+------------------------------------------
+0.7.2 (to be announced) "optical friction"
+------------------------------------------
+
+- The sleep subcommand of para_mixer gained two options to control
+ the startup mood and the time period before fade-out starts. A bunch
+ of further improvements for this subcommand went in as well.
+- Minor cleanup of the net subsystem.

--------------------------------------
0.7.1 (2022-10-03) "digital spindrift"
--------------------------------------
requires support from the compiler, the oldest supported gcc version
has been bumped to gcc-5.4 (released in 2015).

+---------------------------------------
+0.5.9 (2021-11-04) "reversed dimension"
+---------------------------------------
+This release contains a few important fixes which have accumulated in
+the maint branch. The paraslash-0.5.x series has now reached its end
+of life and will no longer be supported. All users should upgrade to
+a more recent version at this point.
+
+- Fix an issue with the bash completion script.
+- Initialize the random seed also when using libgrypt.
+- Fix some compiler warnings in the resample filter
+- Don't return spurious errors from the ff server command.
