Unit 1.30.0 released

[Timo Stark]

Hi NGINX Unit community,

We are happy to announce Unit 1.30.0! This release brings a new level of
sophistication to Unit’s configuration and enhances logging controls.

*) Incoming URIs can now be rewritten as part of the routing process.

*) Configuration values can now be evaluated by referencing JavaScript
   modules and functions.

*) Each application can now write its diagnostic output to log files
   (or not at all).

*) The steps taken by the router can now be logged for diagnostic purposes.

Alongside 1.30.0, we are pleased to present Docker official Images for
NGINX Unit and the new OpenAPI specification for Unit’s control API.

Changes with Unit 1.30.0                                         10 May 2023

*) Change: remove Unix domain listen sockets upon reconfiguration.

*) Feature: basic URI rewrite support.

*) Feature: per-application logging.

*) Feature: conditional logging of route selection.

*) Feature: support the keys API on the request objects in NJS.

   "Server" header field.

   the bug had appeared in 1.29.0.
