Latest release

v0.11.3 beta (2008-02-01)
Changes:

• fixed: more stack unwinding problems

Previous releases

• fixed: access violation when unwinding the stack

v0.11.1 beta (2007-12-16)
Changes:

• fixed: skip symbol sections in codeview data if invalid lengths are found
• fixed: added several composite pointer types to codeview parser

v0.11 beta (2007-12-02)
Changes:

• debugging DLLs
• load executables without debugging info
• only intercept exceptions, don't handle them (continuing after an exception will invoke the program's exception handler)
• print last known source location in stacktrace (e.g. if exception is thrown from within a runtime library call)
• automatically switch to stackframe of last known source location on exception (configure behaviour with new jkf command)
• added command el to set max evaluation length for arrays

• da, dal and ps respect the currently selected frame
• use corrected CodeView types for char, wchar, dchar, bool in DMD 1.019/2.003
• changed: ddbg doesn't ignore int3 instructions explicitly executed by the debuggee any more
• fixed: demangle static local variables correctly (e.g. module.function.varname)
• fixed: breakpoints set on wrong line if degenerate debug info present or multiple modules share source lines
• fixed: absolute paths not accepted in bp command
• fixed: dal disassembles from current address (should be line start)
• fixed: "invalid UTF8 sequence" exception when printing non-UTF8 DLL names or exception messages

v0.10 beta (2007-06-24)
Changes:

• Support for multi-threading (note for frontend developers: Ddbg's breakpoint messages changed!)
• Post-mortem debugging using Minidumps
• New commands (see Documentation for details): ldll, lt, mi, st, onex, onterm, rmd, wmd

• Expression error messages with unmangled types
• Cleaned up help
• ddbg.exe packed with UPX

Changes:

• changed inconsistent versioning to major.minor[.patch-level] (after 0.0.6, followed by 0.1, this is the eighth minor version)
• single char, wchar, dchar characters printed as hexadecimal integer
• non-recursive mode for evaluation of nested data structures ("er" command switches modes)
• added typeof command "t" for Ddbg CLI, "whatis" for GDB CLI that prints the type of a Ddbg expression
• support register call (e.g. "call edx") in stepping (used in some foreach loops and lazy evaluation for example)
• try ".exe" if no file extension is given for debuggee on command line

• fixed: incorrect stepping behaviour in foreach loops with opApply that has source info

v0.1.1 beta (2007-04-11)
Changes:

• added memory validity check for expression evaluation (prevent crash when trying to interpret uninitialized symbols)

Changes:

• use new OEM codeview types for dynamic and associative arrays and delegates (requires DMD 1.011)
• stepping through foreach on structs, classes and AAs (those using opApply)

• convert debuggee's data to UTF8 if invalid

Note: the CLI mode selection has changed and with it the way Ddbg is called by Code::Blocks. See the documentation for details.
