- Dependency changes:

    https://github.com/annulen/webkit/wiki[distributed independently from Qt])
    is dropped.
  * Support for Python 3.4 is dropped.
  * Support for Qt before 5.7.1 and PyQt before 5.7 is dropped.
  * New dependency on the QtSql module and Qt sqlite support.
  * New dependency on the http://www.attrs.org/[attrs] project (packaged as
    `python-attr` in some distributions).
  * The depedency on PyOpenGL (when using QtWebEngine) got removed. Note
    that PyQt5.QtOpenGL is still a dependency.
  * PyQt5.QtOpenGL is now always required, even with QtWebKit.
- The QtWebEngine backend is now used by default. Note this means that
  QtWebEngine now should be a required dependency, and QtWebKit (if new enough)
  should be changed to an optional dependency.
- Completely rewritten configuration system which ignores the old config file.
  See link:qute://help/configuring.html[] for details.
- Various documentation files got moved to the doc/ subfolder;
 `qutebrowser.desktop` got moved to misc/.

  completion is too slow on your machine, try setting it to a few 1000 items.
- Up/Down now navigates through the command history instead of selecting
  completion items. Either use Tab to cycle through the completion, or
  https://github.com/qutebrowser/qutebrowser/blob/master/doc/help/configuring.asciidoc#migrating-older-configurations[restore the old behavior].

Added
~~~~~

- QtWebEngine: Spell checking support, see the `spellcheck.languages` setting.

Changed
~~~~~~~

- Hints are now drawn natively in Qt instead of using web elements. This has a
  few implications for users:
    * The `hints -> opacity` setting does not exist anymore, but you can use
      `rgba(r, g, b, alpha)` colors instead for `colors -> hints.bg`.
    * The `hints -> font` setting is not affected by
      `fonts -> web-family-fixed` anymore. Thus, a transformer got added to
      change `Monospace` to `${_monospace}`.
    * Gradients in hint colors can now be configured by using `qlineargradient`
      and friends instead of `-webkit-gradient`. The most common cases get
      migrated automatically, but if you drastically changed the defaults,
      you'll need to manually adjust your config.
    * Styling hints by styling `qutehint` elements in `user-stylesheet` was
      never officially supported and does not work anymore.
    * Hints are now not affected by the page's stylesheet or zoom anymore.
- `:bookmark-add` now has a `--toggle` flag which deletes the bookmark if it
  already exists.
- `:bookmark-load` now has a `--delete` flag which deletes the bookmark after
  loading it.
- `:open` now also accepts quickmark names instead of URLs
- `:tab-move` now optionally takes an index for absolute moving.
- Commands taking either an argument or a count (like `:zoom` or `:tab-focus`)
  now prefer the count instead of showing an error message.
- `:open` now has an `--implicit` argument to treat the opened tab as implicit
  (i.e. to open it at the position it would be opened if it was a clicked link)
- `:download-open` and `:prompt-open-download` now have an optional `cmdline`
  argument to pass a commandline to open the download with.
- `:yank` now has a position argument to select what to yank instead of using
  flags.
- Replacements like `{url}` can now also be used in the middle of an argument.
  Consequently, commands taking another command (`:later`, `:repeat` and
  `:bind`) now don't immediately evaluate variables.
- Tab titles in the `:buffer` completion now update correctly when a page's
  title is changed via javascript.
- `:hint` now has a `--mode <mode>` flag to override the hint mode configured
  using the `hints -> mode` setting.
- With `new-instance-open-target` set to a tab option, the tab is now opened in
  the most recently focused (instead of the last opened) window. This can be
  configured with the new `new-instance-open-target.window` setting.
  It can also be set to `last-visible` to show the pages in the most recently
  visible window, or `first-opened` to use the first (oldest) available window.
- Word hints now are more clever about getting the element text from some elements.
- Completions for `:help` and `:bind` now also show hidden commands
- The `:buffer` completion now also filters using the first column (id).
- `:undo` has been improved to reopen tabs at the position they were closed.
- `:navigate` now takes a count for `up`/`increment`/`decrement`.
- The `hints -> auto-follow` setting now can be set to
  `always`/`full-match`/`unique-match`/`never` to more precisely control when
  hints should be followed automatically.
- Counts can now be used with special keybindings (e.g. with modifiers).
  This was already implemented for v0.7.0 originally, but got reverted because
  it caused some issues and then never re-applied.
- Sending a command to an existing instance (via "qutebrowser :reload") now
  doesn't mark it as urgent anymore.
- `tabs -> title-format` now treats an empty string as valid.
- Bindings for `:`, `/` and `?` are now configured explicitly and not hardcoded
  anymore.
- The `completion -> show` setting can now be set to `always`, `auto` or
  `never`.
- `:open-editor` can now be used in any mode.
- Lots of improvements to and bugfixes for the QtWebEngine backend, such as
  working hints. However, using qutebrowser directly from git is still advised
  when using `--backend webengine`.
- `content -> javascript-can-open-windows` got renamed to
  `javascript-can-open-windows-automatically`.
- `:prompt-accept` now optionally accepts a value which overrides the one
  entered in the input box. `yes` and `no` can be used as values for yes/no
  questions.
- The new `--qt-arg` and `--qt-flag` arguments can be used to pass
  arguments/flags to Qt's commandline.
- Error/warning/info messages are now shown stacked above the statusbar.
  This also added various new settings:
    * `colors -> messages.fg.error` (renamed from `statusbar.fg.error`)
    * `colors -> messages.bg.error` (renamed from `statusbar.bg.error`)
    * `colors -> messages.border.error`
    * `colors -> messages.fg.warning` (renamed from `statusbar.fg.warning`)
    * `colors -> messages.bg.warning` (renamed from `statusbar.bg.warning`)
    * `colors -> messages.border.warning`
    * `colors -> messages.fg.info`
    * `colors -> messages.bg.info`
    * `colors -> messages.border.info`
    * `fonts -> messages.error`
    * `fonts -> messages.warning`
    * `fonts -> messages.info`
- The `qute:settings` page now also shows option descriptions.
- `qute:version` and `qutebrowser --version` now show various important paths
- `:spawn`/userscripts now show a nicer error when a script wasn't found
- Various functionality now works when javascript is disabled with QtWebKit
- Various commands/settings taking `left`/`right`/`previous` arguments now take
  `prev`/`next`/`last-used` to remove ambiguity.
- The `ui -> user-stylesheet` setting now only takes filenames, not CSS snippets
- `ui -> window-title-format` now has a new `{backend} ` replacement
- `:hint` has a new `--add-history` argument to add the URL to the history for
  yank/spawn targets.
- `:set` now cycles through values if more than one argument is given.
- `:open` now opens `default-page` without a URL even without `-t`/`-b`/`-w` given.

