+## [2.5.2] - 2022-09-04
+
+Hi everyone!
+
+We have a new VOLK release! We are happy to announce VOLK v2.5.2! We want to thank all contributors. This release wouldn't have been possible without them.
+
+We are happy to announce that our re-licensing effort is complete. This has been a long and challenging journey. Being technical: There are 3 people left (out of 74) who we haven't been able to get in contact with (at all), for a total of 4 (out of 1092) commits, 13 (of 282822) additions, and 7 (of 170421) deletions. We have reviewed these commits and all are simple changes (e.g., 1 line change) and most are no longer relevant (e.g., to a file that no longer exists). VOLK maintainers are in agreement that the combination -- small numbers of changes per committer, simple changes per commit, commits no longer relevant -- means that we can proceed with re-licensing without the approval of the folks. We will try reaching out periodically to these folks, but we believe it unlikely we will get a reply.
+
+This maintainance release is intended to be the last VOLK 2.x release. After we completed our re-licensing effort, we want to make a VOLK 3.0 release soon. VOLK 3.0 will be fully compatible with VOLK 2.x on a technical level. However, VOLK 3+ will be released under LGPL. We are convinced a license change justifies a major release.
