Unreleased

5.0.1 - 2024-03-27

Changed

  • make user-agent headers more descriptive (#168)

Fixed

  • make client more resilient to non-conforming responses from unleash-edge (#162)
    • while the unleash server provides always valid responses, (at least some versions of) unleash-edge can provide an unexpected JSON response (null instead of empty array).
    • fixed the handling of the response, so we do not throw exceptions in this situation.

5.0.0 - 2023-10-30

Added

  • change seed for variantutils to ensure fair distribution (#160)
    • client specification is here
    • A new seed is introduced to ensure a fair distribution for variants, addressing the issue of skewed variant distribution due to using the same hash string for both gradual rollout and variant allocation.

4.6.0 - 2023-10-16

Added

  • dependant toggles (#155)
    • client specification is here

4.5.0 - 2023-07-05

Added

  • variants in strategies (#148)

Fixed

  • groupId override for variants

4.4.4 - 2023-07-05

Fixed

  • flexible rollout strategy without context (#146)

4.4.3 - 2023-06-14

Added

  • Add Context#to_h method (#136)

Fixed

  • Bootstrapped variants now work when client is disabled (#138)
  • Variant metrics are now sent correctly to Unleash. Fixed a typo in the payload name. (#145)

Changed

4.4.2 - 2023-01-05

Added

  • allow passing user_id as integer (#119)

4.4.0 - 2022-09-19

Added

4.3.0 - 2023-07-14

Added

Fixed

Changed

  • Refactored ToggleFetcher#read! (#106)

4.2.1 - 2022-03-29

Fixed

  • correct logic for default values on feature toggles so toggle value respected when toggle exists and default is true (#93)

4.0.0 - 2021-12-16

Added

  • Support for projects query (requires unleash 4.x) (#38)
  • Allow passing blocks to is_enabled? to determine default_result (#33)
  • Implement custom stickiness (#69)
  • Allow using custom_http_headers from the CLI utility (#75)

Fixed

  • Allow context to correctly resolve camelCase property values (#74)
  • Avoid unlikely situation of config changing under the read operation due to backup path file being incorrectly set (#63)

Changed
