Key features in Loki 3.3.0 include the following:

- **Query acceleration with Bloom filters** (experimental): The Bloom filters feature introduced in Loki 3.0 remains experimental. There has been a major shift in how Loki leverages bloom filters — pivoting from free-text search to harnessing the power of structured metadata ([#14061](https://github.com/grafana/loki/issues/14061)) ([a2fbaa8](https://github.com/grafana/loki/commit/a2fbaa8e09b6eebff2f7c20746e84f1365bd7433)). This change leverages the growing adoption of OpenTelemetry in observability stacks. The Bloom Compactor component has been removed and replaced by the Bloom Planner and Bloom Builder components ([#13997](https://github.com/grafana/loki/issues/13997)) ([bf60455](https://github.com/grafana/loki/commit/bf60455c8e52b87774df9ca90232b4c72d72e46b)) and blooms has a new block schema (V3) ([#14038](https://github.com/grafana/loki/issues/14038)) ([5395daf](https://github.com/grafana/loki/commit/5395daf898c2d0bbc4756ab6260c54feda960911)) which is a breaking change.

- **Explore Logs:** Starting with Grafana v11.3, the plugin for the Explore Logs app is installed in Grafana by default. This release includes enhancements to improve pattern ingester tracing ([#14707](https://github.com/grafana/loki/issues/14707)) ([80aec25](https://github.com/grafana/loki/commit/80aec2548203957dbb834ba69e6d734d9054416d)), to apply patterns line length limit to json message keys ([#14296](https://github.com/grafana/loki/issues/14296)) ([41fafd8](https://github.com/grafana/loki/commit/41fafd87933224d5d43592e91e339322fc90a466)), add configuration to set `max-allowed-line-length` in the pattern ingester ([#14070](https://github.com/grafana/loki/issues/14070)) ([0780456](https://github.com/grafana/loki/commit/0780456662b67edde69004cf4ee3873c23d5094b)) and move metric aggregation to a per-tenant configuration ([#14709](https://github.com/grafana/loki/issues/14709)) ([c1fde26](https://github.com/grafana/loki/commit/c1fde26730b4fc54e4bbc724d1b29f653541f720)).
