I am happy to announce [`AstroFITS`](https://github.com/emmt/AstroFITS.jl), a new official package (formerly [`EasyFITS`](https://github.com/emmt/EasyFITS.jl)) for easy access to FITS files widely used in astronomy to store data.

The ideas leading to [`AstroFITS`](https://github.com/emmt/AstroFITS.jl) were to be produce code that makes clear the structure of written FITS files and to improve type-stability of methods reading the content of FITS files. For examples, you may have a look at the [`README.md`](https://github.com/emmt/AstroFITS.jl/blob/main/README.md) file or at the [documentation](https://emmt.github.io/AstroFITS.jl/stable/).

For those using [`EasyFITS`](https://github.com/emmt/EasyFITS.jl), the only required changes in your code are:

- replace all occurences of `EasyFITS` by `AstroFITS` in your code (and fix [deprecations](https://github.com/emmt/EasyFITS.jl/blob/v0.7.3/src/deprecated.jl) if any);

- in your `Project.toml` files, replace all occurrences of `EasyFITS` by `AstroFITS` with its new UUID and version:

The name change was needed to avoid ambiguities in package names.

There is also the pure Julia FITS files package FITSFiles.jl with a user interface similar to my original PyFITS (now astropy.io.fits) of 25 years ago.
