[VOLK] Release 2.5.2

[Johannes Demel]

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.

to numerous to list in in an email, but that's why we've got a Changelog. Compare what 
happened between 3.9.5.0 and 3.10.2.0 in [1] and what happened between 3.9.5.0 and 3.9.6.0 
in [2].



2. When you did build of the latest GNURADIO version , what UHD version did you 
use?


A lot of people build GNU Radio, so this has many answers. Anyway, the minimum version of 
UHD is 3.9.7; that and any later version works.
Note that, as for any other library, the version of the library you used when building 
needs to be the same as for running.


Best,
Marcus

1. What are the differences between those GNURADIO versions:

3.10.2.0

And

3.9.6.0

2. When you did build of the latest GNURADIO version , what UHD version did
you use?

Thanks,
