Hello,

I am happy to announce the release of `intPQueue`, a package that offers (two variants of) an efficient priority queue, which is restricted to scenarios where the priorities are low integers. See the [documentation](https://cambium.inria.fr/~fpottier/intPQueue/doc/intPQueue/).

```auto
  opam update && opam install intPQueue

```

Happy queueing,  
François.
