You can update outdated packages like so:
brew install `brew outdated` (or brew outdated | xargs brew install (or brew
upgrade))
1 Homebrew will attempt to automatically derive the formula name and version, if
it fails, you’ll have to make your own template. I suggest copying wget’s.
2 This is done automatically when you install formula. It is useful for DIY
installation, or in cases where you want to swap out different versions of the
same package that you have installed at the same time.
3 This is generally not needed. However, it can be useful if you are doing DIY
installations.
4 To delete only a specific out of date version, just go to the folder in the
Cellar and “rm -rf” it, or drag it to the trash in Finder.
