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 Sanity?

Sanity's MCP server now explains failed validations and stops skipping them.

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

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.

Sanity's MCP server now explains failed validations and stops skipping them.

◆ Current state

Sanity made Context Knowledge Bases generally available on November 10, letting agents read datasets, websites and files over MCP. The days since have been follow-up: MCP server 2.46.1 and 2.46.2 return stable error codes, explain incomplete validations and stop writes from skipping schema checks, while the console now shows when each robot token was last used. Media Library made PDF previews zoomable and folder counts in big libraries about seven times faster.

◆ Where it's heading

Sanity is making the agent-facing parts dependable: the MCP server is getting the error codes and validation rules a production client needs. Access visibility for tokens and members follows the same push to let teams audit what automated clients do.

◆ Prediction

Expect more MCP server point releases around validation and Knowledge Base commands, and more usage data on tokens and agents in the console.
