 # Changelog for the optimized Picnic implementation
 
+## Version 3.0.12 -- 2022-03-29

+* Improve matrix multiplication for L5 instances on AVX2. This improves the performance of Picnic-L5-{FS,UR} by up to 5 %.
+* Reduce memory usage and initialization cost for trees.
+* Make the use of `mzd_local_t` as SIMD registers explicit. This change avoids potential issues when not following the rules for accessing members of unions.
+* Clear temporary copies of private keys.
