Argo CD release candidate: internal mTLS and source-integrity configuration

The news at the time

The official Argo CD v3.5.0-rc1 page labels this artifact a pre-release and lists mTLS support in the repo-server. That supports describing a release-candidate capability, not claiming that every installation has mTLS enforced.

The same changelog lists CLI support for Source Integrity configuration and an exposed ApplicationSet UI. This brief does not assert that signature verification first appeared in this release or that earlier internal traffic was always unencrypted.

Follow-up checked during renewal

No additional follow-up fact was established in this renewal. This does not establish that nothing changed.

What to review before applying this

The linked official blog could not be collected; this narrower draft uses the project’s release artifact. Review upgrade notes, certificates, trust roots and the target version’s integrity settings before rollout. It is not a claim that the candidate remains the newest version.

Editorial review suggestions; no hands-on product experiment was performed.
