A notable breaking change in OTP 28 requires regexes defined in module attributes to be moved inline. Enhancements include a new IEx.Helpers.process_info/1 function, Mix --no-listeners option for compile and run commands, and per-OTP-release Hex/Rebar installation. Bug fixes address trace event emission for various Kernel callbacks, map union optimization, crash fixes for nested bitstrings and struct defaults, and regex recompilation for OTP 28 compatibility. ## Full article daily.dev links to this article rather than hosting it.
