For v2.12.6 tag

I created branch based on v2.12.5 tag with my three commits.  Then I try to do pull request but I can only link it to the branch (master is closest to v2.12.5 tag than other branches). And because of this pull request contains extra commits. 

Please use the following commits for merge into v2.12.6 tag:
Merge commit 'Added support for PropertyIsNull filter.'	d51865c6a293795e91e9402b52e868f1844aff01
Removed duplicate line that gets the filter value	a76acc57bad9853aa3b6b00b43463ff878da141b
Merge commit ' Updated IS_NULL filter to check for strict null.'	18d2379de388efb70d9e59e8837face3652d1a51

If you know any other way how I can create pull request more comfortable to merge – please let me know.
