Wallarm Node — Version 2.8¶
Added the function to block requests from blacklisted IP addresses via NGINX.
Implemented memory consumption ceiling for a single request processing.
Added support for the deflate and brotli compression formats in HTTP responses.
Enhanced monitoring capabilities.
Improved logging mechanism.
