• BUGFIX: UI: when folders were enabled on certain widgets, and the IDB was saved (e.g., by clicking on the 'save' icon), but then not saved again when closing, the widget would show up in no-folders mode
• BUGFIX: UI: when switching to a folders-enabled chooser, the folders might fail to have focus
• BUGFIX: UI: with certain fonts, the 'registers' widget could truncate the register names/values by a few pixels, making it harder to read
• BUGFIX: UI: zooming in the navigation band, could lose locality
• BUGFIX: Using "Jump to local type..." in a Pseudocode view's context menu wouldn't expand the tree of types to the right place (assuming the "Local types" has been toggled to be using folders.)
• BUGFIX: debugger: single-stepping could be sluggish with multi-threaded apps, especially in the Mac debugger (see Debugger>Debugger options>Optimize single-stepping. it is enabled by default for Mac debugger).
• BUGFIX: decompiler: "create new struct type" could generate a new struct type with forbidden characters, like <
• BUGFIX: decompiler: arm64: some references to external symbols would not be resolved
• BUGFIX: decompiler: assignments to members of structurs later passed by reference could be optimized away
• BUGFIX: decompiler: automapping variables was too aggressive in some cases
• BUGFIX: decompiler: bit-manipulation instructions 16-bit registers were emulated incorrectly (shift count is only 4 bits for them)
• BUGFIX: decompiler: changing the type of a structure field would cause the loss of the __cppobj attribute
• BUGFIX: decompiler: decompile() would crash if asked to decompile an unexisting function (nullptr)
• BUGFIX: decompiler: decompiler could crash after using "extract func" if a pseudocode window with the deleted function info was present
• BUGFIX: decompiler: fixed a crash in the recognition of magic divisions
• BUGFIX: decompiler: fixed a crash on corrupted idbs
• BUGFIX: decompiler: fixed an endless loop (extremely rare)
• BUGFIX: decompiler: fixed interr 52194
• BUGFIX: decompiler: global xref cache could become stale after a user action that was changing only the line numbers (like adding a comment)
• BUGFIX: decompiler: in some cases 'split expression' had no effect
• BUGFIX: decompiler: in some cases action "Reset pointer type" was not working (had no effect)
• BUGFIX: decompiler: in some cases decompiler could generate a wrong post-increment/decrement operator
• BUGFIX: decompiler: in some cases the decompiler would add a suffix to the user-defined names (myvar->myvara)
• BUGFIX: decompiler: in some cases the user could not add variadic arguments to a function call
• BUGFIX: decompiler: jumping to the pseudocode from another window (for example, from the local types) would fail to activate the window in some cases
• BUGFIX: decompiler: ppc: fixed address arithmetics when subtracting addresses
• BUGFIX: decompiler: recognition of inlined memset() was too aggressive in some cases (a xor loop could be converted to memset)
• BUGFIX: decompiler: renaming a structure field would cause the loss of the __cppobj attribute
• BUGFIX: decompiler: shifted pointers with negative offsets were not always applicable
• BUGFIX: decompiler: some assignments could not be split
• BUGFIX: decompiler: some xrefs to enum members would be missed by Ctrl-Alt-X
• BUGFIX: decompiler: stale cached pseudocode was not refreshed in some cases
• BUGFIX: decompiler: the decompiler could crash when displaying the global xref list if the cache was stale
• BUGFIX: decompiler: trying to rename a variable as "@@x" would lead to a fatal error
• BUGFIX: decompiler: while(2){switch...} could be decompiled incorrectly in some cases
• BUGFIX: decompiler: wrmsr instruction could be decompiled wrongly (value of edx was unused)
• BUGFIX: decompiler: x87 fscale instruction was decompiled incorrectly
• BUGFIX: windbg: segment bitness could be determined incorrectly
