A tracker collecting releases, breaking changes, model retirements, and pricing changes across 20+ coding agents.

Landing page captured for the 2026-10-18 issue.

For: Developers tracking changes across coding agents
Worth noticing: Cline release notes identify a parameter mismatch that had caused requests to OpenAI and Azure-compatible endpoints to be rejected.

Field notes

Entries distinguish releases from model, pricing, and retirement changes, and link out to named sources such as changelogs and deprecation pages. The visible feed ranges across multiple tools and versions; a Claude Code v2.1.302 entry, for example, lists 63 changes, while other entries capture smaller compatibility fixes.
