Category changes with Unicode 6.3

["Martin J. Dürst"]

Excuse me if this has been checked and/or discussed already, but I just 
downloaded the Unicode 6.3 version (officially published a few days ago) 
of http://www.unicode.org/Public/UCD/latest/ucd/UnicodeData.txt and 
found several changes in character classification:

OLD
180E;MONGOLIAN VOWEL SEPARATOR;Zs;0;WS;;;;;N;;;;;
NEW
180E;MONGOLIAN VOWEL SEPARATOR;Cf;0;BN;;;;;N;;;;;

OLD
1A1B;BUGINESE VOWEL SIGN AE;Mc;0;L;;;;;N;;;;;
NEW
1A1B;BUGINESE VOWEL SIGN AE;Mn;0;NSM;;;;;N;;;;;

OLD
2308;LEFT CEILING;Sm;0;ON;;;;;Y;;;;;
2309;RIGHT CEILING;Sm;0;ON;;;;;Y;;;;;
230A;LEFT FLOOR;Sm;0;ON;;;;;Y;;;;;
230B;RIGHT FLOOR;Sm;0;ON;;;;;Y;;;;;
NEW
2308;LEFT CEILING;Ps;0;ON;;;;;Y;;;;;
2309;RIGHT CEILING;Pe;0;ON;;;;;Y;;;;;
230A;LEFT FLOOR;Ps;0;ON;;;;;Y;;;;;
230B;RIGHT FLOOR;Pe;0;ON;;;;;Y;;;;;

Can somebody check whether and how they affect IDNA 2008 and/or precis?

Again, if that has already been done, sorry for the noise.

Regards,   Martin.
