# ChangeLog All notable changes are documented in this file using the [Keep a CHANGELOG](http://keepachangelog.com/) principles. ## [5.0.3] - 2020-10-26 ### Fixed * `SebastianBergmann\Timer\Exception` now correctly extends `\Throwable` ## [5.0.2] - 2020-09-28 ### Changed * Changed PHP version constraint in `composer.json` from `^7.3 || ^8.0` to `>=7.3` ## [5.0.1] - 2020-06-26 ### Added * This component is now supported on PHP 8 ## [5.0.0] - 2020-06-07 ### Changed * Parameter type for `SebastianBergmann\Timer\Duration::fromMicroseconds()` was changed from `int` to `float` * Parameter type for `SebastianBergmann\Timer\Duration::fromNanoseconds()` was changed from `int` to `float` * Return type for `SebastianBergmann\Timer\Duration::asNanoseconds()` was changed from `int` to `float` ### Fixed * [#31](https://github.com/sebastianbergmann/php-timer/issues/31): Type Error on 32-bit systems (where `hrtime()` returns `float` instead of `int`) ## [4.0.0] - 2020-06-01 ### Added * Introduced `Duration` value object for encapsulating a duration with nanosecond granularity * Introduced `ResourceUsageFormatter` object for formatting resource usage with option to explicitly pass a duration (instead of looking at the unreliable `$_SERVER['REQUEST_TIME_FLOAT']` variable) ### Changed * The methods of `Timer` are no longer static * `Timer::stop()` now returns a `Duration` value object ### Removed * Functionality that is now implemented in `Duration` and `ResourceUsageFormatter` has been removed from `Timer` ## [3.1.4] - 2020-04-20 ### Changed * `Timer::timeSinceStartOfRequest()` no longer tries `$_SERVER['REQUEST_TIME']` when `$_SERVER['REQUEST_TIME_FLOAT']` is not available (`$_SERVER['REQUEST_TIME_FLOAT']` was added in PHP 5.4 and this library requires PHP 7.3) * Improved exception messages when `$_SERVER['REQUEST_TIME_FLOAT']` is not set or is not of type `float` ### Changed ## [3.1.3] - 2020-04-20 ### Changed * `Timer::timeSinceStartOfRequest()` now raises an exception if `$_SERVER['REQUEST_TIME_FLOAT']` does not contain a `float` (or `$_SERVER['REQUEST_TIME']` does not contain an `int`) ## [3.1.2] - 2020-04-17 ### Changed * Improved the fix for [#30](https://github.com/sebastianbergmann/php-timer/issues/30) and restored usage of `hrtime()` ## [3.1.1] - 2020-04-17 ### Fixed * [#30](https://github.com/sebastianbergmann/php-timer/issues/30): Resolution of time returned by `Timer::stop()` is different than before (this reverts using `hrtime()` instead of `microtime()`) ## [3.1.0] - 2020-04-17 ### Added * `Timer::secondsToShortTimeString()` as alternative to `Timer::secondsToTimeString()` ### Changed * `Timer::start()` and `Timer::stop()` now use `hrtime()` (high resolution monotonic timer) instead of `microtime()` * `Timer::timeSinceStartOfRequest()` now uses `Timer::secondsToShortTimeString()` for time formatting * Improved formatting of `Timer::secondsToTimeString()` result ## [3.0.0] - 2020-02-07 ### Removed * This component is no longer supported on PHP 7.1 and PHP 7.2 ## [2.1.2] - 2019-06-07 ### Fixed * [#21](https://github.com/sebastianbergmann/php-timer/pull/21): Formatting of memory consumption does not work on 32bit systems ## [2.1.1] - 2019-02-20 ### Changed * Improved formatting of memory consumption for `resourceUsage()` ## [2.1.0] - 2019-02-20 ### Changed * Improved formatting of memory consumption for `resourceUsage()` ## [2.0.0] - 2018-02-01 ### Changed * This component now uses namespaces ### Removed * This component is no longer supported on PHP 5.3, PHP 5.4, PHP 5.5, PHP 5.6, and PHP 7.0 [5.0.3]: https://github.com/sebastianbergmann/php-timer/compare/5.0.2...5.0.3 [5.0.2]: https://github.com/sebastianbergmann/php-timer/compare/5.0.1...5.0.2 [5.0.1]: https://github.com/sebastianbergmann/php-timer/compare/5.0.0...5.0.1 [5.0.0]: https://github.com/sebastianbergmann/php-timer/compare/4.0.0...5.0.0 [4.0.0]: https://github.com/sebastianbergmann/php-timer/compare/3.1.4...4.0.0 [3.1.4]: https://github.com/sebastianbergmann/php-timer/compare/3.1.3...3.1.4 [3.1.3]: https://github.com/sebastianbergmann/php-timer/compare/3.1.2...3.1.3 [3.1.2]: https://github.com/sebastianbergmann/php-timer/compare/3.1.1...3.1.2 [3.1.1]: https://github.com/sebastianbergmann/php-timer/compare/3.1.0...3.1.1 [3.1.0]: https://github.com/sebastianbergmann/php-timer/compare/3.0.0...3.1.0 [3.0.0]: https://github.com/sebastianbergmann/php-timer/compare/2.1.2...3.0.0 [2.1.2]: https://github.com/sebastianbergmann/php-timer/compare/2.1.1...2.1.2 [2.1.1]: https://github.com/sebastianbergmann/php-timer/compare/2.1.0...2.1.1 [2.1.0]: https://github.com/sebastianbergmann/php-timer/compare/2.0.0...2.1.0 [2.0.0]: https://github.com/sebastianbergmann/php-timer/compare/1.0.9...2.0.0
