@ -22,31 +22,40 @@ As is traditional with a beta release, we do **not** recommend users install 3.0
* [CHANGE] Remove deprecated `remote-write-receiver`,`promql-at-modifier`, and `promql-negative-offset` feature flags. #13456, #14526
* [CHANGE] Remove deprecated `storage.tsdb.allow-overlapping-blocks`, `alertmanager.timeout`, and `storage.tsdb.retention` flags. #14640, #14643
* [FEATURE] Promtool: Allow additional labels to be added to blocks created from openmetrics. #14402
* [FEATURE] OTLP receiver: Add new option `otlp.promote_resource_attributes`, for any OTel resource attributes that should be promoted to metric labels. #14200
* [FEATURE] Automatic reloading of the Prometheus configuration file at a specified interval #14769
* [ENHANCEMENT] OTLP receiver: Warn when encountering exponential histograms with zero count and non-zero sum. #14706
* [ENHANCEMENT] Move AM discovery page from "Monitoring status" to "Server status". #14875
* [BUGFIX] Scrape: Do not override target parameter labels with config params. #11029
## 2.55.0-rc.0 / 2024-09-20
* [FEATURE] Support UTF-8 characters in label names - feature flag `utf8-names`. #14482, #14880, #14736, #14727
* [FEATURE] Support config reload automatically - feature flag `auto-reload-config`. #14769
* [FEATURE] Scraping: Add the ability to set custom `http_headers` in config. #14817
* [FEATURE] Scraping: Support feature flag `created-timestamp-zero-ingestion` in OpenMetrics. #14356, #14815
* [FEATURE] Scraping: `scrape_failure_log_file` option to log failures to a file. #14734
* [FEATURE] OTLP receiver: Optional promotion of resource attributes to series labels. #14200
* [FEATURE] Remote-Write: Support Google Cloud Monitoring authorization. #14346

* [ENHANCEMENT] OTLP receiver: Interrupt translation on context cancellation/timeout. #14612
* [ENHANCEMENT] Scrape: Only parse created timestamp if `created-timestamp-zero-ingestion` feature flag is enabled. This is as a lot of memory is used when parsing the created timestamp in the OM text format. #14815
* [ENHANCEMENT] Scrape: Add support for logging scrape failures to a specified file. #14734
* [ENHANCEMENT] Remote Read client: Enable streaming remote read if the server supports it. #11379

* [BUGFIX] TSDB: Fix shard initialization after WAL repair. #14731

* [BUGFIX] Native Histograms: Do not re-use spans between histograms. #14771
* [BUGFIX] Scrape: Only parse created timestamp if `created-timestamp-zero-ingestion` feature flag is enabled. This is as a lot of memory is used when parsing the created timestamp in the OM text format. #14815
* [BUGFIX] TSDB: Fix panic in query during truncation with OOO head. #14831
