changes

-

dartfmt
-

Better line splitting in a variety of cases.
-

Other optimizations and bug fixes.
-

Pub
-

*Breaking:* Pub now eagerly emits an error when a pubspec's "name"
field is not a valid Dart identifier. Since packages with non-identifier
names were never allowed to be published, and some of them already caused
crashes when being written to a .packages file, this is unlikely to
break many people in practice.
-

*Breaking:* Support for barback versions prior to 0.15.0 (released
July 2014) has been dropped. Pub will no longer install these older barback
versions.
-

pub serve now GZIPs the assets it serves to make load times more
similar to real-world use-cases.
-

pub deps now supports a --no-dev flag, which causes it to emit the
dependency tree as it would be if nodev_dependencies were in use.
This makes it easier to see your package's dependency footprint as your
users will experience it.
-

pub global run now detects when a global executable's SDK constraint
is no longer met and errors out, rather than trying to run the executable
anyway.
-

Pub commands that check whether the lockfile is up-to-date (pub run, pub
deps, pub serve, and pub build) now do additional verification. They
ensure that any path dependencies' pubspecs haven't been changed, and they
ensure that the current SDK version is compatible with all dependencies.
-

Fixed a crashing bug when using pub global run on a global script
that didn't exist.
-

Fixed a crashing bug when a pubspec contains a dependency without a
source declared.
