Netsweeper is pleased to announce the Client Filter 13.50 GA release. This is the first GA release supporting Windows ARM installations along with full support for the latest version of MacOS. The Client Filter 13 release-series introduced a new configuration UI supported on all Client Filter platforms, from Windows, MacOS, iOS, and Android. The Windows and MacOS release now store this configuration in a database to avoid issues with AV software which may lock the configuration file and cause configuration changes to fail.

The 13.50 GA release is available in the Chrome, Apple, and Android stores in order to allow customers to start taking advantage of the major improvements in the Client Filter 13 release series.

Bug	CF-245	Enabling or disabling nsdivert.sys would stop networking until the NSFX service was restarted.
Bug	CF-567	Our pushed Exception List was being blocked by certain antivirus scanners.
Improvement	CF-568	Exposed the ALE redirect checkbox in the Client Filter configuration window.
Bug	CF-571	We now disable ALE redirection when HTTPS filtering is disabled.
Bug	CF-581	Added support for filtering downloads with the Chrome browser.

Bug	CF-739	ALE Redirect Mode would continue to redirect port traffic for existing connections after disabling filtering.
Improvement	CF-764	The Chrome MV3 extension will no longer send tab updates for any non Hypertext-based URLs. This is intended to avoid scanning extension pages and other built in Chrome pages which we could not previously filter.
Improvement	CF-772	The MacOS Preference Pane was missing the 'Uninstall' button in the 13.10 and 13.20 releases.
Bug	CF-776	The login.liger-event would fail to send for the Android and iOS VPN Client, resulting in the Override key not working.
Bug	CF-783	The Windows Client UI would fail display any log or Request Log data.
Bug	CF-792	Addressed inconsistencies with the nMonitor UI, ensuring that all 'disable' options are labelled clearly.
Bug	CF-800	The login.liger event was not being triggered upon Brand changes.
Improvement	CF-814	Recompiled the Android VPN App to support 16KB memory page sizes.
Improvement	CF-815	Improved Chrome error handling when using the chrome.runtime.sendMessage function.
Bug	CF-816	Resolved an issue where the nMonitor engine could cause the weight of detection to be off by small factor in some instances.
Bug	CF-817	'ReplaceFileA' has been deprecated, we now use a custom 'libnscf_util_rename_file()' utility.
Improvement	CF-820	Added the ability to log data to stdout/console output with the Windows Client Filter.
Improvement	CF-821	Added the ability for the tray launcher to run in debug builds and with the address sanitizer enabled.
Improvement	CF-822	We now run the WFP Filtering rules for both IP addresses and Ports before the ALE redirect occurs, ensuring we can consistently Filter what we send to the ALE redirect for processing by NSProxy.
Bug	CF-823	Android VPN: Ensured the GUI will wait for the 'initLibrary' when running on Android.
Improvement	CF-825	Our Chrome MV3 Client will now trigger the Event processes (init, app.start, getconfig, Domain User Group, et cetera) when a Filtered Event occurs; improving compatibility with devices in Chrome's Ephemeral mode that startup without internet connectivity.
Bug	CF-826	We were not starting the failed Domain User Group timer properly after a failure on the Chrome mv3 manifest.
Bug	CF-827	Chrome MV3 UI, pushed configs, and MDM configs could not clear any arguments for values set to null.
Improvement	CF-830	The Chrome Client Filter no longer requires browsingData permission.
Improvement	CF-831	Chrome Client Filter MV3 extension now declares usage of SharedArrayBuffer.
Bug	CF-832	Chrome MV3 Google Workspace settings were not monitored for changes, so we would not detect and trigger reconfigurations when Google Workspace policies were updated.
Improvement	CF-833	Upgraded the Chrome MV3 extensions to use the CRX3 format, allowing us to rollback versions and force install the MV3 from the .xml file.
Improvement	CF-834	Added a MacOS-specific flag (4194304) in order to force the VPN back on if it gets disabled during user login. This will prevent possible instances of slow filtering with MacOS14 and MacOS15.
Improvement	CF-835	The Chrome MV3 Client Filter now processes the system and user cookies separately to avoid startup race conditions.
Bug	CF-837	Window x64/ARM Client Filter Settings 'Request' tab was not presenting Request data in the 13.30 release.
Improvement	CF-839	New nsdivert64.sys 2.3.8 build adds improvements for ALE IPv6 filtering and ALE flow filter support.
Bug	CF-840	Reused TCP port numbers could cause flow state to be ignored.
Bug	CF-843	The Config UI on MacOS was unable to access the clipboard, resulting in copy/paste functionality not working.
Bug	CF-845	MacOS Settings were failing to detect dark/light mode selections in the Config UI.
Improvement	CF-847	Added a 'Clear Logs' button into the Client Filter UI's 'Request and Filter' Logs interface.
Bug	CF-848	The Chrome client could overwrite the user cookie with a system cookie from the login.liger-event response, clearing the User/Group information.
Bug	CF-849	The 'App start' Event was not triggering upon changes to the Policy Server or Brand configurations.

Bug	CF-860	When the start app message would fail, the system tray can fail to resend it, causing the DUG message to also fail to send.
