-## NEW
+## FIXED
 
-
-- **1Password Environment access:** The SDK can now read variables from a 1Password Environment.
-
-## IMPROVED
-
-- **Documentation:** The README now covers desktop app authentication and an updated list of supported functionality. Examples print their output, cover vault and group permission operations, and are consistent with the other 1Password SDKs.
-- **Terms of Service:** The README now links the terms of service that apply to the 1Password APIs/SDKs.
+- **Security patch:** On Linux, the SDK now rejects certificate chains that include the eight compromised eMudhra intermediate CA certificates, and no longer bundles the emSign ECC Root CA - G3. Linux users should upgrade, since updating the system CA store alone doesn't remove this trust. On macOS and Windows, certificate checks are handled by the operating system; install the latest OS updates to receive Apple's and Microsoft's distrust of these certificates.
