+MixedModels v4.25.4 Release Notes
+==============================
+- Added additional precompilation for rePCA. [#749]
+
 MixedModels v4.25.3 Release Notes
 ==============================
 - Fix a bug in the handling of rank deficiency in the `simulate[!]` code. This has important correctness implications for bootstrapping models with rank-deficient fixed effects (as can happen in the case of partial crossing of the fixed effects / missing cells). [#778]
