This release contains recompiled zlibwapi.dll, preflate_dll.dll, lzo2.dll (to remove Visual C++ 2010 requirement) and xdelta3_dll.dll simply because there are people who are using Windows XP in this day and age, shocking I know...

Thank you Razor12911 for your updated xtool and libraries...anyway, tested unpacking speed of your last three x64 zlibwapi.dll library compiles, multiple times (did not test x86 version at all)...

Unpacking speed of zlibwapi.dll 1.2.11/2020-07-18/535552 bytes is _always_ faster than any of your other, newer, 1.2.13 compiles (2022-12-31/544768 bytes and 2023-07-11/512000 bytes)
Newest XP compatible zlibwapi.dll is by far slowest during unpacking, probably because it does not use some of advanced CPU instructions available after XP. Anyway, I truly welcome XP support because I consider games that are playable on XP should be able to unpack on XP...but if making .dlls XP compatible comes with obligatory speed loss than maybe it is better to provide separate XP compiled libs, just my thoughts of course. Ideally, one compile should work on all OSes with max speeds but don't really sure if this is possible...

Following are examples of decompression speed of _same_ arc packed with xtool:zlib+srep:m3f+lolz ,all that is changed is zlibwapi.dll before unpacking (encoding speed is not primary important to me, arc is packed using one of mentioned zlibwapi.dll but this does not impact decompression speed, tested)
Tested on Windows 11, 20 threads CPU, xtool 0.7.4 used, -t100p in arc.ini

Using zlibwapi.dll 1.2.11/2020-07-18/535552 bytes:
Extracted 4 files, 2,649,948,418 => 4,683,666,810 bytes. Ratio 56.58%
Extraction time: cpu 0.97 sec/real 74.49 sec = 1%. Speed 62.87 mB/s
All OK

Using zlibwapi.dll 1.2.13/2022-12-31/544768 bytes:

Extraction time: cpu 1.59 sec/real 83.01 sec = 2%. Speed 56.42 mB/s
All OK

Don't really know what you did with 1.2.11/2020-07-18 compile because that was clearly the fastest zlibwapi.dll, at least for me. Yes, I know it is older 1.2.11 version and maybe missing some updated code but I never encountered any problems with it..
