Kopano Core & Archiver 8.3.1 final is now available

As the name implies Kopano Core sits at the heart of every Kopano environment and is therefore a key figure in our promise to deliver stability and extensibility of Kopano’s proven communication platform. Kopano Archiver provides a way to minimize primary mailboxes by moving older messages to slower (and presumably cheaper) storage. Kopano Archiver consists of additional components that allow running Kopano servers dedicated on slower storage for archived messages whilst keeping them available transparently to the user.

Bugfix release

In version 8.3.1 we provide selected bugfixes, which have been reported by customers to us within the last days. Specifically, the following fixes have been made:

  • server: fix of memory leak
  • inetmapi: do not force HTML when use_tnef is set to „minimal“
  • spooler: drop excessive locking for CleanFinishedMessages
  • spooler: remedy wrong condition variable waiting function
  • spooler: cure a use-after-free
  • spooler: custom bounce message text for forward_whitelist_domain
  • spooler: issue reading certificate files
  • backup: batch storage updates

Spooler under load and/or memory pressure

Under certain circumstances, spooler could create a deadlock in which it stops responding, especially under high load or memory pressure. The fixes we’ve made fix this behavior to make sure that spooler continues to operate correctly also under higher load.

HTML forced messages with use_tnef

A small bug which was introduced in combination with the switch to the most recent libvmime version including the adoption with its new interfaces in the event use_tnef was set to minimal. With 8.3.1 beta we already resolved this behavior and do not forcibly generate an HTML representation of plain text mails.

Debian 9 packages

The Debian 9 release is only a few days old, but we already received quite some requests for packages for it. While we are already building packages for Debian 9, these have not yet passed a full QA set and therefore cannot be fully supported by us. For those who are ancious to get started anyways we have in any case already included them with our “limited” supported repository. This can be accessed from https://download.kopano.io/limited/core:/final/Debian_9.0/.

Where do I get the packages?

The packages can be found in the repositories, the portal and the download server (all require login). You can find the latest development version of Kopano Core on the community download site.

We are really looking forward to your feedback on this version as this will help us further improve and adapt Kopano Core and Kopano Archiver to fit the required needs best. Let us know what you think by sending an email to feedback@kopano.com, or posting over at our new Kopano Forum.