Deprecated
~~~~~~~~~~

- The `:paste` command got deprecated as `:open` with `{clipboard}` and
  `{primary}` can be used instead.
- The `:paste-primary` command got deprecated as `:insert-text {primary}` can
  be used instead.

  `:prompt-accept yes` and `:prompt-accept no` can be used instead.

Removed
~~~~~~~

- The `:yank-selected` command got merged into `:yank` as `:yank selection`
  and thus removed.
- The `:completion-item-prev` and `:completion-item-next` commands got merged
  into a new `:completion-focus {prev,next}` command and thus removed.

  X .app currently.
- Hide Harfbuzz warning with the macOS .app

v0.8.0
------

Added
~~~~~

  Note that two former default bundings conflict with that binding, unbinding
  them via `:unbind .i` and `:unbind .o` is recommended.
- New `qute:bookmarks` page which displays all bookmarks and quickmarks.
- New `:prompt-open-download` (bound to `Ctrl-X`) which can be used to open a
  download directly when getting the filename prompt.
- New `{host}` replacement for tab- and window titles which evaluates
  to the current host.

Removed
-------

  `ui ->  display-statusbar-messages` setting.
- The `general -> wrap-search` setting as searches now always wrap.
  According to a quick straw poll and prior crash logs, almost nobody is using
  `wrap-search = false`, and turning off wrapping is not possible with
  QtWebEngine.
- `:edit-url` now doesn't accept a count anymore as its behavior was confusing
  and it doesn't make much sense to add a count.

  following a hint when filtering in number mode.
- New `:history-clear` command to clear the entire history
- New `hints -> find-implementation` to select which implementation (JS/Python)

  As a consequence, URLs which redirect to another URL are now added to the
  history too, marked with a `-r` suffix to the timestamp field.

Fixed
-----

- Fixed using `:hint links spawn` with flags - you can now use things like the
  `-v` argument for `:spawn` or pass flags to the spawned commands.

- Added workaround for a Qt/PyQt bug which is too weird to describe here

v0.6.0
------

Added
~~~~~

- New `:buffer` command to easily switch tabs by name. This is not bound to a
  key by default for existing users due to a conflict with the `gt`/`gT`
  bindings (which are now removed from the default bindings).
  You can bind it by hand by running `:bind -f gt set-cmd-text -s :buffer`.
- New `--quiet` argument for the `:debug-pyeval` command to not open a tab with
  the results. Note `:debug-pyeval` is still only intended for debugging.

  for hints instead of single characters.
- New `--all` argument for `:download-cancel` to cancel all running downloads.

- Improved performance when scrolling with many tabs open.
- Shift-Insert now also pastes primary selection for prompts.
- `:download-remove --all` got un-deprecated to provide symmetry with
  `:download-cancel --all`. It does the same as `:download-clear`.

- Don't remove `qutebrowser-editor-*` temporary file if editor subprocess crashed
- Userscripts are also searched in `/usr/share/qutebrowser/userscripts`.

Changed
~~~~~~~

- *Breaking change for userscripts:* `QUTE_HTML` and `QUTE_TEXT` for userscripts now don't store the contents directly, and instead contain a filename.
- The `content -> geolocation` and `notifications` settings now support a `true` value to always allow those. However, this is *not recommended*.

Changed
~~~~~~~

- Ignore quotes with maxsplit-commands (`:open`, `:quickmark-load`, etc.) and don't quote arguments for those commands in the completions. This also means some commands needed adjustments:

- Add tab index display to the statusbar.
- Keep progress bar height fixed when the statusbar is multiline.
- Many improvements to tests and related infrastructure:
    * `init_venv.py` and `run_checks.py` have been replaced by http://tox.readthedocs.org/[tox]. Install tox and run `tox -e mkvenv` instead.
