Hello ussdev. Take your time. Don't give us release dates. It causes a lot of pressure and it's the main source for bugs.
I suggest that you publish the test build in addition to the stable builds on the download page with a warning that it has bugs.
Make a list of known bugs in a text file and put it in the main folder of the test build. Publish a new test build each week or whatever frequency suits you. And tell us in the known bugs file if there are specific things you want us to test.
Once you have a stable release published, I suggest working on smaller updates and continuing with test builds in between.
