* Recursive PCI-bus enumeration;
* Better error reporting;
* Support for arm64 fp;
* Automatic libc-style system call stubs;
* Improved console I/O;
* virtio block driver;
* signals support
* ANSI-colored output;
…and much more!

We have also been hard at work increasing the number of available applications 
and libraries supported by Unikraft, including:

* tflite - ML for Mobile and Edge Devices
* dnnl - Intel's Deep Neural Network Library
* nnpack - an acceleration package for neural network computations
* tlsf - Memory allocator real time embedded systems
* allocbuddy - Binary buddy memory allocator
* tinyalloc - A tiny allocator designed for tiny embedded systems
* mimalloc - A general purpose allocator with excellent performance 
characteristics
* nettle - A low-level cryptographic library
* gemmlowp - Low-precision matrix multiplication
* liblzma - A compression library with an API similar to that of zlib
* protobuf - Google’s language-neutral, platform-neutral, extensible mechanism 
for serializing structured data.
* zydis - Fast and lightweight x86/x86-64 disassembler library
* farmhash - FarmHash provides hash functions for strings and other data
