New Slow Channel Release Version 40.10.10

The new Slow Channel release version 40.10.10 has a long list of innovative features, but most importantly, this release includes a new, simple and yet powerful user experience making Webex Meetings more intuitive and easier to use. Another big enhancement in this release are training features, like virtual breakout sessions, the cohost role, and additional mute controls.

To learn how to upgrade to this new Slow Channel release, read more about the Webex Software Channels here.

New intuitive and simple user interface:

Enhanced Preview Window – Easily adjust audio and video settings in your new, larger preview window by using contextual menu options that are now above the Join Meeting button.

New In-Meeting Controls – New way to access meeting controls by making them always available at the bottom of your screen where they won't cover video or shared content.

Essential meeting controls remain in the center for easy access, while panel controls - Participants and Chat - are moved to the right, where the panels open when selected.

The buttons are more intuitive, with universally recognizable icons and text labels with shortcut menus so users can easily change in-meeting settings without skipping a beat.

Hide the Control Bar - When not in presenter mode, you can now hide the bottom control bar by mousing over the control bar to reveal the "Hide control bar" button, or by going to the View menu. You can also use CTRL+SHIFT+Q to hide or show the controls.

Themes – You can choose whether you want to view the meeting window in the standard Light Theme or the brand new Dark Theme, available from the View menu. Reduce eye strain by choosing a theme that works best with your lighting conditions.

Video Layout Enhancements for the Desktop App - We've made some exciting improvements to the video layout when joining meetings and events. Things to know about this more interactive and intuitive experience:

  • In Meetings, Grid view is now the default when no content is being shared. This provides a more collaborative feeling.

  • Events will continue to default to the Active Speaker and Thumbnail view.

  • Admins can now set the default video views (when no content is being shared) for meeting and events on their site.

  • Users can still change the view to Active Speaker video view or Active Speaker and Thumbnail video view from the controls in the upper right area.

  • Users will see that their self-view is now shown as part of the other participant videos for a more natural experience. If you prefer to float your self-view instead, simply click "Show my self-view in a floating window."

  • Users may hide non-video participants to focus specifically on those people who have video turned on.

Grid view is still limited to showing a maximum of 6 video system video streams simultaneously at any given time.

Training Features Coming to Meetings

Video Breakout Sessions - With brand new video breakout sessions, you'll be able to enhance virtual training for your organization or classroom or make collaborating in small groups easier. As a host, you'll be able to create multiple breakout sessions and automatically or manually assign attendees.

Cohost - Webex is also introducing cohosts to help manage meetings and breakout sessions. Cohosts can mute attendees, invite and remind participants, manage the meeting lobby, and more.

Enhanced Mute Controls and Audio Privacy

Easy to find Mute All and Unmute All Button - The Mute all and Unmute all buttons are easier to find, right at the bottom of the Participants panel.

Allow Participants to Unmute Themselves - In meetings, by default, when you mute another participant directly through Mute all or Mute on Entry, those participants can manually unmute themselves. While this is great for smaller, more conversational meetings, larger meetings and classrooms may require more moderation for when attendees are allowed to unmute.

In this update, hosts, and cohosts can now choose whether or not participants are allowed to unmute themselves. When this setting is unchecked, participants’ Unmute buttons will be disabled.

Mute All with Mute on Entry - When you click Mute all, it will also turn on Mute on Entry by default, to make sure that anyone joining the meeting late will also be muted from that point forward. Similarly, when you click Unmute all, it will automatically turn off Mute on Entry. This makes for a much more intuitive experience when managing mute in your meetings. You can still choose to turn on or off Mute on Entry independently.

Unmute and Audio Privacy - Now, when a host or cohost unmutes a participant, that participant will be given a prompt to unmute, instead of being unmuted directly. This helps to prevent meeting distractions or catching others by surprise if they weren't expecting to be unmuted.

Remove Background Noise

Continue collaborating without noisy background disruptions. When the Remove background noise setting is turned on, your desktop app will remove your barking dog or home improvement project noise, while enhancing your voice.

There are many more features which will become available as part of this Slow Channel release. Refer to the “What’s new in the Webex Meetings”, What's New for the Slow Channel of Cisco Webex Meetings.

All the enhancements released in July (40.7), August (40.8), September (40.9), and October (40.10) 2020 are now included in 40.10.10 Slow Channel version.


New Slow Channel Release Version 40.6.8

The new Slow Channel release version 40.6.8 offers a giant leap in the amazing experience and capabilities available to Slow Channel users. In this release, our Slow Channel customers can now deliver amazing new Webex meetings capabilities that will delight end users and administrators. And you could read more about the Webex Software Channels here.

The key highlights of this release are:

  • Background Blur and Replace - Users can now blur or change their background by choosing from a selection of Cisco provided virtual backgrounds when joining Meetings and Events from Mac and Windows.

