Laravel 10: types, processes, and Pennant feature flags

Released on 14 February 2023, Laravel 10 kept the annual major cadence going with stronger typing and new first-party platform primitives.
Laravel 10 did not try to reinvent the framework. Instead, it extended the steady modernization work from 9.x and concentrated on features that improve real code quality without forcing broad rewrites.
The most important additions were argument and return types across the application skeleton and framework stubs, the new `Process` facade for starting and interacting with external processes, and Laravel Pennant as a first-party feature flag system.
That combination matters because it sharpens both correctness and operations. Better types make generated code less ambiguous, while Pennant and the process layer give teams stronger primitives for staged rollouts, automation, and system integration work.
