+spicyjpeg:
+
+- libc: Fixed bugs in some string manipulation and number parsing functions.
+ Added `memccpy()`. Removed the `SYSTEM.CNF` argument parser as it would
+ interfere with manual argc/argv passing in some edge cases.
+
+- psxgpu: Added `IsIdleGPU()` and fixed a bug in `SetVideoMode()`. Added new
+ "tagless" primitive structures with the `_T` suffix (e.g. `POLY_FT4_T`,
+ `SPRT_T`, ...) and related macros (`setPolyFT4_T()`, `setSPRT_T()`, ...) that
+ can be used to group multiple primitives into a single display list packet
+ for better performance. Fixed some macros not working properly with negative
+ values. Renamed `DR_MASK` and `setDrawMask()` to `DR_STP` and `setDrawStp()`
+ respectively for consistency with the official SDK.
+
+- psxcd: Added `CdUnlock()`. Improved reliability of `CdGetRegion()` on early
+ Japanese console models.
+
+- psxetc: Added `SetDMAPriority()` and `GetDMAPriority()`.
+
+- psxapi: Added PCDRV (host file I/O) API, declared in the `psxsn.h` header.
+
+- psxpress: Fixed bugs in the MDEC API. Added support for bitstream version 3
+ to the GTE-accelerated decoder. Replaced `DecDCTvlcCopyTable()` with
+ `DecDCTvlcCopyTableV2()` and `DecDCTvlcCopyTableV3()` for better control over
+ how much of the scratchpad is used for lookup tables.
+
+- examples: `mdec/strvideo` is now (finally) functional on real hardware and
+ can properly detect the end of a video file even if immediately followed by
+ another video on the disc. Added previously missing CD image dependencies to
+ the CMake scripts of the examples that make use of CD images.
+
+- tools: `elf2x` no longer adds region strings to converted executables, fixing
+ issues with DuckStation's region autodetection. Updated `mkpsxiso` to 2.03 in
+ order to fix a bug with its thread pool implementation on Linux.
+
+- Updated binutils and recompiled the GCC toolchain with the
+ `--disable-hosted-libstdcxx` option, allowing a subset of the C++ STL to be
+ used in PSn00bSDK projects.

## Note regarding C++ support
-C++ support in PSn00bSDK, besides compile-time features like `constexpr`, only
-goes as far as basic classes, namespaces and the ability to dynamically create
-and delete class objects at any point of the program. The required dependencies
-(which are just wrappers around `malloc()` and `free()`) are supplied by `libc`.
+C++ support in PSn00bSDK is limited to the freestanding subset of the standard
+library provided by GCC, which includes most metaprogramming and compile-time
+utilities but not higher level functionality that requires runtime support such
+as exceptions, containers or streams. Basic C++ features that only depend on the
+compiler (classes, templates, `constexpr` and so on) are fully supported.
-Standard C++ libraries are not implemented and likely never going to be
-implemented due to bloat concerns that it may introduce. Besides, the official
-SDK lacks full C++ support as well.
+Implementing a full STL, while technically possible, is currently out of the
+scope of PSn00bSDK. There are other PS1 SDKs that provide an STL, such as
+[psyqo](https://github.com/grumpycoders/pcsx-redux/tree/main/src/mips/psyqo),
+and they might be a better fit for your project if you plan to make heavy use of
+C++ features.
