PHPStan then attributes checked exceptions thrown by the callback to the caller.

A generator whose parameter is typed Dependencies gets the object, any other
keeps the array by reference. load(), save(), bulkSave(), wrap() and
OutputHelper::end() accept the object as well. An array is converted to it, so
an unknown key, a condition of clean() given as a dependency or a value of a
wrong type now throws instead of reaching the storage. Storages still get the
array.

A missing item is generated by one process, the others poll until it appears.
The lock expires after $lockTimeout seconds (30 by default), so a crashed process
does not block the item, and is released only by the process still holding it.

The lock spanned two calls, lock() and the write() or remove() releasing it,
so a network storage could not implement it safely. Now the storage runs the
generator of Cache::load() under its own lock and releases it in finally.

FileStorage reads the item again under the lock, so a process that found it
missing while another was generating it no longer generates it a second time.
A failed generator or a missing journal leaves no empty file behind, and a
generator generating its own item throws instead of waiting forever for the lock
of its own process.

Cache::save() with a closure is deprecated, it runs the closure without a lock.

Without vendor/ it knows nothing of the classes of the libraries, so a call of a deprecated method passes unnoticed.

A paired {label}, a label or input with attributes and n:name need an Html
element; a control returning a string from getLabel() or getControl() ended
with a fatal error on a string. A plain {label} and {input} still render it.
