Beta and release candidates
Point releases (X.YY.Z), beta (-betaX) and release candidate (-rcX) versions of 8sms are interim versions for testing and development and may be unstable or have bugs. Use them at your own risk, and only if directed or you know what you are doing.
Generally, it is possible to upgrade or downgrade between a beta/RC version and the Google Play production version of the previous release. For example, between versions 1.30 and 1.31-rcX of 8sms.
Otherwise, changing between other versions of 8sms requires an uninstall and new install (and losing all your 8sms settings).
