The Zend Framework blog has posted their official announcement of the release of Expressive version 3, the latest major release for the Zend Framework-based microframework based around PSR-15 middleware.

Expressive 3 embraces modern PHP, and requires PHP 7.1 or higher. Strong type-hinting, including return type hints, make both our job and your job easier and more predictable. The ability to use all modern PHP features helps us deliver a solid base for your application.

Expressive 3 provides full support for the PSR-15 (Middleware and Request Handlers) standard. [...] Expressive 3 massively refactors its internals as well. [...] Expressive 3 provides more command line tooling and tooling improvements in order to make developing your application easier.

[...] Finally, we recognize that Expressive has changed massively between versions 1 and 3, while simultaneously keeping its primary API stable and unchanged. However, to help users find the information they need for the version they run, we have rolled out versioned documentation, with each version providing only information specific to its release cycle.

The post also lists out some of the new components including zend-expressive-session, zend-expressive-csrf and zend-expressive-hal. There's also links to more information about upgrading, community resources and a "thank you" section to several people that helped get the project to this version 3 release.
