New beta version – build 26.4.10921

Hello everyone,

there is a new beta version ready - build 26.4.10921.

Release notes

:new_button: What is New

Network, web protection & Safeweb/Secure DNS

  • More robust Secure DNS failover
    When no DNS-over-HTTPS server is reachable, the backoff logic and retry intervals are now respected instead of collapsing back to rapid retries, reducing unnecessary traffic and timeouts.
  • Configurable behaviour under repeated DNS errors
    Admin-level settings can now limit how often new server lists are downloaded and whether DNS server re-selection should be triggered at all when persistent errors are detected.
  • More defensive CSV parsing of server lists
    The parser for downloaded server lists has been replaced with an RFC-compliant, more robust implementation to better handle malformed data and avoid resource exhaustion.

:lady_beetle: What Was Fixed

VPN stability

  • Top VPN crash during shutdown fixed
    A null-pointer dereference in the VPN service shutdown path (seen as a top crash in telemetry) has been fixed, improving reliability when turning VPN off or shutting down Windows.

TuneUp – Data Recovery

  • Excluded folders are now respected on all supported file systems
    In Data Recovery, folders marked as excluded (including system folders) are now correctly skipped even on FAT32 and exFAT volumes, so scans and results no longer include content the user opted out of.
