google/heir v2026.10.01
google/heir published release v2026.10.01 on GitHub on 2026-10-01, a changelog of pull requests mostly by AlexanderViand plus several copybara-service[bot] commits, with contributions from j2kun and mdgrs. Changes include deterministic ordering of preprocessing storage element types, native lowering of chained secret Chebyshev evaluations, Taylor approximation of math.exp made opt-in, a batch PCMM diagonal kernel, preserved linear_transform in the Lattigo backend, and destination-style bufferization for cheddar. The listed notes include several fixes (e.g. preventing operand attribute corruption in canonicalizers) but no explicit security fix is stated in the visible text, which is truncated.
