At FOSDEM 2020 we presented the first version of Alire, the package manager for the Ada Open Source ecosystem. Two years later, the tools and its ecosystem have evolved, in some instances based on the feedback received at FOSDEM. So we want to give you an update on the new features and improvements, including:

• Pin system: intended to help with the development and use of WIP crates.
• Crate configuration: that enables static code generation before compilation.
• Toolchains: that enable easy installation of [cross-]compiler and builder versions.
• Auto GPR with: for automatic “with”ing of dependencies.
• Etc.

We will also have a look at the ecosystem of crates available in the Alire community index.
