07.04.2021 Version 3.1.5 Added mapping "matchmaking_ds" library to "matchmaking_ds_srv" for Linux/Mac.
16.01.2022 Version 3.1.6:
[ASM_Instruction.inc] Added SizeOfCode, SizeOfProc - to calculate the length of opcode instruction / procedure (thanks to Ms-Rem & The Trick).
[ASM_Instruction.inc] Added IsRelativeCmd - to check whether JMP is relative.
#define PTR & Pointer are deprecated (to prevent confusion with C-Pointers). Use ADDR instead.
#define nullptr is deprecated. Use Address_Null instead.
Added define: ADDR - to view as Address.
Added defines: LA_8, LA_16, LA_24, LA_32 - shortcuts to load 1-4 byte size data from address.
19.01.2022 Version 3.1.7: MemSearcher: Added "IsValidPointer", better read access check.
18.03.2022 Version 3.1.8: Fixed "engine" library mapping.
08.07.2022 Version 3.1.9: Fixed warnings on SM 1.11. VirtualQuery optimizations (Windows).
06.11.2022 Version 3.1.10: Fixed "array out of bounds" in FindModuleString.
01.02.2023 Version 3.1.11: Added "test x,x" (0x85) assembler instruction.
