Heads up: ignore samtools dot org, similarly minimap2 dot com and likely others. It's owned by a known phishing site and while the binaries they offer look valid currently (but note they may be serving us different binaries to others), that could change. Ie: it's not us (Samtools team)! Be warned

It's taken more than 2 years but we can officially announce anndataR! There's still a lot of features to add but we hope a robust, "official", R-native H5AD reader/writer will unlock the defacto single-cell storage format for R users by avoiding issues with current solutions like zellkonverter.
