iRODS, RENCI Announce the Release of iRODS 4.2.8

May 26, 2020

May 26, 2020 — The iRODS Consortium and RENCI are pleased to announce iRODS 4.2.8.

This release includes many enhancements to iRODS internals and the published C API, a few new C++17-enabled libraries and iCommands (istream and iunreg), and additional flow control within the rule engine plugin framework (REPF). Notable bugfixes include multiple edge cases around file names, better upgrade support from 4.1.x, and a performance improvement for rebalance. Two microservices and two flag usages have been marked as deprecated.

This release consists of 127 commits from 8 contributors and closed 122 issues.

The latest binary packages for CentOS7, Ubuntu16, and Ubuntu18 are available at https://packages.irods.org/.
