CHANGELOG

# Changelog for Hedis

## 0.16

- PR #176. Exposed RedisArg type class so it's possible to (de)serialize application data structures.
- PR #182. Add MonadTrans instance for MonadRedis.
- PR #198. Extended Redis 6 and 7 support.
  - add xgroupCreate, xgroupCreateConsumer, xgroupSetId;
  - added support of the message trimming by message;
  - add support for count parameter for approximate trimming.
  
Breaking changes:

- **xpendingDetail** instead of 'Maybe ByteString' for a consumer name the method
receives XPendingOpts structure that can take number of milliseconds and consumer name.
In order to preserve an old behavior code should be rewritten as:
  xpendingDetails s g f l t Nothing -> xpendingSummary s g f l t defaultXPendingDetailOpts
  xpendingDetails s g f l t (Just c) -> xpendingSummary s g f l t defaultXPendingDetailOpts{xPeedingDetailConsumer=Just c)
- **xpendingSummary** no longer accepts consumer arguments as it was done in violation to spec and methodd never worked this way
- **XTrimOpts** type changed, because previous type didn't hold library invariants now instead of a simple ADT XTrimOpts is data that defines strategy of trimming and type, exact or approximate. Here is a conversion table:
  NoArg -> is not representable,
   In xaddOpts options use Nothing instead;
   In xtrim using NoArgs as a bug.
  Maxlen n -> TrimOpts{trimOptsStrategy=TrimMaxlen n, trimOptsType=TrimExact};
  MaxlenApprox n -> TrimOpts{trumOptsStrategy=TrimMaxlen n, trimOptsType=TrimApprox Nothing};

  properly handle Redis returning `nil`-replies: `brpoplpush`, `lindex`, `lpop`,

  `zrank`, `zrevrank`, `zscore`.
