Release 1.90.8

It seems that GLib may process multiple DBus signals in one mainloop
iteration. This could cause messages to be re-ordered, which in turn
caused a race condition in the CI that could trigger random failures.

 This file lists notable changes in each release. For the full history of all
 changes, see ChangeLog.
 
+Version 1.90.8:
+
+It seems that we are finally reaching the end of the tunnel with regard
+to regressions. One more issue that cropped up was that a pam_fprintd fix
+to avoid a possible authentication bypass caused issues when fprintd was
+just started on demand.
+
+Highlights:
+ - pam: Only listen to NameOwnerChanged after fprintd is known to run (#94)
+ - Place new ObjectManager DBus API at /net/reactivated/Fprint
+
+
+Version 1.90.7:
+
+While 1.90.6 fixed a number of issues, we did have a bad regression due
+causing pam_fprintd to crash when there are no fingerprint devices
+installed.
+
+Highlights:
+ - pam: Guard strdup calls against NULL pointers
+
+
 Version 1.90.6:
 
 The 1.90.5 release was unusable due to a number of inter-related issues
