On behalf of the OpenBao TSC and Development Working Group, I'm happy to announce the 2.0.0 Beta release is available now!

Major improvements include:

- Fixing compatibility with existing upstream plugins. - Fixing migration from upstream 1.14.0 release w.r.t. SSCT token support. - Alternative release pipeline and improvements for release distribution.

Many thanks to the community for making this release possible and all the contributions!

The GA release is currently slated for release four weeks from now on July 16th, 2024. Prior to this, the focus will be on stability of the GA release. Feel free to open issues or discussions on GitHub: https://github.com/openbao/openbao/
