• Hipchat notifier. You can now send stale PRs to a hipchat room.

Housekeeping:

1.0.0

This release adds the following features:

• Labels for each PR are now displayed in the email notification.
• Ability to include/exclude PRs based on labels.
• Added console notifier in order to get a preview of the output prior to sending the email/github labels.

v0.3.0

The stale PR title is now escaped in email notifications.

Minor change to expose PR updated time.

v0.2.1

Bumping version to v0.2.1.

Label fixes

Fixes a bug where the label option of drill-sergeant would override all labels and replace with Stale. It will now always append.

Also removes unnecessary files from the NPM package. The runtime environment does not need tests and grunt tasks.

• Append labels #8
• .npmignore #9
