The change adds dictType…
Vitah Lin addressed infrastructure maintenance by upgrading GitHub Actions to their latest stable versions, moving away from deprecated Node.js 20 actions ahead of the June 2026 forced migration to Node.js 24. The update touches ten workflow files across the CI pipeline.
Two targeted fixes were also merged. Shubham Taple corrected an off-by-one error in listpack backlen encoding that was causing boundary values to use wider encoding than necessary, wasting bytes. YangboLong fixed memory accounting in multiStateMemOverhead to properly calculate overhead for both pointer arrays and…
