ISApexEx - Unified API for 7z / FreeArc / RAR Extraction and Xdelta3 Patching

Ya, I agree. In the current scenario (repacking), FreeArc plays a huge role, so the entire backbone of ISApexEx effectively depends on it.
The lack of support for `cls-srep.dll` , `cls-lolz.dll`, etc. also leaves a huge gap. Without support for them, ISApexEx becomes more of a toy tool than a top-tier tool.

Because of that, the transition to Inno Setup 7 x64 won't be particularly easy or smooth from this side, especially since many of the plugins we commonly use, such as `botva2.dll`, are still x86, and some of them haven't received updates in *years*.

So, I do plan to release an x64 build of ISApexEx, but for now, I'd like to buy some time before releasing it. In the meantime, we can try compiling the entire FreeArc project as an x64 build. Hopefully, we'll also find a solid and practical way to handle the existing x86 CLS plugins whose development has already stopped, so they can still be supported in an x64 host.

It's not a big deal, you can convert Botva2.dll to x64 very quickly. I'm sure of it

ISApexEx Update

━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ ━━━━━━━━━━━━

▌ v0.1 Beta 2 (Build 6A3DC100)

✦ Added

• New engine: HDiffPatch v5.0.0 — applies .hdiff binary patches (old + diff → new), single-file and batch directory modes. Native DLL: hpatchz_wrapper.dll (apply side only). ArchiveType APEX_ARC_HDIFF = 4. Lazy-loaded; not a load-time dependency of ISApexEx.dll.
• New exports — ISApexExAddHDiffPatch, ISApexExAddHDiffPatchDir (default batch pattern '*.hdiff').
• .hdiff extension auto-detected and routed to the HDiffPatch engine; mixes with .7z / .arc / .rar / .xd3 in one session with unified progress (0–1000).
• New example installer — bin\ISApexEx_Example_HDiff.iss.
• ERROR_HDIFF_* language strings in English.ini and Russian.ini.
• Thanks, @Cesar82, for the HDiffPatch suggestion.

✦ Changed — BREAKING
xdelta patch exports renamed (signatures unchanged):

╭──────────────────────────┬──────────────────────────────╮
│ Old name (removed)       │ New name                     │
├──────────────────────────┼──────────────────────────────┤
│ ISApexExAddPatch         │ ISApexExAddDeltaPatch        │
│ ISApexExAddPatchDir      │ ISApexExAddDeltaPatchDir     │
╰──────────────────────────┴──────────────────────────────╯

Update any [Code] script that calls the old names. The generic "Patch" names are removed entirely.

✦ Changed

• Batch (...Dir) patching is now recursive by default for BOTH engines — scans subfolders too (switched to the leaner wfs_FindFilesForHashEx scanner; faster, lower memory, same relative-path results).
• Version v0.1 Beta → v0.1 Beta 2; build 6A20C000 → 6A3DC100 (shown in init log, DLL version info, and dialog titles).
• ISApexEx.iss header, example scripts (.iss), and the forum description updated for the new engine and renamed exports.
• Inno Setup example scripts updated to work with both Inno Setup v6.x and v5.x.

✦ Fixed

• Single-file patching now force-overwrites the output even when it is read-only/locked — the read-only attribute is cleared and the stale file removed before patching, in BOTH the Delta and HDiff engines.

✦ Upgrade Notes

• Rename xdelta calls to the ...Delta... names (see the BREAKING table above).
• To apply .hdiff patches, ship hpatchz_wrapper.dll next to the other engine DLLs and call ISApexExAddHDiffPatch / ...Dir.
• ...Dir patching is now recursive — confirm no stray patches sit in subfolders you did not intend to process.
