EPNix 25.11 released

[NICOLE Rémi via Tech-talk <tech-talk at aps.anl.gov>]

I'm happy to announce the release 25.11 of EPNix!

[EPNix] is a project that enables you to build, package, deploy IOCs
and other EPICS-related software by using the [Nix] package manager.
For more information about this approach,
see the [Advantages / disadvantages] page in the documentation.

This release is a little late compared to the November 25.11 NixOS release,
partly because of the end-of-year vacations,
but mostly because I just wanted to include way too much.

We have a few new packages such as `pvaPy`, `DBWR`, and `PVWS`.
We also have some upgrades, which includes:

- Archiver Appliance version 2.1
- Phoebus Olog version 5.1
- the OPCUA support module version 0.11

For a complete list of packages in EPNix,
you can have a look at our *now improved* [Packages list] page.

On the NixOS deployment side, we have a new module for configuring
the [firewall for EPICS clients and servers] (thank you Matthieu).

On the documentation side,
we have some new pages, including:

- a guide on adding [integration tests] in EPNix tops,
  in which you can start clusters of NixOS VMs
  running IOCs and simulators
- articles explaining the [different types of Nix dependencies],
  and a guide on [how to add dependencies for IOCs]
- a brand new [glossary]! (Thank you Stéphane)
- a new step by step tutorial that guides you through [Packaging the asyn EPICS support module],
as a learning resource

This is it for the announcement,
but you can find more in the [EPNix 25.11 release notes].
