Phoenix LiveView 1.2 is live with better error tracking and a critical fix for HEEx whitespace handling that broke case/when templates.

LiveView 1.2 [1] arrived with three meaningful wins: telemetry events now wrap component render updates [2], connect redirects properly surface events instead of dropping them, and the HEEx compiler no longer chokes on multiline case expressions [3]. That last fix matters because templates like `<%= case @x do %>` followed by separate `<% :foo -> %>` tags were silently broken in 1.1. Elixir's set operations got a major internal refactor [7] that splits union, intersection, and difference into bare and optimized paths, reducing duplication but requiring careful review of the Descr module's usage. Phoenix framework itself bumped six JavaScript dependencies [4] including Babel 7.29.7 and eslint 10.4.1, and released v1.8.8 [5] alongside LiveView 1.2 generator updates [6]. The ecosystem is moving in sync: LiveView 1.2 generators are baked into Phoenix 1.8.8, so if you're on that version, you get the new codegen out of the box.

Action items

→ Upgrade to Phoenix LiveView 1.2 if you have multiline HEEx templates with case/when or try/rescue phoenixframework/phoenix_live_view [plan]
→ Update to Phoenix 1.8.8 to sync with LiveView 1.2 generators phoenixframework/phoenix [plan]
→ Review Elixir set operation changes in descr.ex if you maintain performance-critical code paths elixir-lang/elixir [monitor]
