iSymphony 3.5.9.8 Change Log

Last modified by Arthur Heffern on 2021/09/09 20:56

The following is a list of changes made between iSymphony 3.5.4 and iSymphony 3.5.9.8. This release should greatly improve memory utilization and resolves several memory leaks which users in high-volume environments  where customers reported the need to restart the iSymphony Server periodically. Please report any anomalies at http://support.getisymphony.com 


Warning

If you are not upgrading from iSymphony 3.5.4, be sure to check the change log and upgrade notes for previous versions as well.


Warning

IMPORTANT ERRATA: This version contains upgraded websocket push libraries (moving away from jquery push methods to plain javascript push). The side effect of this is that end users may get a "unable to load push" message when upgrading from any previous version(s) in a BIG RED BANNER at the top of the page when opening the client or administrator web interfaces after upgrading to this version.  If a user obtains this message, they should clear their browser cache or reload the page bypassing and refreshing the local cache (CTRL+F5 or Shift+Click Reload Button) or equivalent in the end-user's browser.

Future upgrades will not require this step as HTTP headers should now disable caching and the proper version should always be downloaded.

Improvements

  • Improved reliability and performance of HTTP push, switched to pure javascript AJAX push libraries for client DOM modifications.
  • Added HTTP push strategies. iSymphony will now use websockets in most browsers and falls back to long polling where websockets.
  • Added code resolving two Security vulnerabilities reported by 1st & 3rd party vulnerability scans.

Resolved Bugs

  • Resolved an issue where iSymphony cannot transfer calls that are ringing

  • Resolved several memory and performance issues which were reported on high-volume systems
    • Resolved memory leak in in-memory data store 
    • Resolved an issue where HTTP Push caused memory leak under certain circumstances.  
    • Upgraded components of a third party User Interface library resolving several memory leaks in the User Interface 
    • Resolved issue with client side (browser) memory leaks on AccountPopupButton instantiations due to server holding reference in List View. Large List views benefit greatly.
  • Resolved issue where leftover ASTDB values were causing invalid parsing of presence state when invalid entries existed in ASTDB during a "presencestate list" command and the extension entries did not exist within cxpanel model. This should resolve invalid presence state representations.

  • Fixed an issue where "remember me" wasn't working right in some instances.

  • Fixed an issue where "box width" in users box view wasn't saved after setting and clicking "Ok"

  • Added cache and pragma HTTP headers to resolve future issues with cached JS dependencies
