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.

 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
+with the DBus interface and authorization. We also found a number of
+problems with possible security implications.
+
+Currently fprintd will do interactive authorization even if this was not
+requested using the correct DBus method call flag. All API users MUST be
+updated to set the flag as it will be enabled in the future!
+
+Highlights:
+ - Fix fprintd DBus configuration
+ - Change details of what requires authorization
+ - Fix various race conditions in pam_fprintd
+ - Permit interactive authorization from fprintd utilities
+ - Do not allow deletion while another operation is ongoing
+
+
+Version 1.90.5:
+
+The 1.90.4 release contained some bad errors, this release addresses those.
+
+Highlights:
+ - Permit building with polkit older than 0.114
+ - Fix possible issues with PAM test
+ - Fix incorrect DBus policy
+ - Fix build so that CFLAGS enviroment is correctly used
+ - Skip hotplug test with older libfprint (which times out otherwise)
+
 Version 1.90.4:
 
 This fprintd release contains major core reworkings and improved testing.
