The venerable [ERFA.jl](https://github.com/JuliaAstro/ERFA.jl) has reached version 1.0 🎉

For those who have not heard about it, yet, it is a Julia wrapper for [liberfa](https://github.com/liberfa/erfa) which in turn is the open-source version of the [Standards of Fundamental Astronomy (SOFA)](https://www.iausofa.org/) by the International Astronomical Union (IAU).

**TL;DR:** Lots of very useful and standardised algorithms and procedures for astronomy and other astro\* stuff.

After Mike Nolta (@nolta) started the package in 2014, ERFA.jl had quite a few different maintainers (including Nirina R., @kbarbary, @giordano) and I want to thank them for getting us this far 🎉

ERFA.jl is an essential part of my validation workflow for developing new pure-Julia package such as [AstroBase.jl](https://github.com/JuliaAstro/AstroBase.jl).

I have registered two new versions:

- v1.0 which is based on liberfa 1.7.3 and compatible with Julia 1.3+
- v1.1 which is based on liberfa 2.0.0 and compatible with Julia 1.6+
