ELIXIR LOADER TIGHTENS REQUIREMENT CHECKS
By RepoJournal · Filed · About Elixir & Phoenix · Composed from the cited sources · methodology
Elixir fixed a gap in the loader that could silently skip missing requirements, catching a class of bugs that slip through at compile time.
The Elixir team patched the loader to enforce requirement checks more strictly [1], preventing a subtle bug where missing dependencies could go undetected until runtime. This is the kind of fix that doesn't break anything but stops bad code from shipping in the first place. In related cleanup, the docs were clarified on when protocols load in the module lifecycle [2], settling a long-standing question about initialization order. Both changes land in the next release and are low-risk upgrades. If you've been burned by mysterious dependency issues at 3am, pay attention to the requirement validation change.
