Minor Release

Zammad 5.1

ยท Ah, spring... the time for rebirth and new buds. ๐ŸŒผ What better season to bring you a brand new version of Zammad? And alas, Zammad 5.1 is here, with exciting new features such as Knowledge Base Permissions, Multiselect, and an import wizard for Kayako. Enjoy!

1. ๐Ÿšซ Knowledge Base Permissions

Let's start with a big one: The knowledge base permissions are something many of you have been waiting for! So far, user access applied to the whole database, meaning that a user of your instance could either view or view and edit the posts.

Now, these permissions can be defined on a category level. So if you have an agent with great expertise on a certain topic, you can grant them edit rights for this specific knowledge base category alone:

For example, a member of our Zammad team who knows everything about our subscriptions could have editing rights to the "Subscriptions" section of our knowledge base alone.

This way you can still ensure consistency while unlocking all the potential of your team members' expertise!

2. โœ… Multiselect

Ah, another good one! Have you ever created a ticket and found that you couldn't decide which category to assign it to? Well, that's a thing of the past now! Thanks to the new Multiselect feature you can - as the name implies - select multiple categories for the same ticket! So easy and yet so helpful... we hope you will love it as much as we do!

3. โœ๐Ÿป Shared Draft

This function has been requested again and again. Do you want to pass on a response by an agent (e.g. a trainee) to a colleague for quality assurance before sending it to a customer? As of Zammad 5.1, this is possible. Simply compose a response and instead of saving the ticket just save the "draft". The next agent can simply "load" this draft and continue working on it.

4. ๐Ÿง™ Kayako Import Wizard

If you're currently using Kayako as your helpdesk and casting sneaky looks at Zammad, who are we to blame you? Instead, we have some great news for you: The brand-new Kayako import wizard makes the transition to Zammad easier than ever before. Simply import your existing Kayako files into a Zammad instance at the touch of a button.
Seems like it's time to make your Zammad dream come true! ๐Ÿ˜‰

5. ๐ŸŒ Weblate: New Translation Tool

As you probably know, Zammad is used worldwide. In order to appeal to users all over the globe, we have always tried our best to offer our interface in as many languages as possible - currently over forty! Keeping all these translations complete and up to date as well as adding new languages has only been possible thanks to the tireless contributions of our amazing Community... aw, you legends! ๐Ÿ˜

With the introduction of a new tool, Weblate, it will now be easier than ever before to collaborate on the different language versions of Zammad. Simply click on the button below, set up an account, select the languages you can help out with, and start adding or reviewing translations.

Start translating!

6. ๐Ÿ•’ 12-Hour Time Format (AM/PM)

Lastly, we implemented a new setting that also benefits our international users: the 12-hour time format. Now organizations can choose whether they want to use the military time format (00:00 to 24:00) or the 12-hour time format (12 AM to 12 PM). The latter will now be the default setting in Zammad for English (United States). Admins can customize this setting per language.

Breaking Changes

Granular permissions may be risky

Please note that granular permissions require at least knowledge_base.reader permission and thus provide potential internal answer access.
Please refer the documentation for more details:

SSL-Settings no longer auto-dectect (inbound email channel)

E-Mail-Accounts may no longer work inbound, in case you're using email channels with non default ports. Simply edit the inbound channel and choose the correct encryption type for SSL / STARTTLS. Please refer our documentation for more details:
