2.9.3

Feature:

  • Add optional feature argument to feature_flag_on? and which_variant methods of ActorControl, to reuse an existing feature.
  • Add mutex to synchronise access to caches in Cache::FetchWrapper.

2.9.2

Bug fix:

  • Fix parsing fixed determinations when the variant is an empty string

2.9.1

Feature:

  • Add callback argument to Control, allowing custom logic to notice the determination.

2.9.0

Feature:

  • When an app_version does not comply with semantic versioning specifications (e.g.: 2021.11.05 with a trailing zero instead of the correct 2021.11.5), return false.

2.8.0

Feature:

  • When a GUID bucketed feature is misconfigured, handle the error and return false.

2.7.1

Feature:

  • Add before_retrieve and after_retrieve hooks for Determinator::Retrieve::HttpRetriever

2.7.0

⚠️ This release includes breaking changes ⚠️

Interface change:

  • Constraints which are not arrays of strings are no longer accepted; if present, the library returns false and logs an error.

2.6.0

Interface change:

  • A feature_cache is now required to use Determinator. See the examples/determinator-rails/config/initializers/determinator.rb for a quick start.

2.5.4

Bug fix:

  • Apply app_version logic to structured request.app_version too

2.5.3

Bug fix:

  • Avoid errors when updating the gem and using persistent cache resulting in null fixed_determinations

2.5.2

Feature:

  • Add structured_bucket to Feature
  • Add #retrieve method to the Control
  • Add optional feature argument to feature_flag_on? and which_variant, to reuse an existing feature

2.5.1

Feature:

  • Add explain functionality for determinations

2.5.0

Feature:

  • Add fixed determinations

2.4.4

Bug fix:

  • Count repeated determinations instead of tracking separately

2.4.3

Feature:

  • Add Sinatra endpoint tracking

Bug fix:

  • Remove endpoint tracking of PATH_INFO

2.4.2

Feature:

  • Add endpoint information to tracking request

Bug fix:

  • Make tracking request "start" attribute an actual time

2.4.1

Bug fix:

  • Update "fake" retrievers to match behaviour introduced in v2.3.1 when a feature is missing

2.4.0

Feature:

  • Add tracker middleware

v2.3.1 (2019-05-25)

Feature:

  • Add a flag cache_missing[true] to the cache wrapper to control the cache behaviour on 404

Bug fix:

  • Ensure errors are not cached by the cache wrapper

v2.3.0 (2019-09-06)

Feature:

v2.2.1 (2019-07-29)

Bug fix:

  • Ensures the dependency to semantic is included at runtime

v2.2.0 (2019-07-25)

Feature:

  • Adds support for app_version constraints (#60)

v2.1.0 (2019-05-01)

Feature:

  • Adds HttpRetriever and cascading cache support (#58)

v2.0.0 (2019-02-19)

Breaking change:

  • Removes routemaster-drain support, the gem is also no longer a dependency. (#55)

Feature:

  • Adds retriever for Dynaconf. (#55)

v1.2.0 (2018-06-12)

Feature:

  • Adds to how single bucketed features operate. Now rollouts imply random determination, though 0% rollouts and 100% rollouts remain representing no-one and everyone respectively, ensuring that this change is backward compatible. (#52)

v1.1.2 (2018-03-07)

Bug fix:

  • Ensures that Determiantor::Retrievve::File tolerates feature names that quack #to_s. (#50)

v1.1.1 (2018-02-27)

Bug fix:

  • Ensures the configure method calls the correct method when a legacy error proc is given as a parameter. (#49)

v1.1.0 (2018-02-07)

⚠️ This release includes breaking changes to RSpec::Determinator ⚠️

Breaking change:

  • If two forced_determinations are made within one rspec test case, it is now the last one that takes precedence (not the first). (#47)

Bug fix:

  • forced_determinations which are called with differently typed parameters (eg. integer vs. string, boolean vs. string) will now work in the same way that real determination will. (#47)

v1.0.0 (2018-02-05)

⚠️ This release includes breaking changes ⚠️

Breaking change:

  • Changes retrieval caching so that 404s are cached as well as positive feature retrievals. This means that an unconfigured feature won't result in a thundering herd of requests to Florence. (#46)

Feature:

  • Changes tests to use the Determinator standard tests (#41)
  • Supports the use of the 'single' bucket type for features, which allows (only) feature flags to be on or off, without any id or guid specified. (#41)
  • Adds Determintion callbacks: trigger a block when a determination is made, allowing for experiment tracking. (#45)

v0.12.1 (2018-02-01)

Bug Fix:

  • Allow .for_actor calls when using RSpec::Determinator to test code that uses determinator. (#44)

v0.12.0 (2018-01-23)

Feature:

  • Adds the Determinator.feature_details method, which allows lookup of feature details as are currently available to Determinator. Whatever is returned here is what Determinator is acting upon. (#38)

Bug Fix:

  • Upgrades a dependency of the example rails app which has a known vulnerability. (#39)

v0.11.1 (2017-10-27)

Feature:

  • Allows the use of example-scoped variables for outcomes and constraints in RSpec::Determinator's mocks. (#36)

v0.11.0 (2017-10-13)

Bug fix:

  • Ensure constraints and properties are string-keyed so that they match regardless of which are used (#33)
  • Be more permissive with the situations where Rspec::Determinator can be used (#34)
  • Swallow not found errors from routemaster so determinator isn't too shouty, allow them to be tracked. (#35)

v0.10.0 (2017-09-15)

Feature:

  • Determinator can now be configured to log errors with any external service (#32)

v0.9.1 (2017-09-14)

Bug fix:

  • Fixes an issue where PR #27 missed one instance of syntactic sugar where constraints needed to be switched to properties. (#30)

v0.9.0 (2017-09-14)

This version of Determiantor introduces some breaking changes as we move to getting the Florence ecosystem more ready for a wider audience. A 1.0.0 release will follow shortly with few additional features, but with significantly more documentation.

Breaking changes:

  • When asking for a determination, you must specify the properties of the given actor, not the constraints (as constraints makes less sense) (#27)
  • Remove siphon drain step, determinator now requires just a drain that expires caches. Also Removes the caching step for ID lookup (#24)

Features:

  • Added Determinator RSpec helper (#26)
  • Allows Determinator to accept both legacy and new style contraint and override specifications, for upcoming Florence API migration (#25)
