# Bundles

This directory includes the actors bundles for each release. Each actor bundle is a zstd compressed
tarfile containing one bundle per network type. These tarfiles are subsequently embedded in the
lotus binary.

## Updating

To update, run the `./pack.sh` script. For example, the following will pack the [builtin actors release](https://github.com/filecoin-project/builtin-actors/releases) `dev/20220602` into the `v8` tarfile.

```bash
./pack.sh v8 dev/20220602
```

This will:

1. Download the actors bundles and pack them into the appropriate tarfile (`$VERSION.tar.zst`).
2. Run `make bundle-gen` in the top-level directory to regenerate the bundle metadata file for _all_ network versions (all `*.tar.zst` files in this directory).
