# IDA 9.0sp1

**IDA 9.0.20241216 (SP1)** December 19, 2024

This Service Pack of IDA 9.0 focuses on bugfixes, along with IDAPython API and SDK enhancements, introducing new, simplified endpoints. You can download the latest IDA installer from [My Hex-Rays portal](https://my.hex-rays.com/dashboard/download-center/downloads).

## IDA Feeds improvements

We streamlined the IDA Feeds plugin execution and resolved issues with loading when idalib could not be located or was not correctly installed. Last but not least, we delivered UI enhancements to make the plugin experience more intuitive.

**See also:**

* Take a look at the [IDA Feeds installation and configuration guide](https://docs.hex-rays.com/9.0sp1/user-guide/plugins/plugins-shipped-with-ida/ida-feeds)

**Complete IDA Feeds changelist:**

* added undo/redo context menu options for standalone app
* allow running the plugin without having to install and configure the idapro python module
* fall back to sequential probing when rpyc module is not available
* fill the already applied signatures on plugin initialization
* various usability and performance improvements

## IDAPython / SDK improvements

We've added several helpers to improve the user experience using our APIs. These new endpoints, among other things, streamline managing and operating on types.

In the spirit of further improving accessibility & usage of our API, we also:

* updated the [Porting Guide](https://docs.hex-rays.com/9.0sp1/developer-guide/idapython/idapython-porting-guide-ida-9), considering recent API improvements.
* prepared new [examples](https://docs.hex-rays.com/9.0sp1/developer-guide/idapython/idapython-examples), mostly under **Working with types** category.
* revamped the IDAPython [reference documentation](https://python.docs.hex-rays.com/) to improve cross-referencing.

We've also added support for **Python 3.13**.

**IDAPython / SDK changes:**

* addded support for Python 3.13
* added `tinfo_t` convenience constructors
  * `tinfo_t(c_decl:str)` (to parse a C type definition)
  * `tinfo_t(ordinal=N:int)` to fetch by ordinal
  * `tinfo_t(name=N:str)` to fetch by name
  * `tinfo_t(tid=N:int)` to fetch by `tid_t`
* added `tinfo_t.add_edm` to simplify building enumerations
* added `tinfo_t.add_udm` convenience methods
* added `tinfo_t.get_udm` (either by name, or by index)
* added `tinfo_t.get_udm_by_offset`
* added `tinfo_t` iterators, for easy member manipulation:
  * `tinfo_t.iter_struct`
  * `tinfo_t.iter_union`
  * `tinfo_t.iter_udt`
  * `tinfo_t.iter_enum`
* added `til_t.get_named_type` and `til_t.get_numbered_type`, making it more idiomatic to retrieve types from a library
* added `til_t.named_types` and `til_t.numbered_types` generators
* added `udt_type_data_t.get_best_fit_member`
* added convenience `funcarg_t` constructors
* added convenience `udm_t` constructors
* added convenience `edm_t` constructor
* added many new examples of using core API functions into `examples/types/`
* added `empty()` method to udt member type (`udm_t`) and enum constant type (`edm_t`)
* `func_type_data_t` now defaults to `CM_CC_UNKNOWN` calling convention
* added `append()` and `extend()` to all `qvector`-based types
* added `get_process_options2` to retrieve the list of environment variables
* the `displayhook` now uses `__repr__`, and not `__str__`, to print information
* expose `get_undo_action_label()`, `get_redo_action_label()`
* expose needed functions for checking if a file is a startup signature

## UI improvements

**Complete UI changelist:**

* do not offer to apply startup signatures by default
* local types: allow adding comments on gaps by creating a dummy field automatically
* local types: enabled "Remove gap" action on padding bytes at the end of fixed layout struct
* local types: removed "repeatable" checkbox from the comment form since all such comments are repeatable

## Other improvements

* installer: install `defs.h` header with decompiler helpers into `include/`
* kernel: added new parameters REGTRACK\_MAX\_XREFS, REGTRACK\_MAX\_BBLK\_INSNS, REGTRACK\_MAX\_VALS to limit tracking in complex binaries
* licensing: show the number of floating license seats available in the "License manager" dialog
* lumina: improved the `lumina_server`'s `--recreate-schema` help text
