OPENVPN 2.5.4 -- RELEASED 5 OCT, 2021
The OpenVPN community project team is proud to release OpenVPN 2.5.4. This
release include a number of fixes and small improvements. One of the fixes is to
password prompting on windows console when stderr redirection is in use - this
breaks 2.5.x on Win11/ARM, and might also break on Win11/amd64. Windows
executable and libraries are now built natively on Windows using MSVC, not
cross-compiled on Linux as with earlier 2.5 releases. Windows installers include
updated OpenSSL and new OpenVPN GUI. The latter includes several improvements,
the most important of which is the ability to import profiles from URLs where
available. Installer version I602 fixes loading of pkcs11 files on Windows.
Installer version I603 fixes a bug in the version number as seen by Windows (was
2.5..4, not 2.5.4). Installer I604 fixes some small Windows issues.

IMPORTANT NOTICES
BF-CBC CIPHER IS NO LONGER THE DEFAULT
Cipher handling for the data channel cipher has been significantly changed
between OpenVPN 2.3/2.4 and v2.5, most notably there are no "default cipher
BF-CBC" anymore because it is no longer considered a reasonable default. BF-CBC
is still available, but it needs to be explicitly configured now.
For connections between OpenVPN 2.4 and v2.5 clients and servers, both ends will
be able to negotiate a better cipher than BF-CBC. By default they will select
one of the AES-GCM ciphers, but this can be influenced using the --data-ciphers
setting.
Connections between OpenVPN 2.3 and v2.5 that have no --cipher setting in the
config (= defaulting to BF-CBC and not being negotiation-capable) must be
updated. Unless BF-CBC is included in --data-ciphers or there is a "--cipher
BF-CBC" in the OpenVPN 2.5 config, a v2.5 client or server will refuse to talk
to a v2.3 server or client, because it has no common data channel cipher and
negotiating a cipher is not possible. Generally, we recommend upgrading such
setups to OpenVPN 2.4 or v2.5. If upgrading is not possible we recommend adding
data-ciphers AES-256-GCM:AES-128-GCM:AES-128-CBC (for v2.5+) or cipher
AES-128-CBC (v2.4.x and older) to the configuration of all clients and servers.
If you really need to use an unsupported OpenVPN 2.3 (or even older) release and
need to stay on BF-CBC (not recommended), the OpenVPN 2.5 based client will need
a config file change to re-enable BF-CBC. But be warned that BF-CBC and other
related weak ciphers will be removed in coming OpenVPN major releases.
For full details see the"Data channel cipher negotiation" section on the man
page.
CONNECTIVITY TO SOME VPN SERVICE PROVIDER MAY BREAK
Connecting with an OpenVPN 2.5 client to at least one commercial VPN service
that
implemented their own cipher negotiation method that always reports back that it
is using BF-CBC to the client is broken in v2.5. This has always caused warning
about mismatch ciphers. We have been in contact with some service providers and
they are looking into it. This is not something the OpenVPN community can fix.
If your commercial VPN does not work with a v2.5 client, complain to the VPN
service provider.
More details on these new features as well as a list of deprecated features and
user-visible changes are available in Changes.rst.

OPENVPN 2.5.3 -- RELEASED 17 JUNE, 2021
The OpenVPN community project team is proud to release OpenVPN 2.5.3. Besides a

OPENVPN 2.5.2 -- RELEASED 21 APRIL, 2021
The OpenVPN community project team is proud to release OpenVPN 2.5.2. It fixes
two related security vulnerabilities (CVE-2020-15078) which under very specific
circumstances allow tricking a server using delayed authentication (plugin or
management) into returning a PUSH_REPLY before the AUTH_FAILED message, which
can possibly be used to gather information about a VPN setup. In combination
with "--auth-gen-token" or a user-specific token auth solution it can be
possible to get access to a VPN with an otherwise-invalid account. OpenVPN 2.5.2
also includes other bug fixes and improvements. Updated OpenSSL and OpenVPN GUI
are included in Windows installers.

AES-128-CBC (v2.4.x and older) to the configuration of all clients and servers.
If you really need to use an unsupported OpenVPN 2.3 (or even older) release and
need to stay on BF-CBC (not recommended), the OpenVPN 2.5 based client will need
a config file change to re-enable BF-CBC. But be warned that BF-CBC and other
related weak ciphers will be removed in coming OpenVPN major releases.
For full details see the"Data channel cipher negotiation" section on the man
page.
CONNECTIVITY TO SOME VPN SERVICE PROVIDER MAY BREAK
Connecting with an OpenVPN 2.5 client to at least one commercial VPN service
that
implemented their own cipher negotiation method that always reports back that it
is using BF-CBC to the client is broken in v2.5. This has always caused warning
about mismatch ciphers. We have been in contact with some service providers and
they are looking into it. This is not something the OpenVPN community can fix.
If your commercial VPN does not work with a v2.5 client, complain to the VPN
service provider.
More details on these new features as well as a list of deprecated features and
user-visible changes are available in Changes.rst.

IMPORTANT NOTICES
BF-CBC CIPHER IS NO LONGER THE DEFAULT
Cipher handling for the data channel cipher has been significantly changed
between OpenVPN 2.3/2.4 and v2.5, most notably there are no "default cipher
BF-CBC" anymore because it is no longer considered a reasonable default. BF-CBC
is still available, but it needs to be explicitly configured now.
For connections between OpenVPN 2.4 and v2.5 clients and servers, both ends will
be able to negotiate a better cipher than BF-CBC. By default they will select
one of the AES-GCM ciphers, but this can be influenced using the --data-ciphers
setting.
Connections between OpenVPN 2.3 and v2.5 that have no --cipher setting in the
config (= defaulting to BF-CBC and not being negotiation-capable) must be
updated. Unless BF-CBC is included in --data-ciphers or there is a "--cipher
BF-CBC" in the OpenVPN 2.5 config, a v2.5 client or server will refuse to talk
to a v2.3 server or client, because it has no common data channel cipher and
negotiating a cipher is not possible. Generally, we recommend upgrading such
setups to OpenVPN 2.4 or v2.5. If upgrading is not possible we recommend adding
data-ciphers AES-256-GCM:AES-128-GCM:AES-128-CBC (for v2.5+) or cipher
AES-128-CBC (v2.4.x and older) to the configuration of all clients and servers.
If you really need to use an unsupported OpenVPN 2.3 (or even older) release and
need to stay on BF-CBC (not recommended), the OpenVPN 2.5 based client will need
a config file change to re-enable BF-CBC. But be warned that BF-CBC and other
related weak ciphers will be removed in coming OpenVPN major releases.
For full details see the"Data channel cipher negotiation" section on the man
page.

OPENVPN 2.4.11 -- RELEASED 21 APRIL, 2021
The OpenVPN community project team is proud to release OpenVPN 2.4.11. It fixes
two related security vulnerabilities (CVE-2020-15078) which under very specific
circumstances allow tricking a server using delayed authentication (plugin or
management) into returning a PUSH_REPLY before the AUTH_FAILED message, which
can possibly be used to gather information about a VPN setup. This release also
includes other bug fixes and improvements. The I602 Windows installers fix a
possible security issue with OpenSSL config autoloading on Windows
(CVE-2021-3606). Updated OpenSSL and OpenVPN GUI are included in Windows
installers.

A summary of the changes is available in Changes.rst, and a full list of changes
is available here.
Please note that LibreSSL is not a supported crypto backend. We accept patches
and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions
of LibreSSL break API compatibility we do not take responsibility to fix that.
Also note that Windows installers have been built with NSIS version that has
been patched against several NSIS installer code execution and privilege
escalation problems. Based on our testing, though, older Windows versions such
as Windows 7 might not benefit from these fixes. We thus strongly encourage you
to always move NSIS installers to a non-user-writeable location before running
them.
Please note that OpenVPN 2.4 installers will not work on Windows XP. The last
OpenVPN version that supports Windows XP is 2.3.18, which is downloadable as
32-bit and 64-bit versions.
If you find a bug in this release, please file a bug report to our Trac bug
tracker. In uncertain cases please contact our developers first, either using
the openvpn-devel mailinglist or the developer IRC channel (#openvpn-devel at
irc.libera.chat). For generic help take a look at our official documentation,
wiki, forums, openvpn-users mailing list and user IRC channel (#openvpn at
irc.libera.chat).
Important: you will need to use the correct installer for your operating system.
The Windows 10 installer works on Windows 10 and Windows Server 2016/2019. The
Windows 7 installer will work on Windows 7/8/8.1/Server 2012r2. This is because
of Microsoft's driver signing requirements are different for kernel-mode devices
drivers, which in our case affects OpenVPN's tap driver (tap-windows6).
OPENVPN 2.4.10 -- RELEASED 9 DECEMBER, 2020
This is primarily a maintenance release with bugfixes and small improvements.
Windows installers include the latest OpenSSL version (1.1.1i) which includes
security fixes.
A summary of the changes is available in Changes.rst, and a full list of changes

