EchoSystem 5.5 Service Pack 17 (5.5.2017-6.29.x) Release Notes

On this page:

Introduction

This document covers EchoSystem 5.5, Service Pack 17 (5.5.2017-6.29.x).

Services version is:

5.5.595718452

You can refer to this version as "EchoSystem 5.5 Service Pack 17" when working with Echo360 Support.

Service Pack 17 for the Echo System Server version 5.5 is an update to the release of the EchoSystem version 5.5 and addresses the issues listed in the Fixes Included section below. This is the most advanced and reliable version of the Echo System Server released yet, containing several enhancements and fixes for our content migration tools. Please contact Echo360 support if you have any questions regarding upgrade or migration.

As announced in December of 2015, all future development will be dedicated to our Echo360 cloud platform after June 30^th, 2017. As such, this will be our final installer release of the Echo System Server. By focusing on our new, modern platform, Echo360 will continue to lead the way in education for video, engagement, and analytics.

New Features and Updated Support

New ESS to Echo360 active learning platform Migration Updates! See the Migration Guide, as well as the fixes listed below for further details.

The Migration -> Settings tab has been reworded to make the functionality more clear.
Updated Migration logic so that if an object (like an Organization or a Term) has been flagged as "Do Not Migrate" within the system, any associated child entities (like a Section) will no longer be Migrated if a user then manually selects the child entity for Migration. Instead, that child entity will also be flagged as "Do Not Migrate" if and when a user attempts to Migrate it.

Updated Documentation:

Updated Known Limitations and Pre-Migration Checklist surrounding ESS content that has been published to an LMS and your Migration options.

Stereo Audio

As a result of a fix that was implemented in Service Pack 13 (ECHO-29109), audio is now being processed in Stereo. If your Rooms are currently configured for mono audio, Echoes created will have a single stereo audio stream (audio playback only in one ear). We recommend that any rooms currently configured to capture mono audio should be rewired to capture stereo audio.
