Unit 1.32.0 released

[Timo Stark]

Hi, NGINX Unit community,

Unit 1.32.0 comes with a new language module for WebAssembly that supports the
WASI 0.2 HTTP world so that WebAssembly Components implementing this interface
can be hosted on Unit.

This new language module improves upon the existing WebAssembly support.
We recommend all users to use this new implementation for WebAssembly.
We consider the old unit-wasm module deprecated now.

Additionally, we have added the following features:

*) Enhanced the NJS (NGINX JavaScript) experience by making all Unit variables
   accessible from JavaScript

*) Added support for conditional access logging, to help you filter the requests
   that are logged

*) Added support for changing Unit's control socket permissions

*) Added a new variable, $request_id

       with Rack v3.0.

    *) Feature: Python bytearray response bodies for ASGI applications.
