Summary

  • raise Decimal's minimum supported Elixir version from 1.12 to 1.15
  • move the lower CI pair from Elixir 1.12 / OTP 24 to Elixir 1.15 / OTP 26
  • record the compatibility change under the unreleased changelog

Why this matters

ExDoc v0.40 requires Elixir 1.15 and adds native Markdown documentation and llms.txt generation. Raising the runtime floor separately keeps that compatibility decision explicit instead of hiding it inside a documentation-tool update.

This also moves the project's tested baseline onto a substantially newer compiler and OTP generation while retaining the existing current-runtime CI pair.

Compatibility

This intentionally drops support for Elixir 1.12 through 1.14. It does not change Decimal's source or public API. The lower CI job now verifies the proposed minimum directly.

Verification

  • mix format --check-formatted mix.exs
  • MIX_ENV=test mix deps.unlock --check-unused
  • MIX_ENV=test mix compile --warnings-as-errors
  • MIX_ENV=test mix test — 266 passed (105 doctests, 36 properties, 125 tests)
