# Changelog

* 0.5.2.0
  - Added itemTag and facetTag that also tag/untags the field.

* 0.5.1.0
  - Added faceted, injected, itemized, projected, which is analogous to Profunctor Choice and Strong
    but using 'Which' and 'Many'
  - Added +||+ (analogous to +++ and |||), >||>; and *&&* (analogous to *** and &&&), and >&&>.

* 0.5.0.0
  - min bounds: data-diverse >=1.2.1
  - Rerranged type variable for xxxL and xxxN functions so that the
    @x@ inferrred from label @l@ or index @n@ is after @proxy@.
    - This affects `item[L|N]`, `item[L|N]'`, `replace[L|N]'`, `facet[L|N]`
    - Same change was made in data-diverse-1.2.0.0

* 0.4.0.1
  - included data-diverse 1.0 in the upper bounds

* 0.4.0.0
  - Changed type variable ordering of 'itemL' and 'itemL', so it's consistently 'x', 'y', then 'xs'

* 0.3.0.0
  - Changed type variable ordering of 'facetL' and 'facetN', so it's consistently 'x' then 'xs'

* pre 0.3.0.0
  - Initial version represented as (Int, Data.Map Int Any)
