Changelog for LeanCheck

v1.0.0 (August 2022)

This release indicates that the Test.LeanCheck API is now stable. This is the same as v0.9.12 with just the version number change, the major bump here serves just to indicate stability. If your project works with the 0.9 series, it will work with the 1.0 series.

v0.9.12 (August 2022)

• replace enumeration of Fractional and Floating types by the Calkin-Wilf sequence:
  • add listFloating and listFractional;
  • deprecate tiersFloating and tiersFractional;
• improve the changelog with timestamps and history down to v0.5.0;
• normalize code formatting throughout: indentation, spacing and width;
• improve testing of LeanCheck itself;
• test on GHC 9.2 and 9.4 (works with no changes).

v0.9.10 (June 2021)

• Test.LeanCheck.Utils.Type: derive Typeable instances on GHC 7.8. Behaviour on newer GHCs (>= 7.10) versions is unaffected as they automatically derive Typeable instances for all types.

v0.9.8 (June 2021)

• Test.LeanCheck.Utils.Type: ~Typeable instances on GHC 7.10.~ ~Behaviour on newer GHCs (>= 8.0) versions is unaffected~ ~as they automatically derive Typeable instances for all types.~ Update: these instances were already present on v0.9.6. LeanCheck v0.9.8 is essentially the same as v0.9.6.

v0.9.6 (May 2021)

• no code changes in what is exported by Test.LeanCheck
• Test.LeanCheck.Utils.Types: export the A, B, C, D, E and F types
• slightly improve README
• improve Makefile and tests
