Some feedback on the release notes:
The using statement now means something completely different. You can use the new experimental this pragma to achieve a similar effect to what the old using statement tried to achieve.
There's no explanation of what the new using statement does. (Or what the old one did, either!)
The project directory is not added to the search path automatically anymore. Add this line to your project's config to get back the old behaviour: --path:"$projectdir". (Do not replace $projectdir by the project's directory!
If you're not supposed to replace $projectdir with the project's directory, then why it is called $projectdir? And what is a project directory anyway -- can you link to some documentation about the build process from here?
A generic "sink operator" written as &= has been added to the system and the net modules.
What does a generic sink operator do? If it had to be put in quotation marks, it probably deserves a longer explanation.
Overall, the notes read like they are mainly written for "insiders" -- as a casual reader, it is hard to understand what many of these changes mean. Links to further documentation would help.
This isn't meant to detract from the good work that the Nim team has done. If attracting new users is a goal, then polishing these notes
