0.2.1 (2026-06-25)

REST core (GhEx.REST): get/post/patch/put/delete returning {:ok, body, meta} / {:error, reason}, and stream/3 for Link-header auto-pagination.
GraphQL core (GhEx.GraphQL): query/3 with variable passing and 200-with-errors normalization into GhEx.Error, and stream/4 for pageInfo cursor pagination.
Client and request plumbing: GhEx.new/1, GhEx.Client, GhEx.Request, with the required GitHub headers and bearer auth injected on every call.
Auth (GhEx.Auth): {:token, t} and {:app, issuer, pem} credential forms.
GitHub App auth: GhEx.JWT.mint/3 (OTP-native RS256, no JOSE dependency) and GhEx.App.installation_token/3 / installation_client/3 for one-shot installation access tokens.
Transparent installation-token caching: GhEx.App.installation/3 returns a client that mints, caches, and refreshes its token through a GhEx.TokenCache. GhEx.TokenCache.ETS is the default supervised cache (single-flight minting); the behaviour lets you plug in a clustered backend.
Metadata and errors: GhEx.REST.Meta, GhEx.GraphQL.Meta, GhEx.RateLimit, GhEx.Pagination, and the normalized GhEx.Error.
Convenience resources: GhEx.Issues and GhEx.PullRequests, thin wrappers over GhEx.REST for the common Issues and Pull Requests paths.
Opt-in GitHub-aware rate-limit retry: GhEx.RateLimit.retry/2, a Req-compatible policy that backs off on secondary rate limits (a 403 with retry-after or x-ratelimit-remaining: 0).
