OllyDbg 2.01 Beta 2 Released! (x86 Debugger For Microsoft Windows)

The author, Oleh Yuschuk (also known as Olly), of widely used assembler level debugger 'OllyDbg' has released the Beta 2 version of OllyDbg 2.01. As you all know OllyDbg itself is hardly changed, only minor improvements (like correct reaction on MOV SS,anything; PUSHF or disassembling of JE vs. JZ  etc. depending on the preceding comparison). More important, the developer have removed the nasty crashes that happened on some computers while invoking menu, or pressing ALT, or on similar harmless actions. 

Last year August got the Alpha 4 of OllyDbg 2.01 since then we have not seen any upgrades or improvements, so after one year this release includes some of major upgrades and fixes several bugs. Plugin interface is slightly extended. Plugin API includes more than 500 functions, structures and variables. Of these, I have described less than 100, so you will frequently encounter 404 while browsing the help data. But all APIs used by Bookmarks plugin are fully documented.

I would also like to describe briefly for those who are not familiar with debugger- OllyDbg is an x86 debugger that emphasizes binary code analysis, which is useful when source code is not available. It traces registers, recognizes procedures, API calls, switches, tables, constants and strings, as well as locates routines from object files and libraries. In many cases reverse engineers preferred OllyDbg, even this tool is widely used by underground communities for making crack of popular software & games.
