Unit 1.32.1 released

[Timo Stark]

Hi, NGINX Unit community,

NGINX Unit 1.32.1 is a maintenance release that fixes bugs in the new WebAssembly Language Module
and in our NJS implementation.

*) Resolved issues

This release fixes the following issues:

**) Applications of type wasm-wasi-component can’t be restarted

Applications deployed as wasm-wasi-components can’t be restarted using the restart endpoint.

After deploying a new Wasm Component binary to disk, the restart will trigger a reload of the component
in Unit without restarting the server.

As restarts will work independently of the application type, the behavior shipped with 1.32.0 was not
right. It has been fixed in this release.

**) Unit-variables in NGINX JavaScript are constantly cached

In 1.32.0 we added the possibility to access all Unit variables form inside NJS.

As reported in GitHub issue #1169 the variables were cached and would hold the wrong value,
which is not how this feature should work. With version 1.32.1, we have fixed this issue.

Changes with Unit 1.32.1                                         26 Mar 2024

    *) Bugfix: NJS variables in templates may have incorrect values due to
       improper caching.

    *) Bugfix: Wasm application process hangs after receiving restart signal
       from the control.