  • Fastest and Most Intuitive Join Experience Yet - Joining Webex Meetings is significantly faster - with fewer clicks and less time needed to get into your meetings! See Explore the Latest Webex Meetings Join Experience for Desktop for more information.

  • Webex Assistant for Webex Meetings - The AI powered Webex Assistant for meetings interacts with users with voice commands and helps with taking notes, action items, and reminders. See Cisco Webex Assistant for Webex Meetings for more information.

  • Live Streaming to Any Platform in Events - Live stream your Events and connect with large audiences. See Live Stream Your Webex Meetings or Events for more information.

  • Powerful Troubleshooting and Diagnostics - Administrators can now diagnose and troubleshoot meeting related problems in real-time. With the ability to see the audio, video and sharing quality of the meetings in progress, administrators can analyze the root cause of any issues that could prevent the users from getting the best Webex meetings’ experience. See Advanced Diagnostics and Troubleshooting in Control Hub for more information.

With the availability of the new Slow Channel release, all versions of previous lockdown versions 39.5.x will reach end-of-support on Aug 14, 2020. Cisco will no longer provide any patches or bug fixes on 39.5 release, after Aug 14, 2020. Additionally, 39.5 release will also reach end-of-life on November 13, 2020. Any sites that have not been updated to 40.6.8 or later by November 13, 2020 will be automatically updated to the latest available Slow Channel release version at the update time.

How to Update Your Site with the New Release

We are certain that you are as excited as we are to update to the new Slow Channel release and boost the collaboration experience in your organization. Cisco Webex Control Hub, or the Webex Site Admin portal provides functionality to self-upgrade your site with just a few clicks. Please read Software Channels for your Cisco Webex Meetings Business Suite for more information.

If your site is managed by a Cisco Collaboration partner with Cisco Webex Control Hub, your partner may have disabled the self-upgrade functionality. In this case, please contact your partner for updating your site.

Other Announcements

  • Classic View Deprecation for Meetings - Starting with the Webex Modern View 40.9 update, we will be deprecating our Classic View portal for all Webex Meetings capabilities. Customers will continue to have access to the Webex Events and Webex Training capabilities, however they will no longer be able to access their Webex Meetings-specific functions through the Classic View interface. See details for What's Supported in Modern View.

  • End of Support for Windows 7 and Internet Explorer 10

    Update - Extending Support for Windows 7

    With the September 2020 (40.9) update, we announced the end of support for the Windows 7 operating system. We will now continue Windows 7 support on Mozilla Firefox, Google Chrome, and Microsoft Edge through June 2021. Cisco will continue to provide bug fixes and updates for Windows 7 wherever possible.

    For Windows 7 customers who use Internet Explorer, Cisco will support Internet Explorer 11 until Microsoft declares its end of life. To have the best meeting experience possible, plan to upgrade your operating system and browser to the latest versions.

    In the upcoming 40.9 update, Cisco Webex will officially end support for the Windows 7 operating system and the Internet Explorer 10 browser.

    Cisco will no longer provide bug fixes or updates for this operating system and browser. While users on these platforms will not be prevented from joining or starting meetings for now, we can no longer guarantee a fully functional operation. To have the best meeting experience possible, plan to upgrade your operating system and browser.

    Please note that we are actively working on establishing dates to prevent the users on these platforms from joining Webex in future. We will provide advanced notice once we have the dates.


See the participants' view of what you’re sharing

When you start sharing a screen, application, or your meeting window in Webex Meetings or Webex Events, you can now see the participants' view of what you’re sharing from the controls at the top of your screen. Hover over and click the bottom of the controls to show the view again at any time.

There’s no more second-guessing whether you’re sharing, and you’ll be confident that attendees are seeing the right content.

Guest users can edit their name or email address from the Preview window

When joining a Webex meeting or Webex event, we've made it easy for guest users to change their name or email address directly from the Preview window, without having to go back to the pre-meeting window of the Webex Meetings desktop app. Just hover over your name and click to change the information.


Email Template Changes

When a user schedules a meeting using the Cisco Webex site meeting scheduler, the email invite sent to the host contains the host key that can be used to start the meeting or claim the host role in the meeting. With the 40.4.10 update, instead of the host key being available in the email, users will now see the message shown below.

If you are a host, go here to view host information.

The following email templates will include this change:

  • Meeting Reminder to Host

  • Meeting Reminder to Host_PCM

  • Meeting Reminder to Host_CMR

  • Remind mail via Phone For Host_PCM

  • MC MeetingInfo For Host(Productivity Tools)

  • MC MeetingInfo For Host

  • Meeting Information Updated

  • Meeting Information Updated_PCM

  • Meeting Information Updated_CMR

  • Meeting Scheduled

  • Meeting Scheduled_PCM

  • Meeting Scheduled_CMR

This change is necessary to streamline the email templates and provide the same experience to hosts and attendees, whether the meeting is scheduled from the Cisco Webex plugin or add-in for Microsoft Outlook, or from the Webex site meeting scheduler.

