+Changes since version 1.6.0-rc1
+~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+
+ * Change LUKS default cipher to to use XTS encryption mode,
+   aes-xts-plain64 (i.e. using AES128-XTS).
+
+   XTS mode becomes standard in hard disk encryption.
+
+   You can still use any old mode:
+    - compile cryptsetup with old default:
+      configure --with-luks1-cipher=aes --with-luks1-mode=cbc-essiv:sha256 --with-luks1-keybits=256
+    - format LUKS device with old default:
+      cryptsetup luksFormat -c aes-cbc-essiv:sha256 -s 256 <device>
+
+
+ * Skip tests and fix error messages if running on old systems (or with old kernel).
+
+ * Rename configure.in to configure.ac and fix issues with new automake and pkgconfig
+   and --disable-kernel_crypto option to allow compilation with old kernel headers.
+
+ * Allow repair of 512 bits key header.
+
+ * Fix status of device if path argument is used and fix double path prefix
+   for non-existent device path.
