Luakit 2017-07-26

Required WebKitGTK+ version: 2.14+
A relatively recent version of GTK+ 3 is required; some features are not available on older versions.

Added

Adblock module

The adblock module previously available at https://github.com/luakit/luakit-plugins has been included into the main luakit repository, with the following changes:

Ported adblock module to use WebKit 2 compatible APIs. This breaks compatibility with WebKit 1.
Added color-coding to adblock filter list status indicator.
The Adblock chrome page CSS has been updated to be more consistent with other luakit chrome pages.
An enable/disable button has been added to the Adblock chrome page.
The adblock chrome page has received several other refactors and improvements.
Adblock no longer blocks ads on local files (pages on the file:// scheme).
Adblock no longer blocks data URIs for performance reasons.
Added links for quickly enabling/disabling filter lists to adblock chrome page.
Made adblock.enabled writeable, and removed adblock.state() function.
Adblock now blocks pages from being loaded until all filter list rules are fully loaded.
Adblock now enables newly-added filter lists by default.
Fixed a bug where luakit would not start if the adblock subscriptions file was missing.
Fixed broken :adblock-reload command.
Improved the consistency and formatting of adblock log messages.
Fixed a bug where the adblock subscriptions file would become corrupted.
Adblock simple mode has been removed.
Fixed parsing of adblock filter list rules containing '#'.
Fixed a bug where adblock would incorrectly block URIs on many domains, due to an design flaw.
Adblock now displays an error page when the adblock module blocks a page navigation.
Improved filter list rule length and ignore count calculation.
Added several optimizations for rule matching that significantly improve performance.

Error pages

A new module, error_page.lua, allows customization of luakit error pages, such as those displayed when a page fails to load.

Luakit error pages are now displayed with a nicer interface, provided by error_page.lua
Chrome page errors are now displayed with the error_page.lua module interface.
Error pages now show information about the current proxy, as unintended proxy use can be responsible for page load failures.
Error pages can now be customized with user CSS.

User styles

A new module, styles.lua, supports user stylesheets with @-moz-document sections. User stylesheets from https://userstyles.org are supported.

Luakit now automatically detects and parses user stylesheets on startup.
Added support for enabling/disabling user stylesheets immediately, without refreshing the page.
Added the :styles-list command to display the user stylesheets menu.
Added the :styles-reload command to reload all user stylesheet files from disk.

A testing framework has been added that supports asynchronous tests.

The status bar and the tab bar are now hidden when luakit is fullscreen.
GLib logs are now funneled through luakit's log system.

An error message is now shown when the formfiller module fails to fill a form.
The undoclose menu is now automatically closed when there are no more menu entries.
Closed tabs are now saved in the luakit session file, so undoclose now works across sessions.

All uses of module() in Lua code have been removed.
Most variables have been made non-global.
A follow mode heuristic has been added for links that contain a single image element.

A developer warning is now printed if the web extension binary is not found.
Luakit is now completely restarted if loading a configuration file fails.

Tabs now have a themable hover color.

The formfiller now supports automatically filling forms when pages have finished loading. This is useful for automatically logging in to certain sites.
Added export_funcs parameter to chrome.add().

The :javascript command now has improved error handling.
luakit:// URIs are no longer added to history.
Download objects now have the allow_overwrite property.
