[ANNOUNCE] Apache ManifoldCF 2.27 released

[Piergiorgio Lucidi <pi...@apache.org>]

The Apache ManifoldCF team is pleased to announce the 2.27 release.

Apache ManifoldCF is an effort to provide an open source framework for
connecting source content repositories like Microsoft Sharepoint and
EMC Documentum, to target repositories or indexes, such as Apache
Solr, Open Search Server, or ElasticSearch. Apache ManifoldCF also
defines a security model for target repositories that permits them to
enforce source-repository security policies.

== Release Notes

This is the first release of ManifoldCF using the GitHub repository, a
big part of the effort was spent converting our release scripts from
Python to GitHub Workflows / GitHub Actions.
This will bring a huge benefit for the overall community because now
we can manage Pull Requests from GitHub in the standard way.

Our Maven artifacts are now published in the ASF Nexus repo and they
are available publicly:
https://repository.apache.org/#nexus-search;quick~mcf

We also have official Docker Images published in the Docker Hub:
https://hub.docker.com/r/apache/manifoldcf

We are also pleased to introduce the ManifoldCF SDK, a first version
is available in order to facilitate the development of connectors and
extensions on top of ManifoldCF.
The SDK will create the extensions JAR using the public Maven
artifacts and it will deploy it in our official Docker Image creating
your own ManifoldCF container:
https://github.com/apache/manifoldcf-sdk

The website now is managed using GitHub including all the generated
HTML templates, this due to the deprecation of the ASF Pelican CMS.

Finally we also solved some Ant and Maven build issues, updated the
footer UI and other little bug fixes. Below all the solved issues:
