+# v3.4
+
+Grafana Labs and the Loki team are excited to announce the release of Loki 3.4. Here's a summary of new enhancements and important fixes.
+
+For a full list of all changes and fixes, refer to the [CHANGELOG](https://github.com/grafana/loki/blob/release-3.4.x/CHANGELOG.md).
+
+## Features and enhancements
+
+Key features in Loki 3.4.0 include the following:
+
+- **Time sharding ingestion:** Add per-tenant time sharding for long out-of-order ingestion. The setting `shard_streams.time_sharding_enabled` is a per-tenant config that splits incoming log streams by injecting a new `__time_shard__` synthetic label in such a way that no stream will ever be longer than `1h` (or, rather, `max_chunk_age`/2). This allows the ingestion of very old logs, because the logs in these new streams will never be "too far behind" by design. ([#14711](https://github.com/grafana/loki/issues/14711)) ([0d6d68d](https://github.com/grafana/loki/commit/0d6d68d9bfd145164e48718c794c50cea5de02fa)).
+
+- **Thanos object client:** Previously Loki and Grafana Enterprise Logs used different Go packages to talk to the underlying object store. Migrating to Thanos means that there is now a single object client across Loki and GEL, and across the other Grafana backend databases: Mimir and Pyroscope.([#14891](https://github.com/grafana/loki/issues/14891)) ([fb6789d](https://github.com/grafana/loki/commit/fb6789d9df1b76aa8fb08b6e9db951a6f7e93aae)), ([#14638](https://github.com/grafana/loki/issues/14638)) ([8958eb9](https://github.com/grafana/loki/commit/8958eb91eda56a5334d0bdb683a9fb592cd5d17e)), ([#14867](https://github.com/grafana/loki/issues/14867)) ([947a66f](https://github.com/grafana/loki/commit/947a66f35e1e02505290f52f2eee17c3e281cbbc)), ([#14793](https://github.com/grafana/loki/issues/14793)) ([cfc3819](https://github.com/grafana/loki/commit/cfc38194b46711c23c84bbb52cf1f11e6db99bda)), ([#14937](https://github.com/grafana/loki/issues/14937)) ([a629212](https://github.com/grafana/loki/commit/a629212ceba6bde476995c0550216f0431fb380b)). The documentation now includes [configuration examples](https://grafana.com/docs/loki/<LOKI_VERSION>/configure/examples/thanos-storage-configs/) using Thanos-based storage clients.
+
+- **API:** Add support for [Parquet file format](https://parquet.apache.org/docs/file-format/) as a query response format. ([#15408](https://github.com/grafana/loki/issues/15408)) ([d0c11a6](https://github.com/grafana/loki/commit/d0c11a689e7835628259f845cd41da818c7e1e18)).
+
+- **Structured metadata:** Introduces a new feature,based on per-tenant configuration, that allows for extraction of "fields" into structured metadata at ingest time. Fields can either be regular labels, structured metadata keys, or keys from `logfmt` or `json` formatted log lines. ([#15188](https://github.com/grafana/loki/issues/15188)) ([7033091](https://github.com/grafana/loki/commit/7033091bc9f60505e1492779c91f0d0c0e42dfc7)).
+
+- **lambda-promtail:** Adds support for relabeling log entries in lambda-promtail using Prometheus-style relabel configs. This allows for more flexible label manipulation and filtering of log entries before they are sent to Loki. ([#15600](https://github.com/grafana/loki/issues/15600)) ([c41a8b4](https://github.com/grafana/loki/commit/c41a8b4b9b57cfc98445992ecab0b6378e831e03)).
+
+- **Kafka:** Loki 3.4 adds an Apache Kafka development environment to support ongoing development work([#15603](https://github.com/grafana/loki/issues/15603)) ([226e9f1](https://github.com/grafana/loki/commit/226e9f101aab2faf32b2d6b0c93f6e5832782c25)).
