DQ2 Clients Testing Release 0.1.37

Item posted by Angelos Molfetas <angelos> on 2011-11-02 19:03.

Dear members of the ATLAS collaboration,

On behalf of the DQ2 team I am announcing the release of a new DQ2 Clients stable release, 0.1.37 "Taipei". This release has a new registration API for Panda and new retrial capabilities for dq2-get and dq2-put. The dq2-clientapi and dq2-clientapi-cli packages have been merged which produce a unified rpm.

Changelog for 0.1.37
