## [0.11.0] - 2026-05-07

### Documentation

- `AGENTS.md` — usage guide for AI coding assistants integrating PushX into
  projects: mental model (function-call API, no supervision-tree setup),
  decision tree (`push` / `push_batch` / `push_data` / instances), idiomatic
  patterns (token cleanup via `:on_invalid_token`, multi-tenant via
  `PushX.Instance`, web push topic IDs), and a curated list of mistakes
  commonly made (forgetting APNS `topic:`, `push_data` on APNS, mode
  mismatch, `fcm_credentials` as raw string, multiline `apns_private_key`
  via env). Shipped in the hex package and rendered on hexdocs.
- `CONTRIBUTING.md` — repo orientation for contributors: layout, test
  commands, conventions for error semantics and telemetry. `CLAUDE.md` is a
  symlink to `AGENTS.md` for tool compatibility.
- README banner pointing AI assistants at `AGENTS.md`.

### Fixed
- **APNS/FCM crash on transient Finch pool errors** — Finch's outer case in `lib/finch.ex:516` only matches `{:ok, …}` or the 3-tuple `{:error, err, _acc}` shape. When NimblePool returns a 2-tuple error — `{:error, :connection_process_went_down}` (HTTP/2 connection process death under concurrent-request-limit pressure) is the one observed in production, but the same pattern can produce other atom reasons — Finch raises `CaseClauseError` on itself. The exception escaped past `PushX.Retry`, killed the sending Task, and (in batch sends with caller-side `Enum.each`) silently skipped every recipient after the failing one. Now rescued in both `PushX.APNS` and `PushX.FCM`: any `CaseClauseError{term: {:error, reason}}` where reason is an atom is converted to a retryable `Response.error(_, :connection_error, _)`, so `PushX.Retry` handles reconnection normally. The previous narrow rescue only matched the literal `:connection_process_went_down` term and reraised any other 2-tuple shape.
- **APNS payload corruption when custom data uses an atom `:aps` key** — `Message.to_apns_payload/1`, `APNS.notification_with_data/4`, `APNS.silent_notification/1`, and `APNS.web_notification_with_data/5` previously stripped only the string `"aps"` key from caller data. A map containing both atom `:aps` and the constructed string `"aps"` was JSON-encoded with two `aps` keys, which APNS could reject or interpret unpredictably. All four functions now drop both `"aps"` and `:aps` from custom data.
- **APNS URL injection via unvalidated device tokens** — Device tokens were interpolated directly into the request URL (`/3/device/<token>`). A token containing `/`, `?`, `#`, or whitespace could redirect the request to an unintended path. `APNS.send/3`, `APNS.send_once/3`, and the named-instance APNS path now reject tokens that contain anything other than alphanumerics, underscore, or hyphen with `{:error, %Response{status: :invalid_token}}`.
- **`PushX.push_data/4` silently produced an invalid APNS payload for APNS named instances** — Calling `push_data(:my_apns_instance, …)` previously routed through `push/4` with a `%{"data" => …}` map, which APNS doesn't understand. Now rejected with `{:error, %Response{status: :invalid_request, provider: :apns}}` and a message pointing at `push/4` with `push_type: "background"` for APNS silent push.
- **JWT refresh could deadlock if the lock holder was killed** — The previous APNS JWT cache used `:atomics` as a mutex with `try/after` to release. If the holder was killed forcibly (e.g. `Process.exit(pid, :kill)`), the `after` clause did not run and every subsequent JWT request failed indefinitely with `"JWT refresh timeout after 10 attempts"`. The cache is now a supervised GenServer (`PushX.JWTCache`) with lock-free ETS reads and serialized refresh through `GenServer.call/3`. A killed refresher only delays callers until the supervisor restarts the process.
- **APNS empty-string `:topic` was forwarded to Apple** — Treating `""` as a valid topic produced a remote `MissingTopic` error. Both static and named-instance APNS paths now treat `nil` and `""` as missing and return `:invalid_request` locally.
- **Invalid APNS `:mode` raised `FunctionClauseError`** — A typo'd `apns_mode` (e.g. `:production`) crashed the sending Task past the `try/rescue` (which only catches `CaseClauseError`). Mode is now validated upfront and returns `{:error, %Response{status: :invalid_request}}` cleanly.
- **`push_batch/4` with `:validate_tokens` silently dropped invalid tokens** — Callers got a result list shorter than their input list with no signal of which tokens were skipped, so iterating in lockstep (e.g. to mark tokens) misaligned. Invalid tokens now get `{:error, %Response{status: :invalid_token, reason: "Invalid token format"}}` instead, so the result list always matches the input length. Same option is now honored by `APNS.send_batch/3` and `FCM.send_batch/3`.
- **`HTTP.stringify_map/1` raised `Protocol.UndefinedError` on nested maps/lists** — The previous `to_string(v)` worked only for binaries, atoms, and numbers. A nested map or list as an FCM `data` value crashed the calling process past the `try/rescue`. Nested maps and lists are now JSON-encoded so they survive transport as strings; PIDs and other non-stringable terms fall back to `inspect/1`.
- **`JSON.encode!` crashed the calling process on un-encodable terms** — A payload containing a PID, ref, function, or tuple raised past the rescue block (which only catches `CaseClauseError`). Encoding now goes through `PushX.HTTP.safe_encode/1`; failures return `{:error, %Response{status: :invalid_request, reason: "Failed to encode payload: ..."}}` cleanly. Encoding also happens before JWT/OAuth acquisition so an oversized or un-encodable payload doesn't waste a credential round-trip.
- **`push_batch/4` and `push_batch!/4` type specs missed instance names** — Both functions accept instance atoms but the spec was `provider() :: :apns | :fcm`. Dialyzer flagged legitimate calls. Specs now include `instance_name()`.
- **`Response.error(provider, …)` could embed an instance atom in the response struct** — `push_batch/4`'s `:exit, :timeout` branch used the caller-supplied provider atom directly, violating the `Response.provider :: :apns | :fcm | :unknown` typespec. Now mapped through `response_provider/1` so instance atoms collapse to `:unknown`.
- **`CircuitBreaker.record_failure/1` lost updates under concurrency** — `:ets.lookup` followed by `:ets.insert` is non-atomic, so concurrent failures undercounted and the real threshold was fuzzy. All circuit-breaker writes now route through the GenServer via `GenServer.call/2`, serializing them while reads stay lock-free.

### Added
- **Pre-flight payload size check** — APNS rejects payloads >4 KB (>5 KB for `push_type: "voip"`) and FCM rejects payloads >4 KB locally, returning `{:error, %Response{status: :payload_too_large}}` instead of round-tripping a guaranteed-fail request.
- **HTTP-date `Retry-After` parsing** — `HTTP.parse_retry_after/1` now handles RFC 1123 HTTP-date format (e.g. `"Wed, 21 Oct 2015 07:28:00 GMT"`) in addition to delta-seconds, per RFC 7231 §7.1.3. Falls back to `nil` (default backoff) for malformed or past dates.
- 25 new tests covering atom-`:aps` (3), URL-special characters (3), APNS-instance `push_data` guard (1), `JWTCache` GenServer (6), `:validate_tokens` error responses (3), empty `:topic` and unknown `:mode` (2), payload size and encode failures (2), and the `PushX.HTTP` module (5+ groups, 21 tests).
- Total test count: 340 tests, 25 doctests.

### Changed
- **Hot-path `Logger.debug` calls deferred** — APNS and FCM debug log lines now use the function form, so `PushX.Telemetry.truncate_token/1` no longer runs when debug logging is disabled. Measurable on high-volume batch sends.
- **Payload validation moved before credential acquisition** — APNS and FCM now encode + size-check the payload before requesting a JWT or OAuth token. Saves one ES256 signing or OAuth round-trip per rejected request and gives faster local error feedback.
- **Internal: shared HTTP helpers extracted** — `PushX.URLs` centralizes APNS/FCM endpoint constants and `PushX.HTTP` consolidates header parsing, `Retry-After` parsing, FCM `data` stringification, and JSON encoding. Eliminates ~100 lines of duplication between `PushX.APNS`, `PushX.FCM`, `PushX.Instance`, and `PushX.Application`.

