Sep 16, 2026: CoCo Desktop v1.21.5¶

CoCo Desktop v1.21.5 is a small quality release on top of v1.21.4, focused on error messages that tell you what to do next:

Recovery guidance when a local dbt executable is missing: A Run or Build that can’t find dbt now explains how to recover in the Current Project Output panel, instead of showing only a failed marker.
Clearer errors when a shared skill or plugin can’t be installed: A missing or inaccessible catalog object now points you to the current account and role.
More accurate memory guidance for the agent: The agent’s instructions distinguish memory already supplied in context from records that need an explicit cortex memory recall, and set a tighter bar for saving durable memories.
