 thanks to all of these good people here, both for working on the code
 and for prodding me into improving it.
 
+			Changes since 3.0.1rc10
+
+- Potential buffer overflows in minires repaired.
+
+- A change to the linux client script to use /bin/bash, since /bin/sh may
+  not be bash.
+
+- Some missing va_end cleanups thanks to a patch from Thomas Klausner.
+
+- A correction of boolean parsing syntax validation - some illegal syntaxes
+  that worked before are now detected and produce errs, some legal syntaxes
+  that errored before will now work properly.
+
+- Some search-and-replace errors that caused some options to change their
+  names was repaired.
+
+- Shu-min Chang of the Intel corporation has contributed a perl script and
+  module that converts the MS NT4 DHCP configuration to a ISC DHCP3
+  configuration file.
+
+- Applied the remainder of the dhcpctl memory leak patch provided by Bill
+  Squier at ReefEdge, Inc.  (groo@reefedge.com).
+
+- Missing non-optional failover peer configurations will now result in a soft
+  error rather than a null dereference.
+
 			Changes since 3.0.1rc9
 
 - A format string was corrected to fix compiler warnings.
