What's New

NOTE: Beta features are not supported and should not be installed on production systems. Beta modules have been provided for evaluation in lab environments only.


Zimbra Video Server (BETA)

  • The Video Server (BETA) is a WebRTC stream aggregator that improves Zimbra Connect’s performance by merging and decoding/re-encoding all streams in a meeting. Refer to the admin guide for instructions on installing the Video Server on the systems.

We are nearing the end of our extensive QA cycle for these package upgrades. Watch for the GA announcement in an upcoming patch release.


Announcing GA


The following packages are now GA:

Zimbra OpenSSL 1.1.1h compatibility issues with some kernel versions (4.8 and 4.9)


On Ubuntu-14 and CentOS/RHEL-6 with few kernel versions like (4.8, 4.9), the Zimbra Proxy and LDAP services failed to start due to compatibility issues with OpenSSL 1.1.1h. The issue has been fixed.
Note: Fixed above issue in updated Patch version today dated Apr 02, 2021 which was reported on the first version of 8.8.15 Patch 20.

Impacted deployments can fix the issue by following the patch installation steps again.


Platform

  • Upgraded OpenSSL from 1.0.2t to 1.1.1h and added FIPS support.

Zimbra Docs

  • New version of Docs Server is available and can be found on the Network Edition Downloads page.


Fixed Issues

Platform

  • When using DKIM Signing with TLS1.3 beta packages, opendkim service was crashing. The issue has been resolved.
  • The SSL freelist can be exploited in the current version of zimbra-openssl which has been fixed with the upgraded Openssl version 1.1.1g
  • Zimbra Proxy now supports and is enabled with http2 protocol capabilities.
  • Intermittently, there were memory corruption issues encountered during IMAP/POP3 connections. The issue has been fixed now.
  • When synchronizing shared calendar via CalDAV, if the '+' character is present in the event then the sync failed. The issue has been fixed.
  • postfix-logwatch was not able to generate the report. Upgrading postfix-logwatch from 1.40.01 to 1.40.03 fixed the issue.
  • The administrator was unable to save the global configuration data when an Ephemeral storage was used. This is fixed now.
  • When zimbraReverseProxyStrictServerNameEnabled is set to TRUE, the Zimbra Proxy service failed to start. The issue has been fixed.
    Note: Fixed above issue in updated Patch version today dated Mar 31, 2021 which were reported on the first version of 8.8.15 Patch 20.

ZCO

  • Outlook may go in non-responsive state for a few minutes while opening HAB Group node that have more than 5000 accounts.
  • When a user has a signature and sends a message using Apple Mail with attachments, the signature is also sent as an attachment and is not a part of the message body. This issue is due to a bug in the Apple Mail client.

NG Auth

  • Added more information to the log when an invalid credential is used.

NG Backup
