 ### Security
 
+- Go version has been updated to prevent the possibility of exploiting the Go vulnerabilities fixed in [1.26.4][go-1.26.4].
+
 - The H2C connection establishment via HTTP/1.1 request upgrade is no longer supported.  See [RFC 9113][rfc9113].

+- The size of rulelists is limited.  This is necessary to prevent a user's machine from becoming overloaded if the filter source misbehaves.
 
 ### Changed
 
+- The interval of filter updates can now be set to any number of ours between 0 and 365 days in the configuration file.
+
 #### Configuration changes
 
 - The `filtering` object of the YAML configuration now includes a new property, `max_http_size`, which defines the maximum size of the HTTP request for rulelists. To disable the limitation, set a large size, such as `1 TB`.
