If you are using it and notice problems, it's best to log an issue or let us know at greasemonkey-dev (and be clear that it's with this version).
This release was hurried, to resolve a few serious bugs introduced in 0.9.14. A few other bugs were also fixed.
- Editing an installed script to change any remote dependency (@icon, @require, @resource) could cause one or many scripts to be deleted. (#1466, #1502)
- Toggling the enabled state of a script via the main (Tools > Greasemonkey) menu failed on Mac. (#1496)
- Installing a script from local disk failed in 0.9.14. (#1501)
