Standard plugins

• DSCU: support loading (and symbolicating) global offset tables from iOS16
• dyldcaches
• golang: support for go1.18 (function names, types)
• OBJC: improved decompilation of functions that use objc_alloc_init() to initialize Objective-C objects
• OBJC: improved decompilation of Objective-C binaries by creating artificial imports for to methods not present in the idb
• patfind: new plugin to discover code patterns in otherwise unmarked binaries

Scripting & SDK

• IDAPython: removed Python 2 support
• SDK: added a new method qstring::rtrim() to trim whitespaces
• SDK: added get_stdact_descs() for choosers for customizing the standard actions (Insert, Delete, Edit, Refresh)
• SDK: added wildcard_path_match(), that can match entire paths against a pattern following the same rules as a shell (e.g. ** and ranges like [a-z])
• SDK: improved comment for has_external_refs()
• SDK: support usage of qstring in hashed STL containers

UI:

• UI: the command-line arguments in the Debugger>Process options... dialog are no longer limited to 1024 characters

Decompilers:

• added option HO_PROP_VOLATILE_LDX to propagate load instructions without checking for volatile memory access
• added support for outlined functions
• arm: recognize thunk functions with suffixes _from_thumb, _from_arm, _veneer
• improve handling of scattered return values (=using mutiple registers/stack locations)
• new decompiler: HEXARC (for the ARC processor family)
• pc: control register maniplation intrinsics (e.g __writecr0) work with 32-bit values in 32-bit mode
• support WCHAR, wchar16_t, wchar32_t as character element types
