Drafting:

Recent changes:

• New pages are shown at the start of a site's feed
• Log entries are shown at the end of a site's feed
• Basic validation has been added to user settings, applied before saving

Upcoming changes:

• Expanded validation, which will verify sites provided are valid wikimedia foundation sites, will be added

Backwards compatibility:

• BREAKING CHANGE: Backwards compatibility supporting the use of sites as '*.*.org' (like 'en.wikipedia.org' or 'meta.wikimedia.org'), deprecated in version 1.7.5, will be removed; all sites should now be saved as '*.*' (like 'de.wikinews' or 'fr.wikisource')
• BREAKING CHANGE: Storing user sites as window.GlobalWatchlistSites, deprecated in version version 1.11.11, will be removed; all settings should be stored in the window.GlobalWatchlistConfig object
• Both of these breaking changes will be implemented alongside version 4.0; until then, any use of the config page ( [[:meta:Special:BlankPage/GlobalWatchlistConfig]] ) will result in saving settings in the current format

Next release:
Version 4.0 should be released in around a week. It will include the new features mentioned above, as well as removal of backwards compatibility for settings and sites.
