0.9.0 - 2026-06-04
After 2 months, v0.9.0 is finally here.
This release's major focus is on bringing the hybrid architecture, which lets users move gradually from the push model to the agent based pull model within the same Argo CD instance, and eliminates the need to have an agent for the control plane to manage it using GitOps. Most of the work related to the hybrid architecture has been done by @chetan-rns, thanks a lot!
Furthermore, there is now a Helm chart for installing the principal (thanks @enbiyagoral), changes to logging, some minor performance related changes, bug fixes and a ton more.
Thanks to all the people who contributed to this release!
