# IDA 7.6sp1

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

golang:

* 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"
