The Service Pack 1 of IDA 7.6 is primarily a bug fixes release that provides fixes for a few errors that might affect many users.
Complete changelist:
Installer:- IDA Installers for Apple Silicon (arm64) don't require Rosetta2 anymore and refuse to install on Intel Macs
- Verify correctness of function boundary metadata before using it
Bugfixes
- UI: QTreeWidget elements created from PyQt could fail to show any content
- Decompiler: in some cases IDA crashed on right-click in the pseudocode window
- UI: the string list cache was not restored in ida64
- DOS: when rebasing a DOS executable using full rebase (MSF_NETNODES), segment register change points were not properly updated to the new segment bases
- IDAPython: IDA could crash if ida_kernwin.twinpos_t.place was called for an invalid selection
- Decompiler: 'remove return value' command could spoil the __userpurge calling convention
- UI: In the "Structures" widget, 'Create before current structure' option wouldn't be honored anymore
- ARM: some CSNEG instructions were incorrectly simplified to CINV or CSETM instead of CNEG
- DWARF: When processing global variables, the DWARF plugin could erroneously delete items it shouldn't
- UI: IDA could crash instead of showing a proper error when it detected too many copies running on the local network
- IOS debugger could interr when querying the list of loaded dylibs
- UI: IDA could crash when using full screen mode (F11) without a loaded database
- UI: pressing Tab from the decompiler, to switch to a freshly-deleted disassembly view, could crash IDA
- UI: IDA could crash when opening the shortcuts editor on macOS when some window-managing programs were running
- UI: editing floating-point values in the hex view could fail
- IDAPython: ida_graph.abstract_graph_t.get_edge() could crash IDA
- UI: change accelerator for the "Optimize single stepping" option ('O' was already taken)
- Kernel: some event_listener_t hooks would not be unregistered on plugin unload which could lead to a crash later on
- Decompiler: fixed interr 50464
- Decompiler: fixed interr 50194
- Decompiler: fixed interr 52379
- Decompiler: fixed interr 50873
- Decompiler: fixed interr 52369
- Decompiler: fixed interr 50659
- An explicitly specified calling convention of a virtual function would be ignored when the compiler was set to Visual Studio
- IDA could hang on startup when running under Windows 10 Subsystem for Linux (WSL)
- Decompiler: IDA 7.6 could crash when using 7.5 decompilers
- UI: revert to the behavior of "create struct from data" to that of IDA 7.5 (use mangled names for struct members)
- IDA raised interr 1827 for fixed (i.e. having PLUGIN_FIX flag) plugins with postponed init
- Golang: handle go1.16 filenames and linenumbers metadata
- Source-level debugging was broken on arm64 macOS
- UI: the navigator wouldn't remain hidden across IDB loads
- UI: in the "Structures" window, jumping to a type (e.g., through xref) that's not currently visible because it's not part of the selection in the left-hand list, could fail to make it visible
- UI: if no disassembly view is available at IDB load-time, some actions (e.g., UnHide) could be unavailable in certain widgets such as "Structures"
