The Unicode Character Encoding Stability Policies ensure that developers know what they can depend on between successive releases of the Unicode Standard.

Recent changes to these policies include new guarantees:

    Property aliases will not be reused later for different properties.
    Property value aliases will not be reused later for different property values.
    Characters with the General_Category of Number are guaranteed to have a corresponding Numeric_Type value.

Additionally, the wording for two earlier guarantees about General_Category and Bidi_Class have been clarified: 

    No new General_Category property values will ever be added.
    New Bidi_Class property values can only be added for a tightly constrained class of new character additions.

For the exact wording of these new and updated guarantees, see Unicode Character Encoding Stability Policies. http://www.unicode.org/policies/stability_policy.html
