+:warning: We had been collecting [the vulnerabilities of QEMU/libslirp](https://www.cvedetails.com/product/57329/Libslirp-Project-Libslirp.html?vendor_id=20192) in this slirp4netns repo until the end of 2020,
+as the slirp4netns releases prior to v1.0.0 were always statically linked with a specific version of QEMU/libslirp.
+Starting with 2021, the vulnerabilities of libslirp are no longer collected in this slirp4netns repo, as slirp4netns >= v1.0.0 can be linked with an arbitrary version of libslirp.
