Apply to OTP 27 code, releases, distribution, native boundaries, and operations.

Versions and supply chain

  • Build/redeploy each newest OTP 27 release. OTP patches only each supported major's latest minor (27.3 for OTP 27), and supports three newest majors: OTP 27 leaves support when OTP 30 ships. This title's 27 is the release line; researched 27.3.4.17 is not an install recommendation. BEAM overlay titles likewise identify researched releases.
  • Rebuild line-following images such as erlang:27 with docker build --pull, or bot-updated digests. Verify exact Dockerfile/.tool-versions/mise.toml/CI OTP versions against erlang/otp releases; if unavailable, use build-failing placeholders (e.g. defaultless ARG OTP_VERSION), never remembered versions potentially predating named fixes.
  • In CI, read the full OTP version from filename:join([code:root_dir(), "releases", erlang:system_info(otp_release), "OTP_VERSION"]): erlang:system_info(otp_release) returns only the major. Fail when erlang/otp lists a newer OTP 27 release; lockfile audits miss runtimes.
  • Add Hex dependencies with newest hex.pm two-part requirements (~> MAJOR.MINOR, checked with mix hex.info <package>), admitting newer minors for latest-only fixes. Upgrade via mix deps.update <dep>/rebar3 upgrade <dep>; commit mix.lock/rebar.lock, pin Git commits, review source changes. If hex.pm is unreachable, report unverifiable versions and use build-failing placeholders, never remembered versions/lower bounds. Never lower/remove/loosen requirements, overrides, locks to pass resolution; report
