The XSF provides a public list of XMPP implementations on its website. For this list to be useful, it should contain up-to-date information about up-to-date software. To achieve this, the XSF Board has decided that all implementations have to reapply once per year, to ensure that they are still actively maintained and that the listed info is accurate. This is a purely formal process, though we encourage implementors to follow the current compliance suites.
If you have an entry in one of the lists, please create a pull request as desribed in the README before the 1st of May 2017. There is an example commit that can be used as a reference. Software that is not updated until that date will be automatically removed from the listing. Alternatively, you can ask in the jdev MUC for a manual update of your listing.
Please also ensure that you repeat this step in the following years.
