beta release , a completely redesigned version of the program for automating recursive content downloads . GNU Wget 2 has been designed and rewritten from scratch and is notable for moving the core functionality of the web client into the libwget library, which can be used separately in applications. The utility is provided under the GPLv3+ license, while the library is under LGPLv3+.
Wget 2 has transitioned to a multi-threaded architecture, supports HTTP/2, zstd compression, request parallelization, and considers the HTTP header If-Modified-Since, which allows for a significant increase in download speed compared to the Wget 1.x branch. Other features of the new version include support for the OCSP (Online Certificate Status Protocol), TLS 1.3, TCP FastOpen for expedited TCP connection setup, and the ability to use GnuTLS, WolfSSL, and OpenSSL as backends for TLS.
