[1.1.0] - 2026-05-31

Added

  • test coverage of lager_transform
  • OTP 28.5 to CI
  • OTP 29.0 to CI

Changed

  • logging calls to gate evaluation on a compile-time logger:allow/2 level check (mirroring logger's own ?LOG_* macros and lager's original inlined level check), replacing the previous heuristic that conditionally wrapped "expensive" arguments in a fun
  • log format and argument expressions to be evaluated only when the log level is enabled, restoring lager's original semantics; previously, arguments deemed inexpensive were evaluated unconditionally. As a result, the evaluation of a log argument — including any side effects and exceptions it may raise — now occurs only when the level is enabled; a previously-unconditional crash in a log argument will be masked while that level is disabled
  • parse transform to walk the AST through erl_syntax_lib rather than by blindly decomposing tuples, hardening the rewrite across all expression shapes
