Phoenix shipped a patch release that fixes a channel bug silently dropping messages without a join_ref, and LiveView is quietly rewriting the rules of navigation.

Phoenix 1.8.12 is out [1], fixing two bugs: the return_to session key now clears after login [2] and channel messages without a join_ref are no longer dropped [3]. The join_ref issue was introduced in 1.8.3 and violated the documented protocol, which "explicitly allows non join messages to omit the join_ref" [4]. On the Elixir side, performance work continues with fast paths for Calendar.ISO.iso_days_to_unit/2 that short-circuit the same-unit case [5], plus a type checker crash fix for non-returning `for ... into:` expressions [6]. LiveView is the busy desk: a new `navigation_type/2` API [7] answers the forum plea to control cross-session navigation warnings, while another PR lets you opt out of the phx-remove cascade on navigation [8] and a third makes phx-drop-target-active more reliable [9]. External metadata failures now surface consistently in `upload_errors/2` as `{:external_metadata_failure, meta}` and auto-uploads report them too [10]. The activity across all three repos: 18 commits, 10 PRs, 2 releases.
