Today I uploaded a bug fix release for the Qwt 6.1 branch.

Qwt 6.1.1 is a collection of all bug fixes, that could be added without breaking binary compatibility with Qwt 6.1.0. A summary of the changes is included in the tarball, or can be found here: IMO none of the fixes is about a killer bug, but as it is more than a year ago since 6.1.0 had been released, the number of fixes makes it interesting.

6.1.0 -> 6.1.1 is supposed to be a low-risk update, as all active development is happening in other branches
