It's been a while since there's been an update about v4 progress. Rest assured - progress is being made. Since building a framework is not a very visual thing, it's hard to post screenshots, but I figured I would post one of the current Exceptions screen. These screens only show up when the ENVIRONMENT is set to development, and provide a pretty thorough snapshot of the system at the time.
Due to the way that PHP7 treats Errors, a screen similar to this is shown for all Exceptions and Errors that are descendants of Throwable. PHP does reserve a few things that still crash and we cannot catch, but there's much less than before.
As always, this is very much a preview and may/is likely to change before any public beta is released, etc, etc.
While not a game-changing feature, it is fairly handy to have when developing.
