Changelog of @hackage/monoidal-containers 0.6.1.0

Monoidal containers

Drop official support for GHC 7.8.4
Require containers 0.5.9 or greater.
Support lens-5, semialign-1.2, and aeson-2
MonoidalMap and MonoidalMap.Strict: Add several functions added to Data.Map since 0.5 up to 0.5.9: take, drop, splitAt, lookupMin, lookupMax, restrictKeys, withoutKeys, fromDescList, fromDescListWith, fromDescListWithKey, fromDistinctDescList, takeWhileAntitone, dropWhileAntitone, spanAntitone, and traverseMaybeWithKey
Add instances of Filterable and Witherable from the witherable package
Add Control.Lens.Wrapped.Rewrapped instances.

Deprecates 0.5.* and reverts behavior of fromList, insert, mapKeys, etc. to match behavior in Data.Map. The only difference in behavior between Data.Map.Monoidal.MonoidalMap and Data.Map.Map is now the semigroup and monoid instances (as was the case in 0.4 and earlier).
Fix the argument order of Data.HashMap.Monoidal.insert
Remove Data.HashMap.Monoidal.insertOrReplace as it is now identical to Data.HashMap.Monoidal.insert
Added Data.HashMap.Monoidal.insertWith and Data.HashMap.Monoidal.fromListWith

Add a flag, split-these, to select whether to use the new "these"/"semialign" packages or the older combined "these" package.
Add default.nix to make it easier to hack on this package in nix

Added Data.IntMap.Monoidal and Data.IntMap.Monoidal.Strict, corresponding to Data.IntMap and Data.IntMap.Strict
Make fromList, insert, and mapKeys from Data.Map.Monoidal and Data.Map.Monoidal.Strict require Semigroup on values to properly capture monoidal behavior instead of reverting to the left-biased semantics of Data.Map.
Add Align instances and, for sufficiently recent versions of these, Semialign instances
Support these 0.8.0

General changes:

Weakened Monoid constraints to Semigroup whenever possible as enabled by the Semigroup-Monoid proposal. This includes,
