- For details see Changes.rst
- Windows Installer: fix CVE-2023-7235 where installing to a non-default
directory could lead to a local privilege escalation. Reported by Will Dormann.
- Add support for building with mbedTLS 3.x.x
- New option --force-tls-key-material-export to only accept clients
that can do TLS keying material export to generate session keys
(mostly an internal option to better deal with TLS 1.0 PRF failures). - Windows: bump vcpkg-ports/pkcs11-helper to 1.30
- Log incoming SSL alerts in easier to understand form and move logging
from --verb 8 to --verb 3. - protocol_dump(): add support for printing --tls-crypt packets
- License change is now complete, and all code has been re-licensed
under the new license (still GPLv2, but with new linking exception
for Apache2 licensed code). See COPYING for details.
Code that could not be re-licensed has been removed or rewritten. - The original code for the --tls-export-cert feature has been removed
(due to the re-licensing effort) and rewritten without looking at the
original code. Feature-compatibility has been tested by other developers,
looking at both old and new code and documentation, so there *should*
not be a user-visible change here. - IPv6 route addition/deletion are now logged on the same level (3) as
for IPv4. Previously IPv6 was always logged at --verb 1. - Better handling of TLS 1.0 PRF failures in the underlying SSL library
(e.g. on some FIPS builds) - this is now reported on startup, and
clients before 2.6.0 that can not use TLS EKM to generate key material
are rejected by the server. Also, error messages are improved to see
what exactly failed.
- FreeBSD: for servers with multiple clients, reporting of peer traffic
statistics would fail due to insufficient buffer space (Github: #487)
- Security fix, see above
- Built against OpenSSL 3.2.0
- Included openvpn-gui updated to 11.47.0.0
- Windows GUI: always update tray icon on state change (Github: #669)
(for persistent connection profiles, "connecting" state would not show)
