Issues Resolved in Native Client 10.1

This section describes issues resolved in VMware Tanzu GemFire version 10.1 and its patch releases, beginning with the most recent release.

Issues Resolved in Native Client 10.1.3

GEODE-8297, GEMNC-472: Increased default timeout value for authorization to accommodate networks with higher latency.

Issues Resolved in Native Client 10.1.2

GEODE-7930: Endpoint names are no longer truncated to 99 characters. The Native Client now supports endpoint names that meet the RFC 2181 standard of 255 characters for fully-qualified domain names. This solution also corrects a spurious “Failed to add endpoint” error that was issued when, in fact, no error had occurred.

Issues Resolved in Native Client 10.1.1

GEODE-8015, GEMNC-470: Added debugging symbols to the released libraries. The Native Client release for Windows now includes a .pdb symbol file. On Linux, the symbols are now embedded in the shared library (.so file).
