v0.1.3 was recently marked stable and it is recommended you upgrade to this version. Each version has seen a bunch of improvements and issues fixed, so it's a good idea to upgrade. Currently, the focus is on dcrd, and a ton of work is going into syncing it to the upstream project, which means it'll pull in an incredible amount of fixes and improvements as well. If you've experienced issues with wallet, restore from seed when you upgrade, and remember to keep a backup.
