====
+---------------------------------------
+0.7.0 (to be announced) "seismic orbit"
+---------------------------------------
+
+- Paraslash writers handle early end-of-file more gracefully.
+- The alsa writer no longer warns about spurious underruns.
+- Cleanups of the doubly linked lists code.
+
+--------------------------------------
+0.6.4 (2021-11-04) "fuzzy calibration"
+--------------------------------------
+
+This point release contains a fair number of fixes but no new features.
+This marks the end of the 0.6 development, although paraslash-0.6 will
+still be supported for some time and subsequent maintenance releases
+may follow.
+
+- The udp sender no longer crashes when empty chunks are encountered.
+- Fix a double-free bug in the exit path of the server.
+- The "jmp" command now errors out when given a negative percentage.
+- A fix for a bug in para_afh which triggered on the attempt to modify
+ the tags of an invalid mp4 file.
+- A memory leak in para_afh has been fixed.
+- The udp sender no longer sends multiple EOF packets.
+- Some gcc warnings have been silenced.
+- Minor log level adjustments and documentation improvements.
+
+Downloads:
+[tarball](./releases/paraslash-0.6.4.tar.xz),

+
+---------------------------------------
+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.
