Calendar Grey January 8, 2026
Dist Fedora Esm H88
Explore critical updates for Fedora 43 wget2 version 2.2.1 addressing memory corruption and file write issues.
New version 2.2.1

Summary

GNU Wget2 is the successor of GNU Wget, a file and recursive website

downloader.

Designed and written from scratch it wraps around libwget, that provides the

basic functions needed by a web client.

Wget2 works multi-threaded and uses many features to allow fast operation.

In many cases Wget2 downloads much faster than Wget1.x due to HTTP2, HTTP

compression, parallel connections and use of If-Modified-Since HTTP header.
