ActiveGate release notes for version 1.187, published on January 31, 2020, highlight key updates and support changes for Dynatrace users. The notes emphasize the importance of updating ActiveGates older than version 1.154, as Dynatrace version 1.188 will no longer support these older versions due to the introduction of 64-bit host IDs. Users are advised not to cancel Windows ActiveGate updates, as doing so can inadvertently remove the current installation; a workaround is provided for those who encounter this issue. The release also includes the resolution of three issues, including fixing the return from "failover" mode and ensuring proper collection of CloudWatch metrics for DocumentDB AWS instances.
