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 CodeRabbit?

CodeRabbit moves review rules into a .coderabbit/ folder that sits next to the code.

CodeRabbit is moving from commenting on pull requests to deciding on them. Risk instructions let a team say what is routine and what is risky, so CodeRabbit approves the routine ones and a Triage rule can merge them on GitHub Team plans. This week it locked configuration to a protected branch, added a .coderabbit/ directory where review instructions and pre-merge checks live as Markdown per package, and retired Generate docstrings and the Docstring Coverage check.

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.

C6.3

CodeRabbit moves review rules into a .coderabbit/ folder that sits next to the code.

◆ Current state

CodeRabbit is moving from commenting on pull requests to deciding on them. Risk instructions let a team say what is routine and what is risky, so CodeRabbit approves the routine ones and a Triage rule can merge them on GitHub Team plans. This week it locked configuration to a protected branch, added a .coderabbit/ directory where review instructions and pre-merge checks live as Markdown per package, and retired Generate docstrings and the Docstring Coverage check.

◆ Where it's heading

With approval authority comes tighter control over who writes the rules: protected config branches, then rules stored per package so each service owns its own definition of risky. The product is also trimming side features such as docstring generation to concentrate on review and merge decisions.

◆ Prediction

Expect risk instructions and Automatic Approvals to read from the .coderabbit/ directory per package, and more platforms beyond GitHub Cloud getting the directory and config-source controls.
