# Changelog All notable changes to this project will be documented in this file, in reverse chronological order by release. ## 2.7.7 - 2016-04-12 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#59](https://github.com/zendframework/zend-stdlib/pull/59) fixes a notice when defining the Zend\Json\Json::GLOB_BRACE constant on systems using non-gcc glob implementations. ## 2.7.6 - 2016-02-19 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#56](https://github.com/zendframework/zend-stdlib/pull/56) updates the `AggregateHydrator` implementation to add overrides for the `hydrate()` and `extract()` methods; this was done to ensure they trigger zend-stdlib-specific event classes (vs the zend-hydrator base classes), in order to ensure backwards compatibility. ## 2.7.5 - 2016-02-16 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#54](https://github.com/zendframework/zend-stdlib/pull/54) updates the `HelperPluginManager` implementation to return zend-stdlib-specific instances (instead of zend-hydrator instances), to ensure backwards compatibility when typehinting against the zend-stdlib types. ## 2.7.4 - 2015-10-15 ### Added - Nothing. ### Deprecated - [#35](https://github.com/zendframework/zend-stdlib/pull/35) deprecates `Zend\Stdlib\CallbackHandler`, as the one component that used it, zend-eventmanager, will no longer depend on it starting in v3. ### Removed - Nothing. ### Fixed - Nothing. ## 2.7.3 - 2015-09-24 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#27](https://github.com/zendframework/zend-stdlib/pull/27) fixes a race condition in the `FastPriorityQueue::remove()` logic that occurs when removing items iteratively from the same priority of a queue. ## 2.7.2 - 2015-09-23 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#26](https://github.com/zendframework/zend-stdlib/pull/26) fixes a subtle inheritance issue with deprecation in the hydrators, and updates the `HydratorInterface` to also extend the zend-hydrator `HydratorInterface` to ensure LSP is preserved. ## 2.7.1 - 2015-09-22 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#24](https://github.com/zendframework/zend-stdlib/pull/24) fixes an import in `FastPriorityQueue` to alias `SplPriorityQueue` in order to disambiguate with the local override present in the component. ## 2.7.0 - 2015-09-22 ### Added - [#19](https://github.com/zendframework/zend-stdlib/pull/19) adds a new `FastPriorityQueue` implementation. It follows the same signature as `SplPriorityQueue`, but uses a performance-optimized algorithm: - inserts are 2x faster than `SplPriorityQueue` and 3x faster than the `Zend\Stdlib\PriorityQueue` implementation. - extracts are 4x faster than `SplPriorityQueue` and 4-5x faster than the `Zend\Stdlib\PriorityQueue` implementation. The intention is to use this as a drop-in replacement in the `zend-eventmanager` component to provide performance benefits. ### Deprecated - [#20](https://github.com/zendframework/zend-stdlib/pull/20) deprecates *all hydrator* classes, in favor of the new [zend-hydrator](https://github.com/zendframework/zend-hydrator) component. All classes were updated to extend their zend-hydrator equivalents, and marked as `@deprecated`, indicating the equivalent class from the other repository. Users *should* immediately start changing their code to use the zend-hydrator equivalents; in most cases, this can be as easy as removing the `Stdlib` namespace from import statements or hydrator configuration. Hydrators will be removed entirely from zend-stdlib in v3.0, and all future updates to hydrators will occur in the zend-hydrator library. Changes with backwards compatibility implications: - Users implementing `Zend\Stdlib\Hydrator\HydratorAwareInterface` will need to update their `setHydrator()` implementation to typehint on `Zend\Hydrator\HydratorInterface`. This can be done by changing the import statement for that interface as follows: ```php // Replace this: use Zend\Stdlib\Hydrator\HydratorInterface; // with this: use Zend\Hydrator\HydratorInterface; ``` If you are not using imports, change the typehint within the signature itself: ```php // Replace this: public function setHydrator(\Zend\Stdlib\Hydrator\HydratorInterface $hydrator) // with this: public function setHydrator(\Zend\Hydrator\HydratorInterface $hydrator) ``` If you are using `Zend\Stdlib\Hydrator\HydratorAwareTrait`, no changes are necessary, unless you override that method. - If you were catching hydrator-generated exceptions, these were previously in the `Zend\Stdlib\Exception` namespace. You will need to update your code to catch exceptions in the `Zend\Hydrator\Exception` namespace. - Users who *do* migrate to zend-hydrator may end up in a situation where their code will not work with existing libraries that are still type-hinting on the zend-stdlib interfaces. We will be attempting to address that ASAP, but the deprecation within zend-stdlib is necessary as a first step. In the meantime, you can write hydrators targeting zend-stdlib still in order to guarantee compatibility. ### Removed - Nothing. ### Fixed - Nothing. ## 2.6.0 - 2015-07-21 ### Added - [#13](https://github.com/zendframework/zend-stdlib/pull/13) adds `Zend\Stdlib\Hydrator\Iterator`, which provides mechanisms for hydrating objects when iterating a traversable. This allows creating generic collection resultsets; the original idea was pulled from [PhlyMongo](https://github.com/phly/PhlyMongo), where it was used to hydrate collections retrieved from MongoDB. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - Nothing. ## 2.5.2 - 2015-07-21 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#9](https://github.com/zendframework/zend-stdlib/pull/9) fixes an issue with count incrementation during insert in PriorityList, ensuring that incrementation only occurs when the item inserted was not previously present in the list. ## 2.4.4 - 2015-07-21 ### Added - Nothing. ### Deprecated - Nothing. ### Removed - Nothing. ### Fixed - [#9](https://github.com/zendframework/zend-stdlib/pull/9) fixes an issue with count incrementation during insert in PriorityList, ensuring that incrementation only occurs when the item inserted was not previously present in the list.
