Optimized Confluence RPC by adding confluence_space_id field to eliminate redundant queries for large page lists that previously caused URL length limit issues (merged Mar 19, PR #9583)
Improved frontend polling efficiency for publish workflows by changing from unconditional 8-second intervals to conditional 15-second intervals only during INDEXING state (merged Mar 19, PR #9576)
Filtered out PRs/MRs via database query during thread diffing to improve indexing performance (merged Mar 17, PR #9506)
Optimized GitHub repository syncing to reduce issue/PR count syncing to once per day with DataDog bot blacklisting (merged Mar 18, PR #9562)
Made MCP request logging asynchronous to reduce request handling latency (merged Mar 20, PR #9590)

Infrastructure & Internal Tooling#

Added comprehensive lint-fe and lint-be skill packages with deterministic shell scripts for consistent frontend and backend linting workflows (merged Mar 21, PR #9620)
