Changes
0.9
- Removed
FieldName
, the relic of the old ages(@=)
,@==
,@!?
andlasso
now takeProxy
instead ofFieldName
. Those who are usingmkField
need to replace the operands with proxies (OverloadedLabels is recommended).
- Supported aeson 1.x
- Introduced
IsLabel
flag which toggles the presence of opticsOverloadedLabels
. By disabling it, this package can now coexist with other users of theIsLabel
class, such asgeneric-lens
andrelational-query
.
0.8.3
Comp
is now a pattern synonym forCompose
- Added missing
liftTyped
implementations - Supported aeson-2.0
