11# Revision history for schematic

3−## 0.6.0.0 -- 2021-01-15

4−

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`.

6−

7−## 0.5.1.0 -- 2021-01-15

8−

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.

13−

143## 0.5.0.0 -- 2019-02-20

154

165GHC 8.6, json generation by schema definition, validation bug fixes, better
