Add more macOS versions

This fixes some focus issues after Qt 5.11 changes. There might be better ways
to solve them, but for now, this will work.

See https://codereview.qt-project.org/#/c/221408/10 and #3661:
https://github.com/qutebrowser/qutebrowser/issues/3661#issuecomment-375969315

Might also negatively affect #3834 as it essentially reintroduces QTBUG-52999 on
any Qt version: https://bugreports.qt.io/browse/QTBUG-52999

Might be reverted at a later date, but for now, I want an easy way to make tests
work on Qt 5.11 to spot further issues.

 // `Fixed` for any bug fixes.
 // `Security` to invite users to upgrade in case of vulnerabilities.
 
+v1.3.0 (unreleased)
+-------------------
+
+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 `getbib` userscript to download bibtex information for DOIs on a page.
+
+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.
+- Tab titles for tabs loaded from sessions should now really be correct instead
+  of showing the URL.
+- Loading URLs with customized settings from a session now avoids an additional
+  reload.
+- The window icon and title now get set correctly again.
+- The `tabs.switching_delay` setting now has a correct maximum value limit set.
+- The `taskadd` script now works properly when there's multi-line output.
+- QtWebEngine: Worked around issues with GreaseMonkey/stylesheets not being
+  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
+
+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").
+- Unbinding keys which were bound in older qutebrowser versions now doesn't
+  crash anymore.
+- Fixed a crash when reloading a page which wasn't fully loaded with v1.2.0
+- Keys on the numeric keypad now fall back to the same bindings without `Num+`
+  if no `Num+` binding was found.
+- Fixed hinting on some pages with Qt < 5.10.
+- Titles are now displayed correctly again for tabs which are cloned or loaded
+  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.
+  * Scroll positions are now restored correctly from sessions.
+  * `:follow-selected` should now work in more cases with Qt > 5.10.
+  * Incremental search now flickers less and doesn't move to the second result
+    when pressing Enter.
+  * Keys like `Ctrl-V` or `Shift-Insert` are now correctly handled/filtered with
+    Qt 5.10.
+  * Fixed hangs/segfaults on exit with Qt 5.10.1.
+  * Fixed favicons sometimes getting cleared with Qt 5.10.
+  * Qt download objects are now cleaned up properly when a download is removed.
+  * JavaScript messages are now not double-HTML escaped anymore on Qt < 5.11
+- QtWebKit bugfixes:
+  * Fixed GreaseMonkey-related crashes.
+  * `:view-source` now displays a valid URL.
+- URLs containing ampersands and other special chars are now shown correctly
+  when filtering them in the completion.
+- `:bookmark-add "" foo` can now be used to save the current URL with a custom
+  title.
+- `:spawn -o` now waits until the process has finished before trying to show the
+  output. Previously, it incorrectly showed the previous output immediately.
+- Suspended pages now should always load the correct page when being un-suspended.
+- Exception types are now shown properly with `:config-source` and `:config-edit`.
+- When using `:bookmark-add --toggle`, bookmarks are now saved properly.
+- Crash when opening an invalid URL from an application on macOS.
+- Crash with an empty `completion.timestamp_format`.
+- Crash when `completion.min_chars` is set in some cases.
+- HTML/JS resource files are now read into RAM on start to avoid crashes when
+  changing qutebrowser versions while it's open.
+- Setting `bindings.key_mappings` to an empty value is now allowed.
+- Bindings to an empty commands are now ignored rather than crashing.
+
+Removed
+~~~~~~~
+
+- `QUTE_SELECTED_HTML` is now not set for userscripts anymore except when called
+  via hints.
+- The `qutebrowser_viewsource` userscript has been removed as
+  `:view-source --edit` can now be used.
+- The `tabs.persist_mode_on_change` setting has been removed and replaced by
+  `tabs.mode_on_change`.
+
+v1.1.2
+------
+
+Changed
+~~~~~~~
+
+- Windows/macOS releases now bundle Qt 5.10.1 which includes security fixes from
+  Chromium up to version 64.0.3282.140.
+
+Fixed
+~~~~~
+
+- QtWebEngine: Crash with Qt 5.10.1 when using :undo on some tabs.
+- Compatibility with Python 3.7
+
+v1.1.1
+------

+Is qutebrowser secure?::
+    Most security issues are in the backend (which handles networking,
+    rendering, JavaScript, etc.) and not qutebrowser itself.
++
+qutebrowser uses http://wiki.qt.io/QtWebEngine[QtWebEngine] by default.
+QtWebEngine is based on Google's https://www.chromium.org/Home[Chromium]. While
+Qt only updates to a new Chromium release on every minor Qt release (all ~6
+months), every patch release backports security fixes from newer Chromium
+versions. In other words: As long as you're using an up-to-date Qt, you should
+be recieving security updates on a regular basis, without qutebrowser having to
+do anything. Chromium's process isolation and
+https://chromium.googlesource.com/chromium/src/+/master/docs/design/sandbox.md[sandboxing]
+features are also enabled as a second line of defense.
++
+http://wiki.qt.io/QtWebKit[QtWebKit] is also supported as an alternative
+backend, but hasn't seen new releases
+https://github.com/annulen/webkit/releases[in a while]. It also doesn't have any
+process isolation or sandboxing.
++
+Security issues in qutebrowser's code happen very rarely (as per March 2018,

+are fixed timely. To report security bugs, please contact me directly at

     qutebrowser if it is not running already. Also check if you want
     to use webengine as backend in line 17 and change it to your
     needs.
+
+How do I make qutebrowser use greasemonkey scripts?::
+    There is currently no UI elements to handle managing greasemonkey scripts.
+    All management of what scripts are installed or disabled is done in the
+    filesystem by you. qutebrowser reads all files that have an extension of
+    `.js` from the `<data>/greasemonkey/` folder and attempts to load them.
+    Where `<data>` is the qutebrowser data directory shown in the `Paths`
+    section of the page displayed by `:version`. If you want to disable a
+    script just rename it, for example, to have `.disabled` on the end, after
+    the `.js` extension. To reload scripts from that directory run the command
+    `:greasemonkey-reload`.
++
+Troubleshooting: to check that your script is being loaded when
+`:greasemonkey-reload` runs you can start qutebrowser with the arguments
+`--debug --logfilter greasemonkey,js` and check the messages on the
+program's standard output for errors parsing or loading your script.
+You may also see javascript errors if your script is expecting an environment
+that we fail to provide.
++
+Note that there are some missing features which you may run into:
+
+. Some scripts expect `GM_xmlhttpRequest` to ignore Cross Origin Resource
+  Sharing restrictions, this is currently not supported, so scripts making
+  requests to third party sites will often fail to function correctly.
+. If your backend is a QtWebEngine version 5.8, 5.9 or 5.10 then regular
+  expressions are not supported in `@include` or `@exclude` rules. If your
+  script uses them you can re-write them to use glob expressions or convert
+  them to `@match` rules.
+  See https://wiki.greasespot.net/Metadata_Block[the wiki] for more info.
+. Any greasemonkey API function to do with adding UI elements is not currently
+  supported. That means context menu extentensions and background pages.
