[panker1992]

Changes - WIP 5, 21/10/2025 (Complete Overhault)

At this point, i decided to make this tool, from scratch, everything has been created from the beginning
so i fixed countless bugs ,added a plethora of new Features.

New: Filters, in Low API, when the archive is taking the data in, aka source gathering , with tolerance , aka filter configuration
New: Span, Spanning can be activated but with some limitations, spanned archives cant contain updated streams inside for now.
New: CLS-host, with partial compatibility from Bulat's Freearc, NOTE: not all filters work and i haven't tested every single one that exists.
New: 4x4, works similarly to FA with the ability to use internal and external codecs, but not CLS-Filters for now. Note: creates temps for external. but its very fast and efficient

All around fixes and optimizations:
1) Fixed: Stability, optimized several functions which in decompression in particular has to read and reread the archive several times before unpacking.
2) Created Unarc.DLL.
3) Reduced size of the executable with 1 mb.
4) Removed depedencies from the code to work barebone
5) LZAV,Lizard, FastLzma2 have been removed from the DLL and are now Native to the executable.
6) ZSTD has been updated to 1.5.7
7) XXhash has been updated to 8.3
8) LZ4 has been updated to 1.9.4
9) Fixed internal zlib which was creating depedencies and errors , it was seeking
10) fixed lzma which had bugs, was creating buffers and it was bufferign the entire stream to ram, removed lzma2, you can use lzma2 via 4x4:b512:t4:mlzma:d256:l9.

ArchiveManager is now an advanced way to unpack your Data easily and view them in real time. provided a starting point in the future to come.

Generic IO fixes has been made as well.


There is a known issue, liblzma.dll in 32 bit doesn't work and it will give a runtime error no matter what. if this continues the 32 bit's functionality will be severely decrease