This change also protects the host from losing the host key and control of the meeting, in case the host accidentally forwards the email invite.

This change will not affect the customized email templates on your site. If you have customized any of the listed email templates, Cisco recommends updating both the HTML and Text versions of the templates as follows:

  • Remove the line, Host Key: %Hostnumber%

  • Add the new parameters %HostKeyUrlHtml% (for HTML) and %HostKeyUrlText% (for Text)

This change will take effect on dates different than the availability dates of 40.4.10 on your site. The schedule for this change is given below, based on your site’s cluster.

B June 1, 2020
AI, AW, IC June 2, 2020

A maintenance patch has been applied to the WBS39.9.1 desktop app update. This patch requires users to upgrade their current app version. This upgrade is automatic, and is applied the first time a user hosts or joins a meeting on the site.

Based on feedback received on our Fastest Webex Meetings Join Experience that was delivered in the WBS39.8 update, this maintenance patch includes minor adjustments to help users enjoy the experience even more. The changes are as follows:

  • The join meeting dialog shows new text for joining using a video device. It also shows a tool tip when users hover over Use Video System.

  • Users who see the Join Meeting dialog for the first time see an option to walk through the dialog.

  • Users see a tool tip when they change their audio or video status. These tool tips also appear larger.

Cisco now publishes monthly maintenance and upgrade schedules for all clusters.


A maintenance patch has been applied to the WBS39.8.4 and WBS39.9.1 application updates.

See the WBS39.9.1 section of the What's New in Webex Meetings Suite (WBS39.6 and Later) for more info on the changes included in this update.


In our previous WBS39.8 update, we announced a faster and more intuitive way to join meetings, where users could skip audio and video previews when connecting to a meeting. However, with this WBS39.8.3 update, we're temporarily disabling this feature in Preferences > Meeting Join Options. We plan to re-enable this feature in a future update.

See the Open and Resolved Bugs (WBS39.6 and Later) for more info on other resolved bugs in this update.


In our previous WBS39.8 update, we announced a faster and more efficient way to join meetings. However, due to an error, users would receive an error message when selecting a scheduled meeting or trying to start an instant meeting. We're fixing this error in our WBS39.8.2 update.

See the Open and Resolved Bugs (WBS39.6 and Later) for more info on other resolved bugs in this update.


In our previous WBS39.8 update, we announced that Webex Meetings would support macOS Catalina (Version 10.15).

We're also releasing Catalina support in this WBS39.7.7 update, for users who want access to Catalina before being upgraded to WBS39.8.

See Support for Cisco Webex Meetings for macOS Catalina for caveats and more info on support for earlier versions of Webex Meetings.

See the Open and Resolved Bugs (WBS39.6 and Later) for more info on other resolved bugs in this update.

See the Webex Meetings Suite Lockdown Announcements for more info on the WBS39.7.7 temporary lockdown removal.


In our previous WBS39.7 update, our original intention was to simplify our Webex Events email template customization, so that users could:

  • Edit event titles

  • Edit the Reply To Email template

  • Add a header image to an invitation

  • Add a footer image to an invitation

No other customizations would have been supported. In addition, this update would have applied to all existing Webex Events email templates, not just the ones modified with a new look and feel.

Existing users who haven't modified their customized templates wouldn't have seen any changes, as we wouldn't have changed any existing template configurations. However, if these users decided to reset their invite to a default template, or continued customizing a template, then they would no longer have access to their old customization options.

Both slow channel and latest channel users received this change.

Both Classic View and Modern View users received this change.

However, we're making changes to our original plan. Starting with our WBS39.7 EP update, we're enabling support for customizable templates, with this new behavior:

  • Existing customers who haven't modified their customized templates continue to not be impacted.

  • Users who wish to continue to customize their templates should revert to the default email templates first, and then update their templates again.

  • Users will no longer be able to add a header or footer image to their invitations in a direct upload, in the way that existed before and up to WBS39.7. However, starting from WBS39.7.4, users are able to incorporate header and footer images by changing the HTML code directly while customizing a template.

Both slow channel and latest channel users receive this change.

Both Classic View and Modern View users receive this change.

See the Webex Email Templates in Cisco Webex Site Administration for more info on changes made to these templates.

WBS39.5.13 - macOS Catalina Support

In our previous WBS39.8 update, we announced that Webex Meetings would support macOS Catalina (Version 10.15). For users on lockdown versions of the desktop app who want to access Catalina, they will need to run WBS33.6.15 or higher.

Earlier versions may be limited to using the Webex Meetings web scheduler and the web app to schedule, start, and join meetings. In general, we recommend that you don't upgrade to macOS Catalina until this patch is released.

For more info on macOS Catalina support, support for earlier versions, and caveats, see:


WBS39.5.13 Lockdown Release

WBS39.5.13 is a lockdown release. Customers looking to have updated features while minimizing the changes in their environment can lock down their Webex Meetings desktop applications to this version.

For more info about this lockdown version, see:
