What is Argo CD?

Argo CD's 3.6 candidates have narrowed to cherry-picked fixes

Argo CD is in the late candidate phase for 3.6: rc3 and rc4 carry cherry-picked fixes for repo-server goroutine leaks, SOCKS5 SSH fetching, sharding distribution and server-side diff, plus one new option to configure Dex TLS cipher suites. The gitops-engine version bumps track the same candidates.

What is Sonic?

Sonic yanks two releases in a day, then ships faster ingest and new count commands.

Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.

Argo CD vs Sonic: editorial side-by-side

5.0

Argo CD's 3.6 candidates have narrowed to cherry-picked fixes

◆ Current state

Argo CD is in the late candidate phase for 3.6: rc3 and rc4 carry cherry-picked fixes for repo-server goroutine leaks, SOCKS5 SSH fetching, sharding distribution and server-side diff, plus one new option to configure Dex TLS cipher suites. The gitops-engine version bumps track the same candidates.

◆ Where it's heading

The release train moves through numbered candidates that shrink to fixes before a stable cut, the same shape 3.4 and 3.5 followed. Feature work concentrates on the source hydrator, ApplicationSet scale and authentication plumbing, while candidates handle hardening.

◆ Prediction

3.6.0 stable is the next likely entry, given rc4 is fixes-only.

2.5

Sonic yanks two releases in a day, then ships faster ingest and new count commands.

◆ Current state

Sonic is a lightweight Rust search index that gained BM25 ranking in 1.8. On September 21 it released 1.9.0 with large PUSH performance gains and 1.9.1, then yanked both over two serious bugs and shipped 1.10.0 the same day with new COUNTC, COUNTB and COUNTO commands replacing COUNT. 1.10.1 fixed a CJK tokenizer panic on Chinese text and object counting, and 1.10.2 repaired backups.

◆ Where it's heading

The 1.x line is moving fast on ingest performance and correctness for high-scale and non-English users, at the cost of some unstable releases. Experimental APIs are being tested in production before they reach official builds.

◆ Prediction

Expect the experimental high-scale PUSH features to graduate out of the feature flag in a later 1.x; when is unclear.
