What is Fiber?

Fiber marks its v2 module deprecated in favour of v3

Fiber's v2 line has been on narrow maintenance for months: lock cleanup, an X-Real-IP backport, HTML escaping, a CVE patch. v2.52.16 formally marks the fiber/v2 module as deprecated in favour of v3 and fixes CORS wildcard origins that accepted empty subdomain labels. The v3 line, last visible in this feed at rc.3, carries native net/http and fasthttp handler support and Express-style handlers.

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.

Fiber marks its v2 module deprecated in favour of v3

◆ Current state

Fiber's v2 line has been on narrow maintenance for months: lock cleanup, an X-Real-IP backport, HTML escaping, a CVE patch. v2.52.16 formally marks the fiber/v2 module as deprecated in favour of v3 and fixes CORS wildcard origins that accepted empty subdomain labels. The v3 line, last visible in this feed at rc.3, carries native net/http and fasthttp handler support and Express-style handlers.

◆ Where it's heading

The deprecation notice tells v2 users to plan their move. With v2 patches shrinking to one or two pull requests, active development sits entirely on v3.

◆ Prediction

Further v2 releases are likely to be security fixes only; the feed does not show v3's current state past rc.3.

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.
