Last week I wrote about the eight regressions in Claude Code 2.1.119/120. This week, Anthropic responds with three releases in 48 hours. Let’s see what’s inside.
v2.1.121 — MCP gets ‘alwaysLoad’
The biggest feature in 2.1.121 is the new alwaysLoad option for MCP server configurations. Set alwaysLoad: true on a server, and all its tools load immediately — no more waiting for tool-search deferral. If you rely heavily on specific MCP servers, this is a real quality-of-life win.
Also new: claude plugin prune cleans up orphaned plugin dependencies. Anyone who’s experimented with plugins knows the problem — after a few install/uninstall cycles, leftovers accumulate. Now there’s a clean way to tidy up.
v2.1.122 — PR URLs in Resume and telemetry fixes
There’s a clever feature in 2.1.122: paste a PR URL into the /resume search box, and Claude Code automatically finds the session that created that PR. Works with GitHub, GitHub Enterprise, GitLab, and Bitbucket. Sounds small, but it’s incredibly practical in daily use — no more digging through old sessions to find the context behind a PR.
On the technical side, OpenTelemetry events got improved — numeric attributes are now emitted as actual numbers instead of strings. And there’s a new claude_code.at_mention log event that fires when an @-mention gets resolved.
Important bugfix: /branch could fail to correctly fork sessions that contained entries from rewound timelines. This produced cryptic error messages about missing tool_result blocks. Fixed.
v2.1.123 — OAuth emergency fix
The smallest of the three releases, but critical for those affected: when CLAUDE_CODE_DISABLE_EXPERIMENTAL_BETAS=1 was set, OAuth authentication got stuck in an infinite 401 retry loop. For enterprise users who deliberately disable experimental features, this was a blocker.
My take
After the bumpy weekend with 2.1.119/120, the team is showing it can move fast. The three releases are solid — not flashy, but exactly what’s needed right now: stability, small improvements, and quick bugfixes. The alwaysLoad option for MCP servers alone is worth the update.
