# Changelog # Changelog
## 9.0.1 ## 10.0.0
Released 2020-mm-dd Released 2020-mm-dd
Breaking changes:
- Log system revamp:
- Logs to stdout, disabled while testing
- Upgrade `camshaft` to version [`0.x.0`](https://github.com/CartoDB/camshaft/releases/tag/0.x.0)
- Use header `X-Request-Id`, or create a new `uuid` when no present, to identyfy log entries
- Be able to set log level from env variable `LOG_LEVEL`, useful while testing: `LOG_LEVEL=info npm test`; even more human-readable: `LOG_LEVEL=info npm t | ./node_modules/.bin/pino-pretty`
- Stop responding with `X-Tiler-Errors` header. Now errors are properly logged and will end up in ELK as usual.
- Stop responding with `X-Tiler-Profiler` header. Now profiling stats are properly logged and will end up in ELK as usual.
- Be able to reduce the footprint in the final log file depending on the environment
- Be able to pass the logger to the analysis creation (camshaft) while instantiating a named map with analysis.
- Be able to tag requests with labels as an easier way to provide business metrics
- Metro: Add log-collector utility (`metro`), it will be moved to its own repository. Attaching it here fro development purposes. Try it with the following command `LOG_LEVEL=info npm t | node metro`
- Metro: Creates `metrics-collector.js` a stream to update Prometheus' counters and histograms and exposes them via Express' app (`:9145/metrics`). Use the ones defined in `grok_exporter`
Bug Fixes: Bug Fixes:
- While instantiating a map, set the `cache buster` equal to `0` when there are no affected tables in the MapConfig. Thus `layergroupid` has the same structure always: - While instantiating a map, set the `cache buster` equal to `0` when there are no affected tables in the MapConfig.

- `${map_id}:${cache_buster}` for anonymous map - `${map_id}:${cache_buster}` for anonymous map
