PKZ / CHANGELOG.mdnuW+A# CHANGELOG ## v2.18.0 * Line numbers are now clickable. ## v2.17.0 * Support cursor IDE. ## v2.16.0 * Support PHP `8.4`. * Drop support for PHP older than `7.1`. ## v2.15.4 * Improve link color in comments. ## v2.15.3 * Improve performance of the syntax highlighting (#758). ## v2.15.2 * Fixed missing code highlight, which additionally led to issue with switching tabs, between application and all frames ([#747](https://github.com/filp/whoops/issues/747)). ## v2.15.1 * Fixed bug with PrettyPageHandler "*Calling `getFrameFilters` method on null*" ([#751](https://github.com/filp/whoops/pull/751)). ## v2.15.0 * Add addFrameFilter ([#749](https://github.com/filp/whoops/pull/749)) ## v2.14.6 * Upgraded prismJS to version `1.29.0` due to security issue ([#741][i741]). [i741]: https://github.com/filp/whoops/pull/741 ## v2.14.5 * Allow `ArrayAccess` on super globals. ## v2.14.4 * Fix PHP `5.5` support. * Allow to use psr/log `2` or `3`. ## v2.14.3 * Support PHP `8.1`. ## v2.14.1 * Fix syntax highlighting scrolling too far. * Improve the way we detect xdebug linkformat. ## v2.14.0 * Switched syntax highlighting to Prism.js. Avoids licensing issues with prettify, and uses a maintained, modern project. ## v2.13.0 * Add Netbeans editor. ## v2.12.1 * Avoid redirecting away from an error. ## v2.12.0 * Hide non-string values in super globals when requested. ## v2.11.0 * Customize exit code. ## v2.10.0 * Better chaining on handler classes. ## v2.9.2 * Fix copy button styles. ## v2.9.1 * Fix xdebug function crash on PHP `8`. ## v2.9.0 * `JsonResponseHandler` includes the exception code. ## v2.8.0 * Support PHP 8. ## v2.7.3 * `PrettyPageHandler` functionality to hide superglobal keys has a clearer name (`hideSuperglobalKey`). ## v2.7.2 * `PrettyPageHandler` now accepts custom js files. * `PrettyPageHandler` and `templateHelper` is now accessible through inheritance. ## v2.7.1 * Fix a PHP warning in some cases with anonymous classes. ## v2.7.0 * Added `removeFirstHandler` and `removeLastHandler`. ## v2.6.0 * Fix 2.4.0 `pushHandler` changing the order of handlers. ## v2.5.1 * Fix error messaging in a rare case. ## v2.5.0 * Automatically configure xdebug if available. ## v2.4.1 * Try harder to close all output buffers. ## v2.4.0 * Allow to prepend and append handlers. ## v2.3.2 * Various fixes from the community. ## v2.3.1 * Prevent exception in Whoops when caught exception frame is not related to real file. ## v2.3.0 * Show previous exception messages. ## v2.2.0 * Support PHP `7.2`. ## v2.1.0 * Add a `SystemFacade` to allow clients to override Whoops behavior. * Show frame arguments in `PrettyPageHandler`. * Highlight the line with the error. * Add icons to search on Google and Stack Overflow. ## v2.0.0 Backwards compatibility breaking changes: * `Run` class is now `final`. If you inherited from `Run`, please now instead use a custom `SystemFacade` injected into the `Run` constructor, or contribute your changes to our core. * PHP < 5.5 support dropped.