+
+- **Helm charts:** Loki 3.4 includes multiple improvements to the Helm charts, including: Added support for overrides exporter ([#15630](https://github.com/grafana/loki/issues/15630)) ([db72164](https://github.com/grafana/loki/commit/db72164215280b8b47780036ca866f065e681f60)), Expose topologySpreadConstraints for admin-api pods ([#14995](https://github.com/grafana/loki/issues/14995)) ([1b93086](https://github.com/grafana/loki/commit/1b93086a2082ec18a8f766dec7778b04e991ba10)), Expose topologySpreadConstraints for distributed deployment ([#14853](https://github.com/grafana/loki/issues/14853)) ([d075107](https://github.com/grafana/loki/commit/d0751071a4db971788c93f89a1add97887cb2e6d)), Compute ConfigMap/Secret checksum only over .data content ([#15177](https://github.com/grafana/loki/issues/15177)) ([990f71c](https://github.com/grafana/loki/commit/990f71c5e90a1b9921820ac06555b9ecd1a6539c)), Do not explicitly template `managed-by`, as it should be set at install time by the installation manager. ([#14763](https://github.com/grafana/loki/issues/14763)) ([10b7478](https://github.com/grafana/loki/commit/10b74781cf17b4df13815a4aa4ab0f9b17da5216)).
+
+- **Query acceleration with Bloom filters (experimental)**: The Bloom filters feature introduced in Loki 3.0 remains experimental. In Loki 3.3, there was a major shift in how Loki leverages bloom filters — pivoting from free-text search to harnessing the power of structured metadata. In Loki 3.4, work continues on the new Bloom Planner ([#14874](https://github.com/grafana/loki/issues/14874)) ([b646861](https://github.com/grafana/loki/commit/b646861e770e6903538bb22dd551686aaeb7349d)).
+
+- **Docs:** This release includes a heavily revised [labels topic](https://grafana.com/docs/loki/<LOKI_VERSION>/get-started/labels/) and a new [Cardinality topic](https://grafana.com/docs/loki/<LOKI_VERSION>/get-started/labels/cardinality/). This release also marks the return of the [sizing guidance page](https://grafana.com/docs/loki/latest/setup/size/), newly updated based on Grafana Labs experience running Loki. Continuing updates to the Query section include a revised [logcli topic](https://grafana.com/docs/loki/latest/query/logcli/getting-started/) and new [logcli tutorial](https://grafana.com/docs/loki/latest/query/logcli/logcli-tutorial/). There is also two additional new tutorials: [Deploying Loki on Azure tutorial](https://grafana.com/docs/loki/latest/setup/install/helm/deployment-guides/azure/) and [Kubernetes Monitoring Helm tutorial](https://grafana.com/docs/loki/latest/send-data/k8s-monitoring-helm/).

+## Deprecations
+
+One of the focuses of Loki 3.0 was cleaning up unused code and old features that had been previously deprecated but not removed. Loki 3.0 removed a number of previous deprecations and introduces some new deprecations. Some of the main areas with changes include:
+
+- [Promtail](https://grafana.com/docs/loki/<LOKI_VERSION>/send-data/promtail/) is deprecated, as the code has been merged into Grafana Alloy. You can find migration documentation and a utility to convert your Promtail configuration to Alloy configuration in the [Alloy documentation](https://grafana.com/docs/alloy/latest/set-up/migrate/from-promtail/).
+
+- [Deprecated storage options](https://grafana.com/docs/loki/<LOKI_VERSION>/storage/) including the deprecation of the BoltDB store.
+
+- [Deprecated configuration options](https://grafana.com/docs/loki/<LOKI_VERSION>/configure/).
+
+- [API endpoint deprecations](https://grafana.com/docs/loki/<LOKI_VERSION>/reference/api/#deprecated-endpoints).
+
+To learn more about breaking changes in this release, refer to the [Upgrade guide](https://grafana.com/docs/loki/<LOKI_VERSION>/setup/upgrade/).
