We started drafting every new issue in the XSF Github repository. We are always happy to welcome contributors. Do not hesitate to join the discussion in our Comm-Team group chat (MUC) and thereby help us sustain this as a community effort.

You have a project and write about it? Please consider sharing your news or events here, and promote it to a large audience! Even if you can only spend a few minutes, these would already be helpful! Tasks which need to be done on a regular basis are for example: - Aggregation of news in the XMPP universe - Short formulation of news and events - Summary of the monthly communication on extensions (XEP) - Review of the newsletter draft - Translations: especially German and Spanish

:de: The XMPP client Dino is one out of three projects which were awarded with the 10th Thomas Krenn Award.

Michał Piotrowski wrote an article on how to quick start Instant Messaging implementation to an app. He discusses the value of a chat feature in an app, scalability, customising and common mistakes: 'Choose your XEP, and choose wisely.'

:fr: Linuxfr.org user Space_e_man proposed his short overview of Quicksy the easy XMPP based libre instant messaging platform. While the article itself concentrates on the reasons why it should be prefered to other proprietary solutions, the comments of linuxfr.org users, as usual, bring a lot of various points of view, as well as alternatives.

Video

:es: Conociendo XMPP - The 'Comunidad Latina de Tecnologías Libres' had an online introduction to XMPP for users back in April 2020. We would like to point you to the video, even if it is a bit late. They also offer a user chat reachable under this (short and handy) address comunidadlatinadetecnologiaslibres@chat.disroot.org.

Daniel Gultsch and Holger Weiss had a virtual talk on their A/V implementation in Conversation and they described the technical details. The session was finalized with a second talk by eta who defined love by this formula: Asterisk + XMPP = <3

:de: Prof. Dr. P. Löbbecke spoke in a virtual talk about "Freie Messenger - Sichere Kommunikation" ('Free Messengers - Secure Communication') which also included XMPP (German).

Software news

Clients and applications

Gajim 1.2.0 has been released. More than a year after the release of Gajim 1.1.3, it is finally time for Gajim 1.2. A year put at use to develop new features, clean up old code, and fix bugs. Highlights of this release are (amongst others): improved group chat system, completely rewritten network code, and a new account creation assistant. And there is much more to discover. Gajim Development News: June already brought Gajim 1.2, python-nbxmpp 1.0, and many plugin updates. But there is more: Blind Trust Before Verification for OMEMO, drag and drop improvements, and a new translation service for Gajim.

Anu, the main developer of Monal, pushed new beta builds out for iOS and Mac - thanks to Thilo's and Friedrich's efforts, there are new debug features included. He asks to supply debug logs for existing issues, where possible.
