11# Revision history for schematic

3+## 0.6.0.0 -- 2021-01-15

5+Added compatability with aeson-1.4.3.0. Since version 1.4.3 the module `Data.Aeson` started exporting `JSONPath`, which was conflicting with our own `JSONPath`. Furthermore, started using `JSONPathElement` from `aeson` instead of `DemotedPathSegment`.

7+## 0.5.1.0 -- 2021-01-15

9+Fix the generation of json schema for numbers.

10+Add array constraints.

11+Fix the generation of text and number constraints.

12+Remove jsonpath from the error message.
