video tutorial: making new SqueakMap Package Releases
by Chris Muller 25 Apr '18

25 Apr '18

Since we have a new release coming out, I decided to make a video that shows me updating one of my SqueakMap package releases, in case it's a useful context for others to update theirs and have a great release with lots of software loadable out of the box. https://www.youtube.com/watch?v=rbfIGOuN_fI I did no preparation, and no subsequent editing whatsoever, I just did it, but filmed it while I did and spoke my thoughts out loud... I hope you find it useful. - Chris
