newbie: package removed from testing, what is my next step ?

[Roelof Berg]

Hello,

I'm new to Debian and wonder, what the e-mail below might mean. I 
assume, that something's wrong with my package and therefore it is not 
included in Debian testing any longer, right ? And do I understand 
correctly that there is a task for me (package maintainer) to "finish 
the opencv transition" to make it available in Debian testing again ? If 
yes, I wonder what could be meant by "finish opencv transition". Is 
there a way to find out who wrote this line, then I could ask her/him.

I also wonder why there V 1.4.0-1 is listed, while in SID already V 
1.4.0-2 is uploaded. Must I maybe tell someone (like a sponsor), that 
the version in SID could also be added to testing ?

FYI: The status of the limereg source package
in Debian's testing distribution has changed.

   Previous version: 1.4.0-1
   Current version:  (not in testing)
   Hint:<https://release.debian.org/britney/hints/pochu>
     #20150926; done 20150927
     # finish the opencv transition

Thanks, I appreciate every answer and I'm happy to put work into this, and maybe into more packages in the future, after I learned all about package maintenance,
Roelof
