Release highlights

This release is a bugfix release which also introduces some performance improvements.

New or improved functionality

• internal logging improvements
• performance improvements in Online mode

Bug fixes

• Fixed a bug where the Zivver message would get decrypted, but the attachments not.
• When replying to a Zivver Conversation, extra white space is no longer added under the text of the message and the bottom of the message pane/attachments bar when the message is sent.
• When replying to a Zivver Conversation, a ~WRD file is no longer added to the message as an attachment.
• In-product link to the Zivver FAQ now redirects to docs.zivver.com as intended.
• When a normal message is popped out and then forwarded/replied by using the Outlook button, Outlook no longer crashes.
• When a user is not connected to the internet, the plugin no longer tries to login indefinitely, so that multiple login dialogs that remain opened with a spinning wheel are no longer created in this situation.
• Office Outlook no longer freezes when forwarding messages with large attachments (>35 MB) with the Zivver Plugin enabled and Outlook in Online mode.
• Sending dialog and the attachment pop up to inform how far the upload has progressed are now correctly displayed when adding an attachment in the plugin via the Zivver button.
• Multiple SSO login requests can no longer be triggered concurrently.
• Closing forwarded draft no longer results in .NET application error. The issue would occur when forwarding a Zivver message, upon closing the draft of the forwarded message. In this case, a .NET Runtime error would appear and Outlook would be forced to close.
• “Zivver mail to detect sent items folder” no longer stuck in Outlook.
• Sent items no longer end up as new mails in the Inbox.
• CPU load when Zivver Office Plugin is active in a Citrix environment is no longer abnormally high.
• Replying to the original message from a BCC message no longer addresses the reply to the BCC recipient.
• Attachment is no longer duplicated in the local copy every time you view the conversation.
• Unencrypted messages are not missing space in inconsistent places anymore.
• Outlook no longer crashes on Zivver SSO login.
• Icon colors in Zivver Bar are now correct.
• Read pane and compose pane are now updated directly after successful login.
• Feedback button in the Zivver menu is fixed.
• SetDecryptionHashOnEmail no longer saves mail messages twice in a row, so that saving messages in Online Mode is now faster.
