 Priority:  Normal                |  Milestone:
Component:  ports                 |    Version:  2.3.4
 Keywords:                        |       Port:  zstd
----------------------------------+--------------------------------
 The current zstd port with version 0.8.1 now has the wrong hash, probably
 related to moving the github repo to https://github.com/facebook/zstd

 But as v1.0.0 was released the port should be updated.
