Highlights
- 1.3.x Deprecation: Support for the 1.3.x version will end in 2025.
- 2.19.x Maintenance Mode: The 2.19.x version will enter maintenance mode, with patch version released between every two 3.x releases with a quarterly release schedule.
- 3.x Major Release: The 3.0.0 major version will be released alongside Lucene 10. We will release minor updates for the 3.x line follows a 8-week cadence.
We believe this schedule will allow us to deliver high-quality updates while maintaining a predictable cadence for the community. Additionally, it provides the team with more time to fine-tune releases and improve their overall quality.
This will also address issues like overlapping release windows, reduce the strain on the infra team, and give feature teams more time to complete significant features without frequent interruptions.
Please share your feedback in the comments.
Thanks!
