New features added to freshclam:
- Update signature definitions over HTTPS.
- Support for HTTP protocol v1.1 (formerly v1.0).
- New libfreshclam library with an all new API and versioning separate from libclamav (v2.0.0). This library is now build and installed alongside libclamav as a hard dependency of freshclam.
- The ability to opt-in and opt-out of standard and optional official ClamAV databases (ExtraDatabase, ExcludeDatabase)
- The option to specify the protocol and port number of official and private mirror servers.
- Support for additional types of proxy servers beyond plain HTTP (SOCKS 4, SOCKS 5).
Features removed from freshclam:
- Mirror management (mirrors.dat) file. This feature is no longer needed as official signature databases are distributed using a paid content delivery network (Cloudflare).
This commit also adds the following features for Windows users:
- The clamsubmit tool.
- The json-c library dependency, which will enable the --gen-json option in clamscan.
- Third party libraries under the win32/3rdparty directory have been removed. Developers will need to build the libraries separately from ClamAV and provide the headers and lib/dll library files the same way they do for OpenSSL. This includes libxml2, pthread-win32, bzip2, zlib, pcre2 as well as new dependencies: curl, json-c. Developers are encouraged to use the build tool Mussels to simplify this task.
