Qutebrowser

Fixed
- Fixed crash when using `:tab-{prev,next,focus}` right after closing the last
tab with `last-close` set to `close`.
- Fixed crash when doing `:undo` in a new instance with `tabs -> last-close` set
to `default-page`.
- Fixed crash when starting with --cachedir=""
- Fixed crash in some circumstances when using dictionary hints
- Fixed various crashes related to PyQt 5.6

Fixed
- Fixed broken cheatsheet image which was missing from package
- Fixed occasional crash when switching/disconnecting monitors
- Fixed crash when downloading non-ascii files with a broken locale (`LC_ALL=C`)
- Added workaround for a Qt/PyQt bug which is too weird to describe here

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.
- The completion now matches each entered word separately.
- A new command `:paste-primary` got added to paste the primary selection, and
`<Shift-Insert>` got added as a binding so it pastes primary rather than
clipboard.
- New mode `word` for `hints -> mode` which uses a dictionary and link-texts
for hints instead of single characters.
- New `--all` argument for `:download-cancel` to cancel all running downloads.
- New `password_fill` userscript to fill passwords using the `pass` executable.
- New `current` hinting mode which forces opening hints in the current tab
(even with `target="_blank"`)

Changed
- Pasting multiple lines via `:paste` now opens each line in a new tab.
- `:navigate increment/decrement` now preserves leading zeroes in URLs.
- `general -> editor` can now also handle `{}` inside another argument (e.g. to open `vim` via `termite`)
- 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`.
- Improved detection of URLs/search terms when pasting multiple lines.
- Don't remove `qutebrowser-editor-*` temporary file if editor subprocess crashed
- Userscripts are also searched in `/usr/share/qutebrowser/userscripts`.
- Blocked hosts are now also read from a `blocked-hosts` file in the config dir
(e.g. `~/.config/qutebrowser/blocked-hosts`).

Fixed
- Fixed starting with -c "".
- Fixed crash when a tab is closed twice via javascript (e.g. Dropbox
authentication dialogs)
- Fixed crash when a notification/geolocation prompt is answered after closing
the tab it belongs to.
- Fixed crash when downloading a file without any path information (e.g a
magnet link).
- Fixed crashes when opening an empty URL (e.g. via pasting).
- Fixed validation of duplicate values in `hints -> chars`.
- Fixed crash when PDF.js was partially installed.
- Fixed crash when XDG_DOWNLOAD_DIR was not an absolute path.
- Fixed very long filenames when downloading `data://`-URLs.
- Fixed ugly UI fonts on Windows when Liberation Mono is installed
- Fixed crash when unbinding key from a section which doesn't exist in the config
- Fixed report window after a segfault
- Fixed some directory browser issues on Windows
- Fixed crash when closing a window with a finished download and delayed
`remove-finished-downloads` setting.
- Fixed crash when hitting `<Tab>` then `<Ctrl-C>` on pages without keyboard
focus.
- Fixed "Frame load interrupted by policy change" error showing up when
downloading files with Qt 5.6.

Removed
- The `gt`/`gT` bindings (luakit-like alternatives to `J`/`K`) were removed
(except for existing configs) to make room for the `gt` binding to show
buffers.

Fixed
- Fixed completion for various config values when using `:set`.
- Fixed config validation for various config values.
- Prevented an error being logged when a website with HTTP authentication was
opened on Windows.

Added
- Ability to preview PDFs using pdf.js in the browser if it's installed. This
is disabled by default and can be enabled using the
`content -> pdfjs-enabled` setting.
- New setting `ui -> hide-wayland-decoration` to hide the window decoration
when using wayland.
- New userscripts in `misc/userscripts`:
- `open_download` to easily open a file in your downloads folder.
- `view_in_mpv` to open a video in mpv and remove it from the page.
- `qutedmenu` and `dmenu_qutebrowser` to select URLs via dmenu
- New setting `content -> host-blocking-whitelist` to whitelist certain domains
from the adblocker.
- `{scroll_pos}` can now be used in `ui -> window-title-format` and
`tabs -> title-format`.
- New setting `general -> url-incdec-segments` to configure which segments of
the URL should be affected by `:navigate increment/decrement`.
- New `--target` argument to specify how URLs should be opened in an existing
instance.
- New setting `statusbar.url.fg.success.https` to set the foreground color for
the URL when a page was loaded via HTTPS.
- The scrollbar in the completion is now styled, and the following new options
got added:
- `completion -> scrollbar-width`
- `completion -> scrollbar-padding`
- `colors -> completion.scrollbar.fg`
- `colors -> completion.scrollbar.bg`
- New value `none` for options taking a color system so they don't display a
gradient:
- `colors -> tabs.indicator.system`
- `colors -> downloads.fg.system`
- `colors -> downloads.bg.system`
- New command `:download-retry` to retry a failed download.
- New command `:download-clear` which replaces `:download-remove --all`.
- `:set-cmd-text` has a new `--append` argument to append to the current
statusbar text.
- qutebrowser now uses `~/.netrc` if available to authenticate via HTTP.
- New `:fake-key` command to send a fake keypress to a website or to
qutebrowser.
- New `--mhtml` argument for `:download` to download a page including all
ressources as MHTML file.
- New option `tabs -> title-alignment` to change the alignment of tab titles.

Changed
- The `colors -> tabs.bg/fg.selected` option got split into
`tabs.bg/fg.selected.odd/even`.
- `:spawn --userscript` and `:hint` with the `userscript` target now look up
relative paths in `~/.local/share/qutebrowser/userscripts` or
`$XDG_DATA_DIR`. Using a binary in `$PATH` won't work anymore with
`--userscript`.
- New design for error pages
- Link filtering for hints now checks if the text is contained anywhere in
the link, and matches case-insensitively.
- The `ui -> remove-finished-downloads` option got changed to an integer and
now takes a time (in milliseconds) to keep the download around after it's
finished. When set to `-1`, downloads are never removed.
- The `:follow-hint` command now optionally takes the keystring of a hint to
follow.
- `:scroll-px` now doesn't take floats anymore, which made little sense.
- Updated the user agent list for the `:set network user-agent` completion.
- Starting with `--debug` doesn't log `VDEBUG` messages anymore (add
`--loglevel VDEBUG` to get them).
- `:debug-console` now hides the console if it's already shown.
- `:yank-selected` now doesn't log the selected text anymore.
- `general -> log-javascript-console` got changed from a boolean to an option
taking a loglevel (`none`, `info`, `debug`).
- `:tab-move +/-` now wraps around if `tabs -> wrap` is `true`.
- When a subprocess (like launched by `:spawn`) fails, its stdout/stderr is now
logged to the console.
- A search engine name can now contain any non-space character, like dashes.

Deprecated
- `:download-remove --all` is now deprecated and `:download-clear` should be
used instead.
