+## [0.11.19] - 2025-10-22
+
+Version 0.11.19 is equivalent to 0.12.1. It is being released to help mitigate impact from 0.11.18 being inadvertently released ahead of schedule. This version contained a breaking change and defects related to internal refactors. While 0.11.19 still contains a breaking change from 0.11.17 it does fix defects (see details below) for any users relying on the latest 0.11.x version.
