+- [SRCH-1387] workspace refresh caching using incorrect key `(PR #4859)`
+  - Fixes issue [https://linear.app/sourcegraph/issue/SRCH-1387/chime-workspaces-not-updating](https://linear.app/sourcegraph/issue/SRCH-1387/chime-workspaces-not-updating)The workspace preview components rely on the apollo client cache to coordinate the state. Queries are made in two places;
+- /client/web/src/enterprise/batches/batch-spec/edit/workspaces-preview/useWorkspacesPreview.ts
+- /client/web/src/enterprise/batches/batch-spec/edit/workspaces-preview/useWorkspaces.tsThe desired effect is that both queries are cached under the same cache-key by apollo, and so when a query finds new results it triggers a component refresh with the new data.The problem is that there is a subtle difference in the variables passed to the query - One has `after: null` and on does not provide the `after` field. This means that they are treated as different queries and the cache entries for the queries are separate.
+- Update auto-updating script to use correct scip-typescript Docker tag `(PR #4722)`
