noiwid/HAFamilySafety v2.3.0 on GitHub

New

Extra time on Windows: add_time_bonus / cancel_time_bonus take platform: Windows, through Microsoft's device-limits overrides (as when a request for more time is approved). Windows Allowed Now and Time Remaining count it, and Time Remaining gives extra_time_until.
Extra time on the Family Safety card: a bar with Reset and +15 / +30 / +60 minutes free from now, and a timer button that opens the extra time sheet (duration, Add / Stop, the extra time in force shown as a pill). It is a window from now, not minutes added to the day. bonus: false hides the bar (same key as the Google Family Link card, inspired by noiwid/HAFamilyLink#246).
Screen time cards (shared with Google Family Link): a day of the history opens its hourly chart; Polish, Spanish and German.

Xbox limit numbers and the Xbox Screen Time Limits switch write through Xbox Family Settings only (#90, thanks @theSiegs). Without the Xbox Family Settings link they now fail with a clear message instead of writing the mobile Xbox schedule, which the console ignores.
Windows and Mobile locks read unknown until Microsoft has given the lock state (#89, thanks @theSiegs), instead of showing the platform as unlocked; Windows Allowed Now does not report on meanwhile.
Mobile schedule writes are sent one at a time (#92, thanks @theSiegs): setting a whole week at once no longer drops writes or sends a stale day back.
Family Safety card: status right under the title, tab labels down to 405 px, a back arrow on a sheet opened from another one, sheets that fit the visible height on phones, the Microsoft account link as a pill in the settings sheet, and "Renew the Microsoft link", which opens the integration's page.
The cards' URL carries the file date, so browsers and the mobile app fetch a changed card after a restart.

Schedule restore point: a lock, or a second "limits off" after the web fallback, no longer saves the 24 h week over the child's real schedule; turning screen time limits on no longer unlocks a locked child; a day changed during a lock is kept at unlock.
An HTML page answered with status 200 by Microsoft's Family web API counts as a failure, not a done write.
App ids are encoded in the app limit and pause requests (a desktop app name with #, ? or / sent the write elsewhere).
Manual sign-in (entries without Xbox on an HTTP-only instance): the same account cannot be added twice, a reauth into another account is refused, and the step is offered for reauth too.
Site lists, day slots, pending requests and paused apps are kept out of the history database.
Screen time cards: a card left open past midnight takes the new day's limit, the day ends at the next midnight on 23 h and 25 h days, a failed history read no longer freezes the history until midnight, and a failed load is shown.
Family Safety card: stops watching its size and closes its sheet when removed from the page.

Everything since 2.2.0, including the 2.3.0rc1 to rc3 pre-releases. Full list: #86, #87, #88, #89, #90, #92.
