Keep your Atom packages up to date.
$ apm install auto-update-packages
Just sit tight. :)
auto-update-packages automatically checks for package updates every 6 hours by default. If any updates are available, it installs them and notifies you via OS X Notification Center.
Note that after the update you need to Reload (⌃⌥⌘L) to apply the updates to the opened Atom window.
If you're impatient, run Packages menu > Auto Update Packages > Update Now.
You can configure auto-update-packages
in the Settings view (Preferences... in Atom menu)
~/.atom/config.cson (Open Your Config in Atom menu):
Specify an auto-update interval. If you specify a value less than 15, it will be handled as 15 internally.
Note that auto-update-packages does not adhere the value strictly. It has some margin around 5%.
