1 Introduction
This document provides release notes for:

the PC Client and Mac (OS X) Client v1.3 (build 1.3.54), and

iOS Clients v1.3 for iPhone and iPad.
Note: Some builds were not published.
The document is divided into sections: this general introduction and then one section per client.
1.1 New Features
Upgrading your Acano server to v1.6.x and your Acano Clients to v1.3.x, delivers the following
new features to your Acano Solution:

Ability to adapt the client through permission settings (user-levels) in the Acano Server API.
For example:

Enable users to create coSpaces

Enable an individual to add or remove members or chat in the coSpace

Enable users to delete messages in the coSpaces that they create
A button is displayed to coSpace members who have the canDeleteAllMessages
parameter set to true via the API. However, the default value is false, and therefore not
everyone sees this button. See the Acano Solution R1.6 API Guide for details.

Improved user experience when the connection temporarily drops. The "persistent
connection" features means that if the connection to the Acano server drops, your content is
still visible. However, you cannot post messages, make calls or create new coSpaces while
the link is unavailable.

Support for multiple Call Bridges, and the selection of the optimum Call Bridge depending on
the optimal media path.

Pictures allowed in the coSpace chat; simply copy or type the link to an image into the chat,
and the image appears. A preview is shown if the image is within text.
Note: If you are using v1.3 clients then ensure that the XMPP certificate, supplied by the Acano
server, contains the domain name as a Subject Alternative Name (SAN) within the certificate, in
addition to the Common Name in the certificate being the same as the FQDN. Otherwise, PC
and Mac Clients will display a warning message, before allowing the user to continue.
1.2 Feedback
We would like feedback on this release. Please ensure that one person at your site collates
issues and acts as the single point of contact for Acano support.
When providing feedback there are two types of logs that are useful:


If you experience a crash, you should get a popup window with crash debug information.
Copy and paste that to an email in the support case.

If you have other issues such as poor quality audio and you’re using one of the clients that
have a debug facility, press the Debug button whilst the issue is happening, save the file
and email it to the support case.
If you encounter any issues, contact [email protected].

2 Mac Client v1.3
This section of the release note describes the v1.3 (build v1.3.54) release for the Acano solution
Mac Client.
Specific bug fixes are given later in this section.
2.1 Installation Instructions
1. Click on the Mac Client Download link on the Acano Support page.
2. Open the dmg file and drag the ‘acanoclient’ icon into the Applications folder within the
window that opens up.
3. If you already have an older version of the Acano Mac Client installed in the Applications
folder, a prompt asks whether you want to replace it with the new one that you are moving.
Select Replace.
This will overwrite the previous version and if, for example, you have a shortcut in the dock
this will now automatically launch the new version.
Note: If you first remove an older Mac Client from the Applications folder and then copy the
new one into it, clicking on the dock shortcut no longer works and the icon becomes a
question mark because the icon still searches for the previous application version.
Launching the new version from the Applications folder will result in a separate dock
shortcut being created. Follow the instructions above to avoid this.

diagnostics in full screen
mode

presented with a grey desktop. Exit full screen mode (from the
OS X menu bar) and click back onto the client.

closed, but is hidden behind the main Mac Client. This dialog
remains until the Mac Client is closed.

Slideshow mode in
PowerPoint doesn't work
Previously, slideshow mode in PowerPoint didn't work because

screen menu. An application that you wish to share needs to be
maximized, and then the Acano client should be tabbed in front
of this.

image appears. This happens both when opening the user menu
to show self-view and when joining an empty coSpace.

4 iOS Client v1.3
This section of the release note covers the iOS Client v1.3 for the iPhone and iPad.
4.1 New features since v1.2
In addition to the new features listed in section 1.1, the following features have been added or
altered since iOS Client v1.2:

Indicator for unread messages has been added

The behavior of links in the message board has changed
o
If the first URL in a message is to an image, then the image is displayed after the
message
o
If the first URL in a message is not an image, then the client presents a summary
of the link's contents
Both behaviors are turned off by default. Enable these behaviors through the Acano
settings in the Settings app.
4.2 Installation Instructions
1. Install or update the Acano app from the App Store, and open it. If you have enabled
Automatic Downloads in the Settings app, then the Acano app will automatically update.
4.3 Differences in iOS Clients v1.3 from PC and Mac Clients
This section identifies the key differences in behavior in the iOS v1.3 Client for iPhones and
iPads from the v1.3 client for PC and Mac.
Using the iOS Client, you cannot:

Present content

Create or edit contacts. However, contacts found by searching the directory can be
added to Favourites

Provide a URL, identifier or passcode for a new coSpace or edit those properties of an
existing coSpace

Access call, coSpace or contact information from the management view
In addition:

Unread message counts for coSpaces and contacts are only shown in the list (not on the
navigation bar buttons)

There is no video on the iPhone

There is no access to the membership list of a coSpace, or the participant list of a call
from the iPhone management view

Tapping a participant's name on the in-call participant list will not cause that participant to