## [0.10.0] - 2026-02-19

### Added
- **`PushX.push_data/3,4`** — Send data-only (silent) push notifications via both `:fcm` and named instances. Returns a clear error for `:apns` with guidance to use `push/4` with `push_type: "background"`.
- **`PushX.Response.extract_fcm_error_code/1`** — Public function to extract FCM-specific error codes from the `details` array in FCM v1 API responses. Eliminates duplicated parsing logic across modules.
- 16 new tests (8 for `extract_fcm_error_code`, 4 for FCM data-only/structured payloads, 3 for `push_data`, 1 for NOT_FOUND mapping)
- Total test count: 302 tests, 25 doctests

### Fixed
- **FCM UNREGISTERED errors parsed as unknown_error** — FCM v1 API wraps the real error code (e.g., `UNREGISTERED`) in a `details` array with `NOT_FOUND` as the top-level gRPC status. The parser only read the top-level status, so `on_invalid_token` callbacks never fired for unregistered tokens. Now extracts the FCM-specific `errorCode` from the details array. (Fixes #3)
- **FCM `build_message` always added notification key** — `build_message` hardcoded a `"notification"` key in the base map, making data-only messages impossible and sending `"notification": null` for empty Message structs. Now uses conditional logic to only include notification when content exists. (Fixes #2)
- **FCM structured payloads treated as notifications** — Raw maps with `"notification"` and/or `"data"` keys were wrapped in another `"notification"` key instead of being passed through. Now detects structured payloads and preserves their structure.

## [0.9.0] - 2026-02-16

### Added
- **Dynamic instances (runtime config)** — Start, stop, reconfigure, enable/disable APNS and FCM instances at runtime without application restart. Each instance gets its own HTTP/2 pool, JWT cache, and OAuth process. Enables database-backed admin panels for multi-provider setups. See [Dynamic Instances](README.md#dynamic-instances-runtime-config) in the README.
  - `PushX.Instance.start/3` — Start a named APNS or FCM instance
  - `PushX.Instance.stop/1` — Stop and clean up an instance
  - `PushX.Instance.reconfigure/2` — Hot-swap credentials or config without restart
  - `PushX.Instance.enable/1` / `disable/1` — Toggle instances without tearing down pools
  - `PushX.Instance.list/0` / `status/1` / `resolve/1` — Query running instances
  - `PushX.Instance.reconnect/1` — Restart an instance's HTTP/2 pool
  - `PushX.push/4` accepts instance names (e.g., `PushX.push(:apns_prod, token, msg, opts)`)
- **New response statuses** — `:invalid_request` (missing required options like `:topic`) and `:auth_error` (JWT/credential failure). Both are non-retryable and don't trip the circuit breaker.
- **Credential rotation docs** — README now documents how to hot-swap APNS/FCM credentials without restart for both static config and dynamic instances
- **HexDocs module groups** — Modules are now organized into Core API, Providers, Runtime Instances, Infrastructure, and Observability groups
- 45 new tests (Instance lifecycle, pool management, concurrent instances, error paths)
- Total test count: 286 tests, 23 doctests

### Fixed
- **APNS missing `:topic` no longer raises** — Returns `{:error, %Response{status: :invalid_request}}` instead of raising `ArgumentError`, consistent with the error-tuple API contract
- **JWT generation failure no longer crashes** — Returns `{:error, %Response{status: :auth_error}}` instead of raising, preventing process crashes from invalid private keys
- **JWT refresh no longer recurses infinitely** — Added depth limit (10 retries, 500ms max wait) to prevent stack overflow if the atomic lock holder crashes

### Changed
- `PushX.Response` provider type now includes `:unknown` for instance-not-found/disabled errors

## [0.8.0] - 2026-02-13

### Added
- **Circuit breaker** — Opt-in circuit breaker tracks consecutive failures per provider and temporarily blocks requests when a provider is consistently failing. Configurable threshold and cooldown. See [Circuit Breaker](README.md#circuit-breaker) in the README.
- **`PushX.health_check/0`** — Returns configuration status and circuit breaker state for each provider
- **Per-request timeout overrides** — Pass `:receive_timeout` and `:pool_timeout` as opts to individual `send` calls to override global config
- **Token cleanup callback** — Configure `on_invalid_token: {Mod, :fun, args}` to automatically clean up invalid tokens from your database
- `PushX.Telemetry.truncate_token/1` is now a public function for use in custom logging
- 23 doctests across 7 modules (Token, Telemetry, APNS, FCM, Message, Response, PushX)
- Circuit breaker test suite (13 tests)
- Integration tests for batch sending with mixed success/failure responses
- Total test count: 241 tests, 23 doctests

