= Security Recommendation =
Zimbra would strongly recommend the customer to review whether the Proxy Servlet is configured to allow a particular host  (via zimbraProxyAllowedDomains configuration setting on each class of services), please make sure each entry in zimbraProxyAllowedDomains should be a safe and trusted host, there should '''NOT''' be any wild card entries like '''*.webex.com''' instead use specific host '''example.webex.com'''.

Any entry in zimbraProxyAllowedDomains resolves to an internal IP address (such as 127.0.0.1), an attacker could possibly access services running on a different port on the same server, which would normally not be exposed publicly. So we urge our customers to review this configuration setting to ensure that there are no vulnerabilities are introduced.

= What's New =

<br/>
<div style="padding:1%; background-color:#f68b1f; color:#ffffff; font-size:20px;">
Zimbra 9.0.0 is now fully supported on Ubuntu 20 (GA)

Download the latest Ubuntu 20 binaries from https://www.zimbra.com/downloads
</div>
<br/>

== Package Upgrade ==
<br/>
<div style="padding:1%; color:#f68b1f;font-size:20px;" >
* Apache has been upgraded from 2.4.46 to 2.4.51.
</div>
<br/>

== Calendar ==
* In Modern Web App, the event organizer will now be able to view the responses from the invitees in event details and on mouse hover of an event in the Calendar tab. This will help the organizer to get an overview of the responses of all the attendees without requiring to go through each event-response email.


== Web UX - Modern ==
* In Modern Web App, the user was not able to set the Bulgarian language. The issue has been fixed.


= Fixed Issues =

== Web UX - Classic ==
* In Classic Web App, an incorrect date was set when the user creates an appointment, set start date from the second week of the month with a Monthly custom recurrence rule - "The second day of every month". The issue has been fixed.
* When creating an appointment with the location and setting an "End by" date in the custom recurrent rule, if an appointment exists on the set "End by" date with the same location, then the location did not return conflict. The issue has been fixed.
* If the user composes an email and pastes an image from another email and sends it, the recipient receives the email without an image in it. The issue has been fixed.

== Web UX - Modern ==
* In Modern Web App, when using Advanced Search for searching specific document types (doc, text), incorrect results were returned. The issue has been fixed.
* Pre-requisite - Drafts folder shared with the user. If the user creates a draft, moves it into the shared drafts folder and tries to edit it, an error is encountered. The issue has been fixed.
* In the Contacts tab, when the user creates a sub-folder and tries to add a contact in it, "Not Found" error page is displayed and the contact is not added. The issue has been fixed.
* French translations are updated on the Settings -> Filters page.
* When the user receives a new email, the count of the unread emails is incremented but the new email is not displayed in the list until the user clicks on reload icon near Inbox or refreshes the tab. The issue has been fixed.
* If the user creates a signature from Classic Web App and sets it for "New Message" and "Replies & Forwards", then in Modern Web App, the signature was not getting displayed in Settings -> Signature -> Standard Signature. The issue has been fixed.
* When `zimbraPrefMailSelectAfterDelete` attribute is set to *adaptive* for a user, Next or Previous message was not getting selected automatically when the user performed delete/move/spam/archive operation on the message in the list. The issue has been fixed.
* When composing a message, if the user uploads the same attachment twice and tries to delete one, both the attachments got deleted. The issue has been fixed.

== ZCO ==
* Corruption in the user's profile property which stores the ZDB path causes Outlook to crash. The issue has been fixed.

== NG Mobile ==
* Fixed a bug that caused the PARTSTAT field of an invitation to be wrongly set as NEED-ACTION on accepting one appointment via Exchange ActiveSync. This bug caused the appointment not to be shown via CalDAV.

== Zimbra Connect ==
* Now every icon in Connect has an alternative text, a title and a label to improve accessibility.
* Fixed a bug that loaded a Matomo instance on log into Zimbra, raising an HTTP 404 bug. Now Matomo is no more loaded on login.
* Text paste on the conversation component will now work after upgrading Chrome to version 92.
* Improved the download of a file from one-to-one chat that suffered casual failures due to buffer issues. Now, the possibility of a file download failing has been drastically reduced.
* Information regarding the mute state of a conversation, such as groups or spaces, is now deleted when the user leaves it, whether he leaves the conversation or is being kicked by it.
* Updated logs for ChatAutoCleanup procedure.
* Video reference will be cleaned after every span of view mode.
* Removed secondary bar on external meeting and updated year in the external access login page.
* Now meetings on the external tab require login if the domain is different from the user’s domain.
* Now mini chats are automatically closed when the user is removed from the conversation or the conversation is removed.
* Changed meeting action name from "Mute for All" to "Mute".

== HSM ==
* The default behaviour of the mailbox move now will not move the backup from the source server so the operation will take less time.

== NG Auth ==
* A new widget *Mobile Password* has been added to the Zimbra Admin so the admins can manage mobile passwords from the GUI.

== NG Backup ==
* The doPurgeMailboxes operation now marks as deleted mailboxes the ones that are moved to other servers. This makes the Backup purge operation clean the data left after by the move operations too.


= Known Issues =
* None
