- nim-gdb can be successfully launched as it finds and loads nim-gdb.py correctly under gdb.
- nimble package manager stores package information per user.
- compiler package can be found and used, as it may be required by other packages.
Update to 1.6.6
- standard library use consistent styles for variable names so it can be used in projects which force a consistent style with --styleCheck:usages option.
- ARC/ORC are now considerably faster at method dispatching, bringing its performance back on the level of the refc memory management.
