Originally reported here: http://www.igniterealtime.org/forum/thread.jspa?threadID=25650 I was able to reproduce locally on Wildfire 3.2.3 Enterprise using spark_2_5_0.exe and spark_2_5_0_beta4.exe. When I log in to the server with Spark 2.5.0 beta 3 and the server is configured to deliver spark_2_5_0.exe there is no update notification. If I switch the active build to spark_2_5_0_beta4.exe then there is an update notification. Steps to reproduce: 1) Upload spark_2_5_0.exe and spark_2_5_0_beta4.exe 2) Select spark_2_5_0.exe as the active version in Enterprise 3) Log in using Spark 2.5.0 beta 3 4) Note that you receive an update notification 5) Switch the active version in Enterprise to spark_2_5_0_beta4.exe 6) Select "Help > Check for updates" in Spark 2.5.0 beta 3 7) There is no update
