@@ -1,21 +1,34 @@+# 0.4.1.0++- **Bug fix**: `Data.RAList.Co` — off-by-one in all index operations (`!!`, `lookup`, `lookupM`, `lookupWithDefault`, `lookupCC`). Index formula was `length - n` instead of `length - 1 - n`.+- **Bug fix**: `Data.RAList.Co.adjust` — infinite recursion (called itself instead of `QRA.adjust`).+- **Bug fix**: `Data.RAList.Co.genericReplicate` — infinite recursion (called itself instead of `QRA.genericReplicate`).+- Widened dependency bounds for GHC 9.14 (base < 6, deepseq < 1.7, transformers < 0.7, hspec < 2.12).+- Added test coverage for `Data.RAList.Co` (35 new tests).+ # 0.4.0.0 -* flipped the argument order for `Co.lookup` to be consistent between-both flavors of RAList apis+- Breaking change to api to make api flavors more consistent.  # 0.3.0.0-* changed type from-  `lookupM :: forall (m :: * -> *) a. Monad m => Word64 -> Top a -> m a` to `lookupM :: forall a. Word64 -> Top a -> Either String a`-* added `Data.RAList.Flip`, which flips the counting by having the zeroth index be the last element of the skew binary list,-rather than the head element. +- Added `Data.RAList.Co` module for reversed (co-indexed) access lists.+- Added filter/catMaybe/wither family of operations.+- Added NFData/NFData1 instances.+- Added indexed traversal instances (FunctorWithIndex, FoldableWithIndex, TraversableWithIndex).+ # 0.2.1.1-Fix bug in log n time drop +- Documentation tweaks.+ # 0.2.1.0-Added missing traversable instance +- Various improvements.+ # 0.2.0.0-updated version of ralist-includes bug fixes, api cleanup,-test suite and logarithmic drop contributed by Nell White++- Major rework by Carter Schonwald.++# 0.1.0.0++- Initial release by Lennart Augustsson.
