 * Move `Data.Aeson.Parser` module into separate [`attoparsec-aeson`](https://hackage.haskell.org/package/attoparsec-aeson) package, as these parsers are not used by `aeson` itself anymore.
 * Use [`text-iso8601`](https://hackage.haskell.org/package/text-iso8601) package for parsing `time` types. These are slightly faster than previously used (copy of) `attoparsec-iso8601`.
   Formats accepted is slightly changed:
-  - The space between time and timezone offset (in `UTCTime` and `ZonedTime`) is disallowed. ISO8601 explicitly forbidds it.
+  - The space between time and timezone offset (in `UTCTime` and `ZonedTime`) is disallowed. ISO8601 explicitly forbids it.
   - The timezone offsets can be in range -23:59..23:59. This is how Python, joda-time etc seems to do. (Previously the range was -12..+14)
 
 * Remove internal `Data.Aeson.Internal` and `Data.Aeson.Internal.Time` modules. Everything from the former is exported elsewhere (`Data.Aeson.Types`), the latter was truly internal.
