2026 Changelog

Backported in #98402: The loop table function was calling inner_storage->read() directly, bypassing the interpreter layer where row policies, column-level grants, and other security checks are applied. This allowed a user restricted by row policies to read all rows via loop(table) even when a direct SELECT returned zero rows. #97682 (pufit).
Backported in #98310: Fix incorrect result of FINAL queries when mixing primary key and non primary key skip indexes. #98097 (Raúl Marín).

Backported in #98326: Fix out-of-bounds access in ColumnConst::getExtremes that could cause a crash when extremes = 1 is enabled. #98263 (Alexey Milovidov).
Backported in #98388: Fixed LOGICAL_ERROR exception "Invalid binary search result in MergeTreeSetIndex" triggered by toDate conversion on key columns with data crossing the 65535 boundary. #98276 (Alexey Milovidov).
