|Various||The 8.8.9 release includes all fixes provided in 8.8.8 patch 1 through 6.|
|GAL||Reapplied fix for Bug 95459, improving the warnings logged for "unknown GAL op".|
|Calendar||Fixed a bug in recurring appointments where the date for a series would be changed in the originator's calendar when an invitee declined a single instance after initially accepting the series.|
|ZCO||Suppressed an informational pop-up that periodically reported "GalSync has failed 5 times", alarming users and resulting in help requests to sysadmins. This would occur when the server was busy with many sync requests from multiple users, for example. No user intervention was required, since automatic retries will eventually complete the sync.|
|ZCO||Windows Registry keys used to set up Windows Search for ZCO are now automatically checked and regenerated in the event that they are removed by a Windows or MS Office update. See more informaton in the troubleshooting section of the ZCO Admin Guide.|
|ZCO||Fixed an encoding problem during synchronization via the Zimbra Connector for Outlook that would cause non-ASCII (e.g. accented characters such as the "é" in Québec) to be misinterpreted and changed (e.g. to QuÃ©bec).|
|S/MIME||Changed hashing algorithm to SHA-256 instead of MD5 to address compatibility with other email clients (e.g. Gmail, Thunderbird) that previously reported problems with Zimbra's digital signatures.|
|LDAP||Backing up a live LDAP database incurred a risk that when loaded on a new machine it could be out of sync if LDAP changes had occurred during the backup. This condition may not become apparent until a MOD causing a REFRESH occurred, which could cause an outage. This risk is now mitigated.|
|Chat Zimlet||Users without a local video or audio source were not able to join videocalls. When these conditions are detected, the Zimlet now adds empty streams to allow the user to establish the connections to other participants.|
|HSM||Logs no longer include possibly sensitve S3 access information.|
|HSM||If the HSM (aka Powerstore) module licensing expired, no custom ZeXtras stores were accessible. Now the StoreManager is always registered to allow volume access, but further commands and operations will be denied until the licensing is brought up to date.|
|HSM|| Blobs were not being deleted from the previous source volume immediately following a move operation, but were moved to the |
|NG Backup|| The |
|Admin Zimlet||The admin UI would throw up an errer and could become unstable after opening or editing an alias. Console errors indicated an Uncaught TypeError. This has been fixed by allowing for possibly empty values in id and name fields of aliases.|
|Chat Server|| The chat service |
|ZCO||If the primary (Default) account persona is set up in ZWC with Send-on-behalf-of, ZCO / Outlook will disregard the setting and send email using only the primary account email for that persona. Users are recommended to configure Send-on-behalf-of only for secondary accounts in ZWC, to ensure consistent behavior in both interfaces.|
|HSM Admin||When configuring HSM as primary storage, the warning popup reporting that the required path does not exist cannot be dismissed. The browser must be reloaded at this point to continue. There is no permanent operational impact.|
|Docs||Logs from the separate 'docs' server are not forwarded to ZCS for monitoring. As a result, 'docs' may be reported as not running and be shown Out-Of-Service in Home - Monitor - Server Status in the admin console.|
