Frank Quinn <>

Hi Folks,

We are pleased to announce the first release candidate for openMAMA 6.2.1 is now available:

This is a bugfix release to address a few main issues:
  • Fixed issue with extended datetime representation on 32-bit systems (Windows and Linux)
  • Fixed issue with multiple subscribers for the same topic on qpid
  • Fixed crash in conflated order book processing
For a complete list of all 9 issues included in this release, please see here:

Thank you all in advance for your help in testing - if you spot any issues, please follow our guidelines for raising an issue, or even better, follow our guidelines for raising a patch.

As this release is fairly small bugfix release, we're not expecting a large volume of bugs to fall out, so I will be acting on a reasonably brief test window of 1 week commencing today. If no issues have been found, we can aim to release on 29th May. If critical issues are found, we will continue to go through weekly release candidates until have a stable release ready.
