Here&rsquo;s a summary of new enhancements and important fixes:</p> <h2 id="features-and-enhancements">Features and enhancements</h2> <ul> <li><strong>TSDB index no longer experimental</strong> After extensive testing of the new TSDB index in our Grafana Cloud Logs offering, we can safely announce that it is no longer experimental and encourage all Loki deployments to use it!</li> <li><strong>Query blocker</strong> Queries can now be blocked in the Querier/Ruler via a per-tenant runtime configuration.</li> <li><strong>New <code>backend</code> target</strong> A new, third target was added to Loki&rsquo;s <em>scalable</em> configuration, which is the default configuration used in the Loki helm chart. This allows Loki to be run as 3 targets (<code>read</code>, <code>write</code>, and <code>backend</code>) and makes the <code>read</code> target stateless and therefore able to be run as a Kubernetes deployment that can be scaled automatically.</li> </ul> <p>For a full list of all changes, look at the <a href="https://github.com/grafana/loki/blob/release-2.8.x/CHANGELOG.md" target="_blank" rel="noopener noreferrer">CHANGELOG</a>.</p>https://grafana.com/docs/loki/v3.7.x/release-notes/v2-7/Thu, 09 Apr 2026 02:28:18 +0000https://grafana.com/docs/loki/v3.7.x/release-notes/v2-7/<h1 id="v27">V2.7</h1> <p>Grafana Labs is excited to announce the release of Loki 2.7. Here&rsquo;s a summary of new enhancements and important fixes:</p> <h2 id="features-and-enhancements">Features and enhancements</h2> <ul> <li><strong>New Internal Server and TLS</strong> TLS can now be configured everywhere and there is an internal server to allow ring, memberlist, and readiness handlers to continue to work without TLS.</li> <li><strong>Better Support for Azure Blob Storage</strong> thanks to the ability to use Azure&rsquo;s Service Principal Credentials.</li> <li><strong>Logs can now be pushed from the Loki canary</strong> so you don&rsquo;t have to rely on a scraping service to use the canary.</li> <li><strong>Additional <code>label_format</code> fields</strong> <code>__timestamp__</code> and <code>__line__</code>.</li> <li><strong><code>fifocache</code> has been renamed</strong> The in-memory <code>fifocache</code> has been renamed to <code>embedded-cache</code>. Check <a href="../../setup/upgrade/#270">upgrade guide</a> for more details</li> <li><strong>New HTTP endpoint for Ingester shutdown</strong> that will also delete the ring token.</li> <li><strong>Faster label queries</strong> thanks to new parallization.</li> <li><strong>Introducing Stream Sharding</strong> an experimental new feature to help deal with very large streams.</li> <li><strong>Promtail</strong> <ul> <li>support for max stream limit</li> <li>config reload endpoint / signal</li> <li>compressed file support</li> <li><code>lambda-promtail</code> now supports Kinesis data stream events</li> <li>matches for the journal reader</li> <li>basic tracing support</li> </ul> </li> </ul> <p>For a full list of all, look at the <a href="https://github.com/grafana/loki/blob/main/CHANGELOG.md" target="_blank" rel="noopener noreferrer">CHANGELOG</a>.</p>https://grafana.com/docs/loki/v3.7.x/release-notes/v2-6/Thu, 09 Apr 2026 02:28:18 +0000https://grafana.com/docs/loki/v3.7.x/release-notes/v2-6/<h1 id="v26">V2.6</h1> <p>Grafana Labs is excited to announce the release of Loki 2.6. Here&rsquo;s a summary of new enhancements and important fixes.</p> <h2 id="features-and-enhancements">Features and enhancements</h2> <ul> <li><strong>Query multiple tenants at once.</strong> We&rsquo;ve introduced cross-tenant query federation, which allows you to issue one query to multiple tenants and get a single, consolidated result. This is great for scenarios where you need a global view of logs within your multi-tenant cluster. For more information on how to enable this feature, see <a href="../../operations/multi-tenancy/">Multi-Tenancy</a>.</li> <li><strong>Filter out and delete certain log lines from query results.</strong> This is particularly useful in cases where users may accidentally write sensitive information to Loki that they do not want exposed. Users craft a LogQL query that selects the specific lines they&rsquo;re interested in, and then can choose to either filter out those lines from query results, or permanently delete them from Loki&rsquo;s storage. For more information, see <a href="../../operations/storage/logs-deletion/">Logs Deletion</a>.