ECTO CRACKS DOWN ON SILENT QUERY TYPOS WHILE PHOENIX LOCKS DOWN CHANNELS

Ecto is now warning on the most common query mistake developers make, and Phoenix just closed a resource exhaustion hole that could let a single client starve your infrastructure.
Ecto shipped a deprecation warning for field access written with empty parentheses like `q.title()` [1], a typo that silently behaves identically to `q.title` and has been the source of quiet bugs for years. This warning phase buys you time before it becomes a hard error, so update your codebase now. On the Phoenix side, the framework added a cap on the number of channels a single transport process can join [2], preventing one malicious or broken client from spinning up unbounded processes and tanking your server. Meanwhile, UUID enthusiasts get a win with Ecto adding `timestamp/1`, `datetime/1`, and `version/1` helpers for UUID v7 [3], finally giving you control over timestamps when migrating legacy data. Phoenix LiveView 1.2.6 landed with a fix for HTMLFormatter mangling multi-codepoint emojis in templates [4], a rare but annoying edge case. On the documentation front, Elixir core improved typespecs and docstrings across the standard library [5], with added specs for `Code.Fragment.lines/1` and corrections to `MapSet.split_with/2` that now reflect actual implementation behavior.
Action items
- → Audit your Ecto queries for `field()` syntax and refactor before the warning becomes an error elixir-ecto/ecto [plan]
- → Upgrade to Phoenix 1.8+ to get channel join limits if you're running public-facing LiveView apps phoenixframework/phoenix [plan]
- → Update to LiveView 1.2.6 if you're generating HTML with emoji phoenixframework/phoenix_live_view [monitor]
- → Pull the latest Elixir docs to confirm your typespecs match the standard library elixir-lang/elixir [monitor]
