-
-Stable releases are created about every 2 weeks. For the latest features and bug
-fixes, you can install the preview release. These releases receive the same
-level of testing as stable releases, but are not guaranteed to be available for
-more than 6 months after they are released. Once your application is stable, we
-recommend switching to stable releases.

-        Experimental API
-        ----------------
-
-        The optimization process is undergoing active development and may change.
-        Our goal with these changes is to improve the performance of optimization and
-        reduce the complexity.
-
-        That being said, it is essential today to run optimize if you want the best
-        performance.  It should be stable and safe to use in production, but it our
-        hope that the API may be simplified (or not even need to be called) in the
-        future.
-
-        The frequency an application shoudl call optimize is based on the frequency of
-        data modifications.  If data is frequently added, deleted, or updated then
-        optimize should be run frequently.  A good rule of thumb is to run optimize if
-        you have added or modified 100,000 or more records or run more than 20 data
-        modification operations.

-## Preview releases
-
-LanceDB has full releases about every 2 weeks, but in between we make frequent
-preview releases. These are released as `0.x.y.betaN` versions. They receive the
-same level of testing as normal releases and let you get access to the latest
-features. However, we do not guarantee that preview releases will be available
-more than 6 months after they are released. We may delete the preview releases
-from the packaging index after a while. Once your application is stable, we
-recommend switching to full releases, which will never be removed from package
-indexes.
-
-## Making releases
-
-The release process uses a handful of GitHub actions to automate the process.
