What's New in Tanzu GemFire 9.15

GemFire/Geode Realignment
GemFire 9.15 is based on Geode 1.15. The previous release of GemFire, v9.10, was based on Geode 1.12. With the GemFire 9.15 release, GemFire now incorporates all of the improvements introduced in Geode versions 1.13, 1.14, and 1.15.
Connection Reauthorization
GemFire security has been improved by implemented authentication expiration. Authentication expiry makes it possible for cluster administrators to limit the life span of client and peer connections within the cluster. See Implementing Authentication Expiry for details.
Default GemFire property value changed
The conserve-sockets GemFire property's default value has been changed from true to false.
GEODE-9982, GEM-3509: protocol alignment/client-server handshake fix
GemFire Native Client applications must be upgraded to at least version 10.2.7 before upgrading the GemFire server to v9.15.
Experimental Redis Adapter removed
The experimental Redis Adapter was removed from the Tanzu GemFire release. It will be replaced by a stand-alone add-on.
TLSv1.1 deprecated
TLS 1.0 and 1.1 have been deprecated by the Internet Engineering Task Force (IETF) as of March 25,2021. GemFire utilizes the Java Runtime for TLS, so ensure your Java RunTime has been updated to ensure TLS 1.0 and 1.1 have been mitigated.
