v1.1.10 worked on 1.7.15, however i do not support old versions because they may contain unfixed bugs, and well i just can't test my work on every singly development version of anope so i chose to only support the latest dev version released.
Administrators should always update their software when an update is available anyways, certainly if that software is still a development release rather then module writers having to keep everything backwards compatible with development releases... if it were stable releases, there d be a point in keeping the modules backwards compatible within a branch, but i don't see any point in keeping it compatible with older development releases...
edit: a copy of 1.1.10 can be found
here, however know that it s unsupported and provided "as is"...
