issues with changelog
~~- [x] new `--nim` option not listed in nimble -h~~ (EDIT: was looking at wrong version of nimble)

- [ ] https://github.com/nim-lang/nimble/blob/master/changelog.markdown#0120 says:
`Nimble will use it to store all package dependencies instead of ~/.nimble/bin`
=> isn't that ~/.nimble or ~/.nimble/pkgs ?

- [ ] `The default nimble test task also allows passing compiler flags but given run flags are not really applicable for multiple test binaries, it allows specifying compile flags before or after the test task`
  this is an inconsistency that should be reverted
