Elixir v1.20.1 released

1. Security

Elixir

  • [Version] Limit integer components in Version to 14 decimal bytes, to avoid parsing too large integers from untrusted user input. We strongly advise developers parsing versions from user input to limit the data size given to the Version module (CVE-2026-49762, GHSA-w2h8-8x3g-278p)

2. Bug fixes

Elixir

  • [Calendar] Cap width in Calendar.strftime/2 to 1024 characters
  • [Code] Ensure Code.require_file releases the file if compilation fails
  • [Kernel] Fix documentation generation to use the correct version in search

Mix

  • [mix archive.install] Validate paths and files when extracting archives
  • [mix format] Honor --no-compile option when loading plugins