### Fixed
- **APNS payload injection** — Custom data containing an `"aps"` key can no longer overwrite the notification payload in `Message.to_apns_payload/1`, `notification_with_data/4`, `silent_notification/1`, and `web_notification_with_data/5`
- **FCM `send_data` parity** — `send_data/3` and `send_data_once/3` now have circuit breaker, telemetry, per-request timeouts, debug logging, and exception handling matching the regular `send/3` path
- **Reconnect error logging** — Retry logic now logs a warning if `PushX.reconnect/0` fails instead of silently ignoring the error
- **Device tokens redacted in debug logs** — APNS and FCM debug log messages now truncate tokens (first 8 + last 4 chars) matching the telemetry module's privacy behavior
- Fixed incorrect doctest for `Token.validate/2` (was `:invalid_format`, actually `:invalid_length`)

## [0.7.1] - 2026-02-11

### Added
- **Automatic pool reconnect on connection errors** — When the first retry attempt fails with a connection error (stale HTTP/2 connections), PushX now restarts the Finch pool to force fresh connections before retrying. This fixes the issue where retries on stale connections always fail with `too_many_concurrent_requests`.
- **`PushX.reconnect/0`** — Public function to manually restart the HTTP connection pool. Useful for recovering from persistent connection issues without restarting the app.
- **TCP keepalive on all connections** — Enables OS-level dead connection detection on APNS and FCM pools, helping prevent zombie HTTP/2 connections on cloud infrastructure.
- 4 new tests (reconnect, concurrent reconnect, retry-triggered reconnect, no reconnect on non-connection errors)
- Total test count: 219 tests

### Fixed
- Retries on stale HTTP/2 connections no longer fail repeatedly with `too_many_concurrent_requests` — the pool is recycled on first connection error

## [0.7.0] - 2026-02-09

### Fixed
- **FCM OAuth error handling** — `get_access_token/0` no longer raises on Goth failure, returns `{:ok, token} | {:error, reason}` instead
- **FCM data-only messages missing timeouts** — `send_data` now uses configured `receive_timeout` and `pool_timeout`
- **JWT cache thundering herd** — Added atomic compare-and-swap lock to prevent concurrent JWT refresh
- **Rate limiter O(n) scaling** — Replaced timestamp list with O(1) fixed-window counter in ETS
- **Batch timeout loses token identity** — Timed-out tokens now correctly reported via `Enum.zip`

### Changed
- **Rewritten README** — New structure with Quick Start, complete Usage Guide, and consolidated Configuration section
- Deprecated `request_timeout/0` (was never passed to Finch; use `receive_timeout` and `pool_timeout`)
- Fixed CHANGELOG FCM token validation range (was 100-500, actually 20-500)

## [0.6.2] - 2026-02-04

- Timeouts are now passed to Finch for both APNS and FCM requests
- Connection timeout configured at Finch pool level for better TCP handling
- **New logo** — Modern purple bell/arrow logo added to README and HexDocs

## [0.6.0] - 2026-02-04

### Changed
- **Increased default pool size** from 10 to 25 connections per pool
- **Increased default pool count** from 1 to 2 pools
- **Faster retry for connection errors** — connection errors now use 1s base delay (was 10s) since these are typically transient network issues, not provider throttling
- **Added explicit FCM HTTP/2 pool** — FCM endpoint now has dedicated HTTP/2 pool configuration (was using default pool)

### Added
- **Troubleshooting section** in README with solutions for common errors:
  - `too_many_concurrent_requests` — HTTP/2 stream limit exceeded
  - `request_timeout` — connection timeout issues
- **Pool sizing guide** in README with recommendations by traffic level
