IDA 8.3.230608 June 8, 2023
We have further improved IDA64 so that it can be a complete replacement for the legacy 32-bit IDA in all situations. To ease the migration, we implemented a feature to convert the legacy .idb databases to .i64 ones (codenamed CVT64).
The 32-bit IDA is now considered deprecated and will likely go away at some point.
Improved UI performance on some strategic fronts. For example, slower autoanalysis of Dyld Shared Cache's due to the "Functions" window (whether filtered or not) is a thing of the past.
It is now possible to specify a (HTTP CONNECT-style) proxy for connecting to the Vault server.
During a merging session, you can pick a chunk to resolve a conflict using context menu instead of the toolbar.
The licensing logic was improved:
Previously, when some licenses expired, the Vault server would refuse to work until the number of users was reduced to the count of the active licenses. Now it will continue working but simply refuse new license checkouts in such situation.
IDA was relying on the local ida.key file and displaying the expiration date from it, even if the license was updated on Vault server. Now IDA Teams does not use the local ida.key at all but only information from the server.
Our free offer for educational institutions gained a cloud decompiler for x86/x64 and the file size limit has been lifted.
The decompiler's IDA Python API (ida_hexrays module) now works with the cloud decompilers available in IDA Home
PPC processor module gained support for the LSP extension, as well as the new Power ISA 3.1 instructions
ARM module now shows symbolic names for well-known ARM64 system registers
MIPS and RISC-V modules have improved register value tracking which should lead to better analysis and more discovered cross-references
DEX module and loader now support the new features added in the DEX 039 format (Android 9 and 10)
PC: instructions with three or more operands (such as imul or vinsertps) can support properly distinct types for each operand. In fact, this applies to instructions with three or more operands in all processors.
ESP: a new loader, supporting the common file format used for the Espressif ESP line of chips
Cortex-M: a new loader for Cortex-M raw binary firmware, supports ARMv6-M to ARMv8-M and load base autodetection

OBJC: added support for Objective-C optimizations introduced in iOS16 (stubs for objc_msgSend with common selectors and custom wrappers for retain/release)
it is now possible to disable some optional optimizations performed by default. This may be useful for plugin writers doing their own analysis on microcode
