v0.20.2
One fix for a production outage first seen in 0.20.0 where the agent exhausted EFS burst credits by sweeping all project directories on every transcript lookup.
- The agent swept every project directory on EFS on every transcript lookup, exhausting
EFS burst credits and slowing all sessions to a crawl.
filepath.Glob("projects/*/<sid>.jsonl")expands the wildcard by calling ReadDir on the projects directory and then on each matched subdirectory. With 38 project directories in production, a single workspace agent issued 821 directory reads per second, consuming the entire EFS burst budget across all workspaces. The fix memoises theprojects/*scan so that the per-project ReadDir only runs when the cached project path is stale, cutting EFS metadata I/O by roughly 99 %.
Upgrade notes
Section titled “Upgrade notes”No action needed on the ECS deployment — the Control Plane image update is enough for the Console changes from 0.20.1.
All workspace users must restart their workspaces to receive the agent fix from both 0.20.1 and 0.20.2. Workspaces that were running during or before the upgrade are still on the previous agent binary; the Console will show a “restart required” badge until they do.
