Request: cut a new release from main #319

Hi,

The last tagged release, v0.3.0, dates back to September 2024, and main has accumulated around 120 commits since then (v0.3.0...main).

Several of them are changes we would like to run in production, but we would rather not deploy a build from an untagged commit:

• SPNEGO authentication support (Support SPNEGO authentication method #307)
• Support for multiple CAs in TLS (feat(server/tls): add support for multiple CAs  #310)
• Reworked subscription filters (PrincsFilter to ClientFilter reimplementation #186)
• Optional Prometheus metrics endpoint (Optionally expose usage metrics #190)
• Dependency upgrades fixing RustSec advisories (fix(deps): upgrade dependencies to resolve RustSec advisories #314)

The Unreleased section of the CHANGELOG already covers most of this, so the groundwork seems to be there. Would it be possible to publish a new release, so that packages and Docker images are available for these changes? Given the breaking changes and the database migration required by #186, v0.4.0 would probably be the right number.

No urgency on our side, and thanks a lot for your work on openwec.
