I think the meaning of
"---
Since 5.2.1
Mersenne Twister in PHP now use new algorythm of reinitializing, developed by Richard Wagner
Same seeds not produce same chains of values.
---"
Is that the sequence you get out of version 5.2.1 or greater is different than the sequence you got
from the versions prior to that for a given seed, i.e. something changed in the pseudo-random number
generator to change the sequences.
