Version 5.3.0.4 - 31 December 2012 - The class browser now always differentiates between private and public members. - Fixed the "String not found" messagebox appearing behind the find form. - Greatly enhanced the autosave feature. It can now save timestamps and filter by project too. - Reduced flicker when closing editors. - Added tcc files to the highlighting list. - Fixed some rare folding bugs, and improved their performance a bit. - When using Goto line or any other function that changes the current line, folds will be uncollapsed to make the destination line visible now. - Evaluate and GDB input edit controls now do not cut off the selection when autocompleting. - Double clicking on a find result now correctly shows the find result at the top line (instead of one line above that). - Errors now have more priority than warnings (which have more priority than other messages) when changing focus to a compilation issue. - Swap Header/Source now opens complementary files in a tab right next to the current file. - Translations in Goto function will now always fit. - Compile Log now shows a final warning count too. - Fixed the function tooltip highlighting wrong arguments when putting a space before (. - When renaming project files, you'll be asked before any overwriting takes place. - Removed WM_CLOSE handling from the default WinMain snippet. DefWindowProc will handle this. - The function parameter tooltip now shows class scope info too. - More bug fixes and feature additions here and there. Version 5.3.0.3 - 11 November 2012 - Fixed really long watch variables being cut off sometimes. - Fixed the goto line form playing a beep when hitting enter. - Fixed an infinite loop bug when parsing inheritance. - The tip of the day window is now focused on startup, making hiding it using the keyboard easier. - The C++ parser now understands what to do with <cxxx> includes: parse <xxx.h> instead. - Simple replacing ("Replace") now correctly replaces matches by the replacement text instead of nothing. - Dev-C++ will now show a nice warning dialog about incompatible caches instead of throwing exceptions. - Startup time has been improved by as much as 20%. - Code completion now properly shows all global functions again. - Project closing is done instantly now when using 'Scan global includes'. - The function tooltip now also shows constructors and destructors. - Added a button to Compiler Options that will autodetect compilers. - Updated chinese (TW) translations. - CPU window now opens up 50% faster after a signal is received during debugging. - More bug fixes here and there. Version 5.3.0.2 - 24 Oktober 2012 - Fixed error line focus dissapearing when moving focus on the same line. - The window caption now shows more information, like the debugging/compiling/executing status. - Fixed compilation failing when the compilation progress window is hidden. - CPU Window now updates faster. - One can now properly use Replace in Files to replace files not yet opened. - Upgraded the variable finder. - Added a find count to the bottom of the find output list. - Debug evaluation now hints the user when it contains old potentially invalid data. - When trying to debug, Dev-C++ now suggests to compile, instead of showing an error that the source isn't compiled. - Project options are now properly applied when not changing tabs in Project Options >> Compiler. - New projects now properly use the global compiler set by default. - Added two more themes. Credits go to Andrei Luca. - Improved parsing speed somewhat. - Improved startup time. - Reduced the amount of clicks needed to change compiler options. - Fixed numerous debugger bugs, most are related to watch variables. - When a signal is received by gdb, Dev-C++ now suggests to open up CPU window. - Fixed a lot more bugs. - Fixed a bug in the code completion form that prevented the source from being compiled on fresh Delphi IDEs. - Fixed an error in the relative path solver, making Dev-C++ fully portable again. Version 5.3.0.1 - 2 Oktober 2012 - Searching is now done forward instead of backward by default - Search history is remembered while Dev-C++ is opened instead of while the find window is opened. - Fixed a bug in CPU window that causes Dev-C++ to consume an infinite amount of memory. - Dev-C++ now checks if there are any compilers installed before attempting to use them, avoiding crashes. - One can now view project information like total lines in the File Properties window. - Rewritten the code that reads profiling output, drastically reducing flicker. - One can now use copy in the file properties form. Version 5.3.0.0 - 30 September 2012 - Completely rewritten the debugger interface. - Completely rewritten the find/replace form. - Improved some internal (compiler) data structures, reducing memory usage and potentially improving stability by simplifying code. - Improved startup speed, splashscreen is hidden (not even loaded) when startup times are estimated to be very low. - Fixed nearly all the memory leaks. - Indent guides are now painted faster, reducing flicker. - Code completion is now more clear and pops up faster. - Color selectors in Editor Options now properly set their own defaults, not those of other controls. - Automatic symbol completion and indentation is much faster now. - Added OpenMP libraries and tools to TDM-GCC x64. - Code folding is updated much faster now. - The code parser now understands multiple definitions after the } symbol of structs. - Much more performance enhancements in the typing/editing department. - Dev-C++ now autodetects compiler versions (using gcc -v) automatically on first startup, instead of assuming versions it shipped with. - One can now use Cut/Copy/Paste/... in the find form, incremental search form, CPU form and debug interfaces. - Compilers can now be downloaded separately from the SourceForge repository. They will be autodetected at first launch when put next to devcpp.exe. - Updated Japanese, Chinese, English and Portuguese translations. - Fixed loads of bugs. Version 5.2.0.3 - 25 Juni 2012 - Fixed the function argument tip not selecting the function with the right number of arguments first. - Fixed that tip showing in various wrong places. - Added x86 GDB executables to TDM-GCC x64. - Tooltip balloons are now only triggered by words wi
