+title: "Introducing the previsional Release Roadmap"
+authors: Antoine Colombier
+tags: development, improvements
+slug: Previsional-Release-Roadmap
+date: 2024-09-22 12:00:00
+
+As of today, we have just introduced a [Previsional Release Roadmap](/release_roadmap) page on the website which will help you keeping track on when to expect new Mixxx releases, with a focus on new minor releases, which are the release containing all the new shiny features that the community is working hard to deliver.
+
+Mixxx is adopting a 6-month development cycle, starting from the soon to come 2.5.0. Going forward, you should expect new release every October and April of each years, similarly to the Ubuntu release cycle. Note that this is only a guideline for the team to know on when to focusing on making a release, but quality will remain the main driver as well as depending on available of the team to complete the release process.

+  <h1>Previsional Release Roadmap</h1>
+
+  <p>
+    This document helps providing visibility. Starting from release 2.5, Mixxx is following <a href="https://github.com/mixxxdj/mixxx/wiki/250_release_proposal#proposal-1-phase-model" target="_blank">a 6-month development cycle</a>. This means that every 6 month, a new minor version is released, with the latest 6-month worth of feature, which may vary depending of the community involvement.
+  </p>
+  <p>
+    This way of working aim to reduce the time it takes for a contributor to see the feature they've worked on being release, while also allowing the Mixxx Core Team not to spend too much time on new release admin tasks.
