## Minor Changes

- 64333ca: `logRotation.interval` now actually rotates. The live file's age (from
  filesystem creation time, falling back to open time where the filesystem
  reports none) is checked after every write, and the file rotates on the
  first write after the interval elapses — no timers, so an idle process
  rotates on its next write rather than on a wall-clock schedule. When both
  `maxSize` and `interval` are set, whichever trigger is crossed first
  rotates. Previously `interval` was accepted and format-validated but
  never triggered rotation; configs that already set it will begin rotating
  on upgrade.
- 964e60c: `autoRedact` now redacts by sensitive key/header names (authorization, cookie, x-api-key, password, secret, token, session, …) in addition to value patterns; new `config.redactKeys` extends the list, and pino gets matching `redact.paths` defaults.
- 1e949a1: Harden log output: file-sink lines, client IPs, and context-tree values are sanitized (control characters escaped/stripped, lengths bounded); malformed inbound request IDs are replaced with generated ones; log files/dirs are created with `0600`/`0700` modes, configurable via `logFileMode`/`logDirMode` (existing files keep their mode).
- 3267e1f: Internal log/error pipelines are unified: error-path logs now honor the same sink gates and console-method-by-level as success-path logs (a 4xx warning now prints via `console.warn` instead of `console.error`). New `config.onError` hook surfaces transport/file/rotation sink failures to your code.
- 11a0cd2: Validation errors no longer log the submitted request body (`found`/`errors`) by default — messages are normalized to the failed paths only. Set `config.logErrorPayload: true` to restore payload logging. Raw Error objects are no longer passed into transport meta.

## Patch Changes

- efab720: File sink now holds an open file handle, batches same-tick lines into single writes, creates the log directory once, and tracks file size in memory — removing the per-line mkdir/open/stat syscalls. Rotation behavior is unchanged.
- 69b83aa: Per-request logging is faster: format tokens are computed only when present in the log format, colors/thresholds/service are resolved once per logger, URL parsing and duration sampling happen once per emission, internal context reads no longer clone, WebSocket synthetic requests are memoized per path, and `autoRedact` returns the original object untouched when nothing needs redacting.
- ad0a2e6: pino is now constructed lazily on first access to `store.pino`/`logger.pino` (or eagerly when `config.pino` is set), instead of on every plugin instantiation. Dead internal helpers `formatLine`, `logWithPino`, and `renderContextTreeLines` were removed (they were never exported from the package).
- 6c26cc2: Remove the unused `ai` peer dependency, mark `typescript` as an optional peer and widen it to the proven TS 5.x floor, and align the package tsconfig with the shared monorepo base.
- 30869f4: Internal type reorganization: the config object is now composed of named sub-interfaces (`FormattingConfig`, `OutputConfig`, `RedactionConfig`, …) behind the same `Options` shape; `HttpError` moved to a dedicated module. All public import paths and names are unchanged.

## Correction (2026-08-10)

The 5.3.0 entries "log-rotation: implement complete rotation with
interval support" (673b800, 9016a51) added the `interval` config field
and its format validation, but did not wire it to actually trigger
rotation — `interval` was a no-op from 5.3.0 until the lazy-on-write
implementation landed on 2026-08-10. See
`plans/spikes/021-interval-rotation-decision.md` for the investigation.
