Upgrading from ionic 13 to 14

Hi, I’ve built an app using beta v.13 and I’m looking to upgrade to the latest beta, I’m wondering what the pro’s and con’s are (I’m running on Windows if that makes any difference)

Upgrade to the newest rc0!

Brings improved collection-repeat, spinners and much more.

Well one thing is that beta 14 is newer and has bugfixes against beta 13.
Also beta 14 is closer to the final first release. After beta14 only Release Candidates will follow, which should be easier to upgrade to from beta 14.

Also there are some performance and caching enhancements between beta 13 and 14, see http://ionicframework.com/blog/the-final-beta/
