Issues fixed Copied

These are the issues we have fixed in this release:

Issue key Release description
HP-1595 The entity stream now enforces a limit (500 by default) to the number of distinct signals that can be attached to a single entity. Once the limit is exceeded, signals continue being processed but the entity’s severity is no longer updated and the entity is marked with an events-partially-applied attribute. The attribute gets cleared and the entity’s severity updates again once the number of open signals for the entity drops back under the clearing limit (300 by default).
HP-2253 Fixed an issue where GetMetricMetadata did not correctly match the none unit.
HP-2260 Fixed an issue causing some signals created in short sequence via the API to be discarded by the entities subsystem, which led to an inconsistency between entity severities and signals timelines.
HP-2264 Upgrade Keycloak to version 23.0.4 to resolve CVE-2023-6134.
HP-2270 The configuration installer now handles conflict with custom entity containment rules during upgrades.
HP-2275 Styles are now correctly loaded on the Keycloak login page.

HP-2278 Fixed unit normalization in DPD.
HP-2294 Deployment no longer fails to complete when using downsampledMetricsStream.storeRetention with minimum config.
HP-2310 Fixed an issue where, under certain conditions, some entities would remain active forever, preventing them from being evicted.