OPENVPN 2.4.9 -- RELEASED 17 APRIL, 2020
This is primarily a maintenance release with bugfixes and improvements. This
release also fixes a security issue (CVE-2020-11810, trac #1272) which allows
disrupting service of a freshly connected client that has not yet not negotiated
session keys. The vulnerability cannot be used to inject or steal VPN traffic.
A summary of the changes is available in Changes.rst, and a full list of changes
is available here.
Please note that LibreSSL is not a supported crypto backend. We accept patches
and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions

them. We are moving to MSI installers in OpenVPN 2.5, but OpenVPN 2.4.x will
remain NSIS-only.
Compared to OpenVPN 2.3 this is a major update with a large number of new
features, improvements and fixes. Some of the major features are AEAD (GCM)
cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack
support and more seamless connection migration when client's IP address changes
(Peer-ID). Also, the new --tls-crypt feature can be used to increase users'
connection privacy.
OpenVPN GUI bundled with the Windows installer has a large number of new
features compared to the one bundled with OpenVPN 2.3. One of major features is
the ability to run OpenVPN GUI without administrator privileges. For full
details, see the changelog. The new OpenVPN GUI features are documented here.

The Windows 10 installer will not work on Windows 7/8/8.1/Server 2012r2. This is
because Microsoft's driver signing requirements and tap-windows6. For the same
reason you need to use an older installer with Windows Server 2016. This older
installer has a local privilege escalation vulnerability issue which we cannot
resolve for Windows Server 2016 until tap-windows6 passes the HLK test suite on
that platform. In the meanwhile we recommend Windows Server 2016 users to avoid
installing OpenVPN/tap-windows6 driver on hosts where all users can't be
trusted. Users of Windows 7-10 and Server 2012r2 are recommended to update to
latest installers as soon as possible.

OPENVPN 2.4.6 -- RELEASED 24 APRIL, 2018
This is primarily a maintenance release with minor bugfixes and improvements,
and one security relevant fix for the Windows Interactive Service. Windows
installer includes updated OpenVPN GUI and OpenSSL. Installer I601 included
tap-windows6 driver 9.22.1 which had one security fix and dropped Windows Vista
support. However, in installer I602 we had to revert back to tap-windows 9.21.2
due to driver getting reject on freshly installed Windows 10 rev 1607 and later
when Secure Boot was enabled. The failure was due to the new, more strict driver
signing requirements. The 9.22.1 version of the driver is in the process of
getting approved and signed by Microsoft and will be bundled in an upcoming
Windows installer.
Please note that LibreSSL is not a supported crypto backend. We accept patches
and we do test on OpenBSD 6.0 which comes with LibreSSL, but if newer versions
of LibreSSL break API compatibility we do not take responsibility to fix that.
Also note that Windows installers have been built with NSIS version that has
been patched against several NSIS installer code execution and privilege
escalation problems. Based on our testing, though, older Windows versions such
as Windows 7 might not benefit from these fixes. We thus strongly encourage you
to always move NSIS installers to a non-user-writeable location before running
them. Our long-term plan is to migrate to using MSI installers instead.
Compared to OpenVPN 2.3 this is a major update with a large number of new
features, improvements and fixes. Some of the major features are AEAD (GCM)
cipher and Elliptic Curve DH key exchange support, improved IPv4/IPv6 dual stack
support and more seamless connection migration when client's IP address changes
