Sonatype Nexus 2.8.1 Release Notes

These notes are a compilation of new features and significant bug fixes for Sonatype Nexus 2.8.1.

See the complete release notes for all resolved issues.

New and Noteworthy

Temporary Directory Handled Consistently

It was possible that the temporary directory used by Nexus was indeterminate for some operations. The preferred default temporary directory was ${NEXUS_WORK}/tmp, but since that value cannot be reliably set by default before boot, Nexus now defaults the temporary directory used as ${NEXUS_HOME}/tmp. This may impact the disk space requirements for some installations. See the article discussing the temporary directory for more information. NEXUS-6595

Smart Proxy Performance Improvements

Working closely with our customers, we have identified some Smart Proxy performance issues in certain circumstances. Smart Proxy users should consider upgrading to benefit from these changes. NEXUS-6570,NEXUS-6600

Notable: Turn on strict URI matching in restlet

Nexus restlet now uses sctrict URI matching as the default.  This may impact the functionality of some third party plugins.  If you are using plugins not supplied by Sonatype you should test these against 2.8.1 before upgrading, it is possible (although unlikely) that REST endpoints in these plugins may not work correctly in 2.8.1.   NEXUS-6630
