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_.
- New bindings `<Ctrl-R>` (rapid), `<Ctrl-F>` (foreground) and `<Ctrl-B>` (background) to switch hint modes while hinting.
- `<Ctrl-M>` and numpad-enter are now bound by default for bindings where `<Return>` was bound.
- `:hint tab` and `F` now respect the `background-tabs` setting. To enforce a foreground tab (what `F` did before), use `:hint tab-fg` or `;f`.
- `:scroll` now takes a direction argument (`up`/`down`/`left`/`right`/`top`/`bottom`/`page-up`/`page-down`) instead of two pixel arguments (`dx`/`dy`). The old form still works but is deprecated.
- The `ui -> user-stylesheet` setting now also takes file paths relative to the config directory.

- Alternating row colors in completion. This adds a new `colors -> completion.alternate-bg` option.

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:
- Clear search when `:search` without arguments is given. (`:search ""` will now search for the literal text `""`)
- Add `-s`/`--space` argument to `:set-cmd-text` (as `:set-cmd-text "foo "` will now set the literal text `"foo "`)

- Expand environment variables in config settings which take a file path.
- Add a list of common user agents to the user agent setting completion.
- Move cursor to end of textboxes when hinting.
- Don't start searches on invalid URLs for quickmarks/startpage.
- Various performance improvements for the completion.
- Always open URLs given as argument in the foreground.
- Improve various error messages.
- Add `startpage`/`default-page` values to `tabs -> last-close`.
- Various improvements to `:restart` - it should be more robust now and uses sessions so all state (focused tab, scroll position, etc.) gets remembered.
- 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- `init_venv.py` and `run_checks.py` have been replaced by [tox](http://tox.readthedocs.org/). Install tox and run `tox -e mkvenv` instead.
