WebTitan OTG 2 for Windows Release Notes
The introduction of the OTG 2 family of agents saw our WebTitan OTG 1 agent being re-architected as a single-threaded application, meaning that the WebTitan OTG 2 agents are more stable and secure and require less CPU overhead from the user machine.
The WebTitan OTG 2 agent family offers several other improvements:
You can remotely manage and configure OTG 2 devices after installation from WebTitan, using the new device management UI.
You can view detailed device information on all your devices in WebTitan and apply global or individual configuration changes.
Reliance on a user's IP address has been removed, with OTG 2 now using an EDNS tag to identify a user and their device.
You can now automatically assign a specific policy to new devices during installation.
OTG 2 uses a customer-specific install key that improves security during installation. The install key can also be regenerated in the WebTitan UI if necessary.
WebTitan OTG 2 for Windows 2.2.5
Released: December 2024
We’re excited to announce the release of OTG 2.2.5. This update brings key improvements, bug fixes, and enhanced stability to make your experience even better.
Why Upgrade?
This release focuses on delivering a more stable and efficient OTG. The fixes and enhancements ensure smoother configuration management, better performance, and stronger security. Whether you’re working with IPv6 networks, using VPN adapters, or managing DNS settings, OTG 2.2.5 is designed to make these processes more reliable and seamless.
We recommend updating to OTG 2.2.5 to take full advantage of these improvements.
What has been improved?
VPN Adapter Management: Enhanced detection and management of VPN adapters. OTG now avoids modifying their DNS configurations.
DNS Configuration Updates: For Windows 10 (build 19041 and above), OTG now uses a built-in Windows API to change DNS settings for improved reliability.
Logging: Refined logging output to make it less verbose while maintaining essential details.
Registry Updates: Implemented registry flushing after updating the “DNS Addresses” value to ensure consistent configuration.
Sleep/Resume Handling: Enhanced OTG’s ability to handle device sleep and resume events for smoother operation.
IPv6 Support: Improved support for IPv6 networking.
Network Changes: Enhanced detection of network changes for better adaptability.
What has been fixed?
Configuration Deletion Bug: Fixed an issue where OTG could delete a valid configuration if the WTC was unavailable.
IPv6 Local DNS Server Address Bug: Resolved an issue affecting the IPv6 Local DNS Server address.
DNS Registry Repetition: Addressed a bug that caused DNS server addresses to be repeated under the “DNS Addresses” registry value.
ConfigurationGrabber Exception: Fixed an error in ConfigurationGrabber that prevented proper parsing of DNS address lists.
Library Updates
OpenSSL: Upgraded to version 3.3.2 to stay current with security updates.
Unbound: Updated to version 1.22 for improved DNS resolution capabilities.
WebTitan OTG 2 for Windows 2.1
Released: November 2021
WebTitan OTG 2 for Windows 2.1 includes some improvements, but it is primarily a bug fix release to strengthen and enhance the product.
What has been improved?
Improvements have been made on the client side to limit instances of a "blocked" status intermittently occurring. Further improvements are planned in later releases.
Additional querying of local DHCP settings has been added for use when detaching from the network interface. This improvement fixed an issue affecting some VPNs, where VPN settings would be kept.
What has been fixed?
Issues causing an OTG 2 device to continuously request reconfiguration have been addressed. This release limits the frequency of such requests.
Resolved an issue causing IPv6 addresses to be stored incorrectly instead of reverting to the correct value.
An issue causing nslookup to not work due to an incorrect IPv6 address has been resolved.
An issue where a user was not being created on WebTitan following OTG 2 install has been resolved.
