A pre-GopherCon release, the biggest change being breaking changes to package sd. We now expose the raw instance strings from each underlying service discovery system, so that consumers can do things with them other than construct endpoints. For background, see issues #475, #403, and #209, and for the (extensive) discussion, see PR #492.
Besides that, we just have a solid set of improvements and enhancements. See below for the full changelog. Huge thanks to Yuri Shkuro @yurishkuro for his tireless work on package sd, including dealing with my mercurial demands and frustratingly irregular schedule. And huge thanks to the 17 individual contributors who've contributed to this release! 🏌️♀️