</li> <li><strong>Improved query performance on instant queries.</strong> Loki now splits instant queries with a large time range (for example, <code>sum(rate({app=&quot;foo&quot;}[6h]))</code>) into several smaller sub-queries and executes them in parallel. Users don&rsquo;t need to take any action to enjoy this performance improvement; however, they can adjust the number of sub-queries generated by modifying the <code>split_queries_by_interval</code> configuration parameter, which currently defaults to <code>30m</code>.</li> <li><strong>Support Baidu AI Cloud as a storage backend.</strong> Loki users can now use Baidu Object Storage (BOS) as their storage backend. See <a href="/docs/loki/v3.7.x/configure/">bos_storage_config</a> for details.</li> </ul> <p>For a full list of all changes, look at the <a href="https://github.com/grafana/loki/blob/main/CHANGELOG.md" target="_blank" rel="noopener noreferrer">CHANGELOG</a>.</p>https://grafana.com/docs/loki/v3.7.x/release-notes/v2-5/Thu, 09 Apr 2026 02:28:18 +0000https://grafana.com/docs/loki/v3.7.x/release-notes/v2-5/<h1 id="v25">V2.5</h1> <p>It has been nearly 6 months since Loki 2.4 was released, and we’ve been busy making Loki better than ever. Here&rsquo;s a summary of new enhancements and important fixes.</p>https://grafana.com/docs/loki/v3.7.x/release-notes/v2-4/Thu, 09 Apr 2026 02:28:18 +0000https://grafana.com/docs/loki/v3.7.x/release-notes/v2-4/<h1 id="v24">V2.4</h1> <p>Loki 2.4 focuses on two items:</p> <ul> <li>Making it easier to get your logs into Loki.</li> <li>Making Loki easier to run and operate. Anyone not using Kubernetes or avoiding microservices should pay close attention: this release has a lot for you.</li> </ul> <h2 id="features-and-enhancements">Features and enhancements</h2> <ul> <li> <a href="/docs/loki/v3.7.x/configure/#accept-out-of-order-writes"><strong>Loki no longer requires logs to be sent in perfect chronological order.</strong></a> Support for out of order logs is one of the most highly requested features for Loki. The strict ordering constraint has been removed.</li> <li>Scaling Loki is now easier with a hybrid deployment mode that falls between our single binary and our microservices. The <a href="../../get-started/deployment-modes/">Simple scalable deployment</a> scales Loki with new <code>read</code> and <code>write</code> targets. Where previously you would have needed Kubernetes and the microservices approach to start tapping into Loki’s potential, it’s now possible to do this in a simpler way.</li> <li>The new <a href="/docs/loki/v3.7.x/configure/#common"><code>common</code> section</a> results in a 70% smaller Loki configuration. Pair that with updated defaults and Loki comes out of the box with more appropriate defaults and limits. Check out the <a href="https://github.com/grafana/loki/blob/main/cmd/loki/loki-local-config.yaml" target="_blank" rel="noopener noreferrer">example local configuration</a> as the new reference for running Loki.</li> <li><a href="../../alert/#recording-rules"><strong>Recording rules</strong></a> are no longer an experimental feature. We&rsquo;ve given them a more resilient implementation which leverages the existing write ahead log code in Prometheus.</li> <li>The new <a href="../../send-data/promtail/scraping/#kafka"><strong>Promtail Kafka Consumer</strong></a> can easily get your logs out of Kafka and into Loki.</li> <li>There are <strong>nice LogQL enhancements</strong>, thanks to the amazing Loki community. LogQL now has <a href="../../query/#many-to-one-and-one-to-many-vector-matches">group_left and group_right</a>. And, the <code>label_format</code> and <code>line_format</code> functions now support <a href="../../query/template_functions/#now">working with dates and times</a>.</li> <li>Another great community contribution allows Promtail to <a href="../../send-data/promtail/configuration/#loki_push_api"><strong>accept ndjson and plaintext log files over HTTP</strong></a>.</li> </ul> <p>All in all, about 260 PR’s went into Loki 2.4, and we thank everyone for helping us make the best Loki yet.</p>https://grafana.com/docs/loki/v3.7.x/release-notes/v2-3/Thu, 09 Apr 2026 02:28:18 +0000https://grafana.com/docs/loki/v3.7.x/release-notes/v2-3/<h1 id="v23">V2.3</h1> <p>The Loki team is excited to announce the release of Loki 2.3!</p> <p>It&rsquo;s been nearly 6 months since 2.2 was released and we have made good use of that time to bring forward several significant improvements and requested features.</p>
