Tools for Repacking

[artag]

i don't know if this is the right place to ask, sorry if my english is bad:

wich is the safest and stable cls for precomp right now? (with stdio support) and which
precomp version should i use?

which is the safest cls for srep? (or maybe should i use srep without it). what version is the most stable until today ? 2.2, 3.93, 4.90?


can i remake my old repacks with xtool and forget about pzlib (for zlib streams of course) or pzlib should be used for old games or something like that?

i used lolz 21a7, is there a new updated version?

inno setup 6xxx is stable with isdone dll?

many thanks!
