[libusb] Announcing libusb v1.0.30

[Tormod V. <lis...@gm...>]

We are happy to announce the final release of libusb 1.0.30.

It features two new API functions, libusb_get_device_string() and
libusb_get_session_data().

For Windows there are two new major features that have been in the
works for a long time. One is the RAW_IO support that can greatly
enhance throughput on bulk transfers. The other is the optional
support for hotplug. There are still issues with e.g. composite
devices, so it is not enabled by default, and must be enabled at build
time. The 7z archive with Windows binaries includes both hotplug and
default build variants (also for ARM64) in the VS2025 folder. The goal
is to enable hotplug by default in future releases.

ChangeLog with most important changes since previous release 1.0.29:
* Add hotplug support on Microsoft Windows
* Add RAW_IO support in WinUSB backend
* Work around a macOS 26 Tahoe compatibility breakage due to Apple
changing kUSBHostPortPropertyPortNumber
* Add new API libusb_get_device_string() to access device strings
without opening the device
* Add new API libusb_get_session_data() which returns the OS-specific handle
* Fix device removal races on non-hotplug builds
* Improve descriptor parsing memory safety
* On Darwin, fix concurrency issues
* On Android, fix intermittent failures in get_usbfs_fd()
* On Windows, fix bus number assignment for root hub device,
preventing duplicate bus number assignments
* Fix compilation with Microsoft Visual Studio 2026
* Fix various compiler warnings, improved tests and examples

The 1.0.30 release was made possible by the contributions (84 commits)
from 27 patch submitters (14 new) - see below git shortlog - plus
everyone who contributed with issue reporting, discussions and
testing. Most prominently, we now have Sean McBride and Sylvain Fasel
in the core development team and they have massively contributed to
implementation and review of new features as well as bug fixing and
code maintenance. As many other projects, we start to feel the "heat"
of LLM-assisted contributions so we are more than ever grateful for
critical reviews.

Please note that after this release, it is planned to put the old
"nano" version (visible in debug logs and per libusb_get_version) to
rest, and replace it with the more common "git describe" format, see
https://github.com/libusb/libusb/pull/1812 . Also support for
Microsoft VS2013 and VS2015 compiler environments is planned to be
removed (and binary releases trimmed), see
https://github.com/libusb/libusb/pull/1784 . If any of this is a
concern to you, please get involved.


The release source code tarball can be downloaded here:
https://github.com/libusb/libusb/releases/download/v1.0.30/libusb-1.0.30.tar.bz2

An archive of Windows binaries can be downloaded here:
https://github.com/libusb/libusb/releases/download/v1.0.30/libusb-1.0.30.7z

Note that the tarball includes a configure script so unlike a git
checkout it is not necessary to bootstrap it with autoconf.

On behalf of the libusb development community,
Tormod
