There have been some major developments in Julia package manager in the past year. A system has been added in 1.3 for content-addressed binary artifacts, including data and platform-dependent binaries. In conjunction, the BinaryBuilder system has been updated to produce these artifacts, allowing package to depend on non-Julia libraries without any client-side build step. Pkg 1.4 introduced a new protocol for clients to get packages and artifacts from "Pkg servers" without needing git or GitHub.
This talk will go over the high-level design of the artifact system, how BinaryBuilder lets you easily build binaries for dozens of platforms and get them in the hands of Julia users with unprecedented ease. The bottom line: no client-side build step means no client-side build failures. The new Pkg protocol makes it faster and easier to use the package manager behind a firewall or in countries that don't happen to be close to GitHub's servers. No more libgit2/proxy woes. In Julia 1.5 the Pkg protocol will be the default way that Julia clients get packages and artifacts, making it easier for Julia users everywhere to get packages.
