## [2.1.2](https://github.com/rungalileo/galileo-js/compare/v2.1.1...v2.1.2) (2026-05-14)

### Bug Fixes

- **logStreamName:** Updated fields using previous format to logStreamName. ([#600](https://github.com/rungalileo/galileo-js/issues/600)) ([0bc6147](https://github.com/rungalileo/galileo-js/commit/0bc6147987f77be1d1b401f6a556b974568acde1))
- **utils:** Small refactoring to remove functions not exposed in equivalent Python SDK implementation. ([#590](https://github.com/rungalileo/galileo-js/issues/590)) ([9d7212a](https://github.com/rungalileo/galileo-js/commit/9d7212adb99f5993aa8c4cd61c8a281a4b67e492))

## Unreleased

### BREAKING CHANGES

- **singleton:** `init()`, `getLogger()`, `reset()`, `flush()` now accept `logStreamName` instead of `logstream`. This reverts the parameter renames introduced in PR #373 and restores consistency with `GalileoLoggerConfig.logStreamName`, `enableMetrics({ logStreamName })`, and the env var `GALILEO_LOG_STREAM_NAME`. The new name disambiguates the _name string_ from the `LogStream` entity. Callers must rename the property at call sites — no runtime fallback. OTel handler config (`GalileoOTLPExporterConfig.logstream`) and `GalileoSpanProcessor` are not affected by this change and remain on `logstream` until a separate follow-up.

### Bug Fixes

- **singleton:** `init()` now forwards `projectId` to `getLogger()` (previously dropped — latent bug).
