ELIXIR FIXES CALENDAR AND COMPILER EDGE CASES ACROSS FIVE PATCHES

Alexander Gubarev landed five targeted fixes to Calendar.ISO and ParallelCompiler that close gaps in time parsing, validation guards, and documentation.

The Calendar.ISO module got the heaviest attention, with fixes landing for millisecond precision validation [1], negative zero offset parsing in basic format [2], and self-referencing documentation bugs in datetime conversion functions [3]. These are not breaking changes, but they resolve real edge cases that hit developers working with strict time validation and ISO 8601 parsing. On the documentation front, kernel docs got wording clarifications [4] and ParallelCompiler had typos and phrasing tightened [5]. All five PRs came from the same contributor in a single push, suggesting these were discovered and addressed in a coordinated audit pass. The fixes are narrow and surgical, the kind that ship without ceremony but save debugging time downstream.
