Where can I find release dates for new IBM Rational Lifecycle Integration Adapters (RLIA) versions?

Where can I find release dates for new IBM Rational Lifecycle Integration Adapters (RLIA) versions?

I'm asking because I cannot find this information in the public RLIA website, and Tasktop support nor RTC support does not have this information too.
More background:
End users are looking at Tasktop Sync adapter for JIRA/RTC
JIRA 7.6.3 is not supported in the current version of Tasktop Sync.
Tasktop Sync 4.13, coming out January 23 will support the JIRA version
The equivalent RLIA version number will be 1.2.0.5, but Tasktop support has no information about RLIA release dates
End users' JIRA upgrade is urgent and they may have a period of time when they would need to use an unsupported combination of JIRA/RLIA versions.
They need to know the release date, so that they can plan if they need to take large efforts to test the unsupported combinations (this testing is not required if the new RLIA is coming out before upgrade)
