Just found out about this, so I'm re-posting this notice, slightly edited: http://www.inkscapeforum.com/viewtopic.php?f=21&t=32932#p100877
Development versions of Inkscape for Windows (currently for 0.92.x branch and for master branch (formerly called 'trunk') ) are now automatically created on every change to the code base. They can be found at
https://ci.appveyor.com/project/inkscape/inkscape/history
Click on the title of the build you want to test, i.e. a URL that goes like: https://ci.appveyor.com/project/inkscape/inkscape/build/master-606 or https://ci.appveyor.com/project/inkscape/inkscape/build/0.92.x-607
On the next page, below 'Job Name', select if you want the 32 or 64 bit version (Environment: MSYSTEM=MINGW32 or Environment: MSYSTEM=MINGW64).
On the next page, click on 'Artifacts' (at the right, right above the terminal-like box).
On the next page, download a 7z file. (If necessary, you may need to install the 7z decruncher, from http://www.7-zip.org/)
................... For Ubuntu, there's https://launchpad.net/~inkscape.dev/+archive/ubuntu/trunk (0.93 devel series) and https://launchpad.net/~inkscape.dev/+archive/ubuntu/stable-daily (0.92.x series)
