OTRS Community is nu: Znuny – The OTRS Community Edition Fork

OTRS Community is nu: Znuny – The OTRS Community Edition Fork

In december 2020 heeft OTRS AG onverwacht aangekondigd dat de ondersteuning van de ((OTRS)) Community editie door OTRS AG zal worden beeindigd. OTRS AG zal geen updates, patches en security fixes meer uitbrengen.

Znuny GMBH zal vanaf heden het onderhoud van de software voor haar rekening nemen en heeft een Fork van de OTRS Community Edition uitgebracht onder de naam: Znuny LTS (long term support). Znuny LTS is volledig gebaseerd op de source code van de OTRS Community Edition en 100% compatible. Hierdoor is de voortzetting van de software gewaarborgd. Znuny is en blijft open source software.

Znuny GmbH is een belangrijke speler in de OTRS Community en wordt geleid door een van de oorspronkelijke oprichters van OTRS.

Lees hier meer over het besluit van Znuny om het onderhouden van de OTRS Community applicatie over te nemen.

OTRS Support zal voor haar klanten geen OTRS Community Edition meer gebruiken aangezien hier geen updates meer voor zullen uitgebracht maar vanaf heden Znuny LTS.

Basic Authentication Office 365.

Microsoft zal midden 2021 stoppen met support op basic authentication voor Exchange Online. Dit betekent dat e-mail niet op de huidige manier kan worden opgehaald en zal stoppen met werken.

OTRS SUPPORT heeft een plugin beschikbaar die MS Graph authenticatie ondersteunt zodat uw installatie probleemloos blijft werken.
