Changelog
--preamble(-p) options to prepend static text to Websocat sessions. For use to authenticate and subscribe to something over WebSocket. Note that specifying passwords on command line may be insecure. Also command line handling around-pis finicky. There is also--preamble-reverse(-P) option to prepend similar chunk in the reverse direction.--compress-{zlib,deflate,gzip}and respective--uncompress-...options to modify binary WebSocket messages going to/from a WebSocket. Note that it is not related to permessage-deflate, which does similar thing, but on lower level.exit_on_specific_byte:overlay to trigger exit when specific byte is encountered. For interactive tty usage.--client-pkcs12-derto specify client identity certificate for connecting towss://orssl:that requires mutual authentication.openssl-probeis now active by default on Linux, to support for overriding CA lists using environment variables.- Incoming WebSocket frames and message are now limited by default, to prevent memory stuffing denial of service. But the default limit is big (100 megabytes). Use
--max-ws-frame-lengthand--max-ws-message-lengthoptions to override. Cargo.lockis now oriented for building with modern Rust compiler. There isCargo.lock.legacywith dependencies manually locked to versions that support Rust 1.46.0.
