0.1.1 - 2026-08-20

Docker build scripts (docker/erlang, docker/elixir) and READMEs for building the lambda-layer-erlang and lambda-layer-elixir images that mix aws_lambda.build pulls from.
mix aws_lambda.build — --dep/-d flag to install extra dnf packages (e.g. git) in the build container alongside tar.

mix aws_lambda.build — colorized, more consistent step output; internal cleanup.

AWS.Lambda.Runtime.MixRelease (priv/mix/release.exs) — the release steps it configured are documented directly in the README instead.

AWS.Lambda.Runtime — the custom runtime loop: long-polls the Lambda Runtime API, dispatches each invocation to your handler within a supervised, deadline-bounded task, and reports the result or failure back to Lambda without crashing the sandbox.
AWS.Lambda.Runtime.API — a dependency-free :inets/:httpc client for the Lambda Runtime API (2018-06-01).
AWS.Lambda.Runtime.Context — per-invocation context assembled from the Lambda-Runtime-* response headers and the function's environment.
AWS.Lambda.Runtime.Handler — the behaviour your function implements, plus resolution of the _HANDLER environment variable / compile-time config.
AWS.Lambda.Runtime.Application — the OTP application supervising the runtime loop, with a config :aws_lambda_runtime, start_runtime: false escape hatch for environments (like this library's own test suite) that shouldn't start it.
AWS.Lambda.Runtime.MixRelease and AWS.Lambda.Runtime.Release — mix release configuration and steps that package a function for Lambda's provided.al2023 runtime, including the bootstrap entrypoint and Lambda-tuned vm.args/env.sh.
mix aws_lambda.build — packages a function's Lambda release inside the Elixir builder Docker image and downloads the resulting deployment zip.
