Tor Browser፦ ሁሉም ስሪቶች እና የቆዩ ስሪቶች

Tor Browser 15.0.26 is now available from the Tor Browser download page and also from our distribution directory.
This version blocks compromised intermediate eMudhra certificates.
Note: the updated revocation database can take some minutes to build on first browser startup.

The full changelog since Tor Browser 15.0.25 is:
- All Platforms
- Bug tor-browser#45397: Update CA intermediates and other settings dumps
- applications
- releases

All Platforms
- Updated Tor to 0.4.9.14
- Updated NoScript to 13.6.36.1984
- Updated OpenSSL to 3.5.9

Build System
All Platforms
- Bug tor-browser-build#41885: Update changelogs as a last step in relprep.py
Windows
- Bug tor-browser-build#41890: Update sign-exe wrapper to use new Windows signing cert

Windows Package Signature Issue
The DigiCert EV code‑signing certificate we use to sign Windows installation packages expired on September 1st and is being renewed. This delay caused Windows users installing Tor Browser 15.0.21 and 15.0.22 from scratch to see “bad signature” warnings. As a temporary workaround, Windows users can install Tor Browser 15.0.20 (the latest correctly signed version) and rely on automatic updates (signed with a different key) to reach the current version. Users who prefer to download the latest version directly, ignoring the certificate expiration warning, can do so from the Tor Project distribution directory.

New PGP subkey
This release is signed using a new subkey. If you previously used GPG to verify Tor Browser downloads, you may need to refresh the Tor Browser signing key (0xEF6E286DDA85EA2A4BA7DE684E2C6E8793298290) in your local keyring. See the signature verification page for details.

Windows Package Signature Issue
The DigiCert EV code‑signing certificate we use to sign Windows installation packages expired on September 1st and we are currently in the process to renew it. This process is delayed and not yet complete. This has caused Windows users trying to install Tor Browser 15.0.21 and 15.0.22 from scratch to receive “bad signature” warnings. As a temporary work‑around, for Windows only we are keeping Tor Browser 15.0.20 (the latest correctly signed version) listed on our download page, relying on automatic updates (which are signed with a different key, not involving this expired certificate) to bring Windows users to the current version. Users who prefer to download the latest version directly, ignoring the certificate expiration warning, can download it from the distribution directory.
