Feb 1, 2025February 2025 — tarantool/tarantool: Delivered a critical bug fix focused on changelog accuracy and data integrity warnings for vinyl index double field types. Clarified that suboptimal MessagePack encoding and the presence of double field types can lead to issues, and emphasized that vinyl indexes containing double fields may require a rebuild to prevent data corruption. This improvement enhances reliability, operator guidance, and supports safer upgrades. Commit ceadd1e81804f38e897ba7285482dbaae9d1a6b7 underpins the fix.

Jan 1, 2025In 2025-01, contributed critical stability and correctness improvements to tarantool/tarantool, focusing on replication shutdown reliability, hash index correctness, and numeric precision. Delivered three focused bug fixes with clear business value: improved shutdown safety for the WAL path, removal of template-based hashing to ensure consistent MP_UINT hashing, and aliasing 'double' to 'number' for robust numeric comparisons. These changes reduce downtime, prevent data inconsistencies, and simplify future maintenance.
