<small>Release notes</small></h1>

## Highlights


## Incompatibilities

- Removed SRM and SRM server functionality.
- Removed NIS support

## Acknowledgments

We want to thank Shawn McKee for his contributions.

## Release 12.0.0

### Billing

### Frontend

Update REST API to allow space reservations:

```
 curl -X POST \
      'https://dcache-frontent-endpoint:3881/api/v1/space/tokens?accessLatency=online&retentionPolicy=replica&minSize=8192&description=foobar' \
        -d ''
    {"sizeInBytes":8192,"description":"foobar","id":8}
```
### gPlazma

Removed the NIS plugin as sites are (hopefully) not using it anymore.

### NFS

### Pool

If the pool identifies that the underlying repository operates in READ-ONLY mode, then all running checksum scrubbing processes will be stopped.

### Scripts

Added `dcache pool benchmark` command that executes pre-defined fio benchmark for all pools on the host.

### SRM / SRM Client

The SRM server and SRM client are excluded from the project build and test process.

### Xrootd
