d0f3a8b: logFilter.accessLine hides the access line for paths matching exclude or not matching include, so health checks and metrics scrapes stop writing a line per probe. Responses at 400 or above, thrown errors and a handler’s own log lines are never hidden.
666861e: Adapters and withRedaction accept an onDropped callback that reports how many records were lost and why, so you can keep a running count of dropped logs.
bb7946c: aiMiddleware(log) from logixlysia/ai records AI SDK usage with one wrapLanguageModel line, streams included. A call that finishes after the request’s line was written, as toTextStreamResponse() does, writes an ai call finished line, so its usage still reaches your sinks. mergeAIMetrics also accepts the handler’s log directly: mergeAIMetrics(log, metrics).
ab89c27: Head sampling now rolls once per request, so a request’s records are kept or dropped together. A sampled app keeps close to the configured share of requests, where an access line used to get a second chance after its custom log was dropped, so counts may fall.
a850609: mergeContext and per-line context now merge nested plain objects, so log.mergeContext({ user: { id } }) followed by log.mergeContext({ user: { plan } }) keeps both keys. A nested overwrite that relied on replacing the whole object now keeps the old keys; send null or an array to replace (a typed field’s type has to allow it). Arrays, dates and class instances still replace, and typed fields accept a partial nested object through the new DeepPartial type.
7425808: log.error(err) accepts whatever you caught, so catch (err) { log.error(err) } compiles and logs the error. A non-string is serialized like a thrown error, with its name, HttpError fields and cause, instead of a blank message. The line carries no status, since the handler may recover.
71b77c8: logixlysia/http exports createHttpTransport, so a backend without a built-in adapter gets the same batching, retries, bounded queue and onDropped by supplying a URL, headers and a request body.
64508cb: redactPatterns masks custom value shapes, such as a customer id, in log strings, URL path segments, query values and header values when autoRedact is on.
7abac9d: plugin.runJob(name, fn) runs a cron job, queue consumer or script outside a request and writes one final JOB line for it, with duration, outcome and accumulated context, through every sink. It returns fn’s value, logs a thrown error with status 500 and rethrows it, and makes useLogger() work inside fn without useAsyncLocalStorage.
d0f3a8b: sampling.tail.keep takes a predicate that receives the finished request’s durationMs, pathname, status and context, so tail sampling can rescue by anything the handler learned. A predicate that throws counts as no match and is reported through onError with sink: 'sampling'. RequestOutcome gains a required context field.
26ab23b: A transport can set minLevel to receive only records at that level or louder, so you can send errors to Sentry and everything to Axiom without a wrapper. Every adapter accepts the option, and withRedaction keeps it.
399797c: Error lines sent to transports now include error.stack, unless the error’s own status is below 500.
d0f3a8b: FormattingConfig, OutputConfig, PinoConfig, PrettyPrintConfig, RedactionConfig and RequestTrackingConfig can now be imported from logixlysia, so a wrapper around the config can name them.
7abac9d: WebSocket lifecycle lines are labelled WS as documented, not GET.
