Vercel Sandbox reaches all 20 compute regions

Vercel Sandbox expanded from 4 compute regions to all 20, with routing 18 times faster than before, per Vercel's changelog. Deployment steps run about 10% faster overall, up to 12 seconds saved per deploy on large apps. For anyone running builds through Sandbox, that's less distance between a build and the machine running it, and 12 seconds adds up over a day of iterating on deploys.

The smaller change is the more interesting one. The update adds persistent memory for eve agents through named slots defined under agent/memory/. An agent can hold state across sessions instead of starting cold every time. Vercel also shipped a vercel changelog CLI command built specifically so coding agents can pull it and see what's new.

Right now, agents mostly learn about new capabilities because a human reads a blog post and updates a prompt or a config file. A CLI command that hands the changelog straight to an agent skips that step. If the pattern spreads, writing a changelog stops being just a docs task. It starts looking like an API contract, something a program parses and acts on instead of something a person glances at once and forgets.

Vercel doesn't say how many teams are actually calling the new CLI command yet, or whether other platforms plan anything similar. Whether this stays a Vercel-specific detail or becomes a pattern other platforms copy is the open question.
