+NEWS for Mercury 22.01.8
+========================
+
+This is a bug-fix release.
+
+* [Mantis bug #565]. We have reverted a change that broke `mmake` in Mercury
+  versions 22.01.6 and 22.01.7.
+
+* We have fixed a problem that was causing the generation of the debugger
+  documentation to fail on Cygwin.
+
+* We have increased the C stack size for the compiler on 64-bit Cygwin
+  systems, due to stack overflows occuring with the default size.
+
+* We have fixed a bug in the debugger where the output of the command `print *`
+  could be written to an incorrect stream.
