+Corman Lisp 3.1 Release Notes
+December. XX, 2018
+
+It is the first community release intended for real use.
+To see the list of contributors, please, visit the following page:
+https://github.com/sharplispers/cormanlisp/graphs/contributors
+
+The main objectives of this release are:
+* to make the system usable on the modern versions of the Windows operating system, especially the 64-bit ones;
+* to improve the stability of the runtime and kernel code;
+* to improve basic functionality of the IDE;
+* to fix long-standing bugs;
+* to prepare the ground for the future development.
+
+Nevertheless, it contains a lot of new features.
+
+New in this release:
+
+- Support for modern, x64 editions of Windows - it does not crash when intensively using FFI.
+ The application itself is still a 32-bit one.
+
+- New customisable high-quality Lisp code indenting engine in the IDE (Dorai Sitaram's 'scmindent').
+ The functionality is used during source-code editing and is also available via the context menu for reindenting the selected code.
+
+- Hardware-assisted garbage collector mode (experimental, disabled by default).
+ See the new functions ENABLE-HARDWARE-GC and HARDWARE-GC-ENABLED-P (Chapter 12 of the Corman Lisp manual). One can find :HARDWARE-GC keyword in *FEATURES* when this functionality is available (it is always available starting from Corman Lisp 3.1 and onwards).
+
+- Support for multi-user environments.
+ The Corman Lisp does not assume that it has write permissions to the installation directory.
+ See Chapter 6 of the Corman Lisp manual for the additional details.
+
+- User specific initialisation file (%USERPROFILE%\corman-init.lisp).
+
+- Support for high-DPI screens in the IDE.
+
+- Support for IPv6 (when available on the platform).
+One can find :IPV6 keyword in *FEATURES* when this functionality is available.
+
+- Support for datagram sockets.
+One can find :DATAGRAM-SOCKETS keyword in *FEATURES* when this functionality is available.
+
+- Networking sockets library does not need specific initialisation any more.
+ The START-SOCKETS and STOP-SOCKETS are dummy functions which are available for compatibility reasons.
+
+- SSL sockets module does not need any specific initialisation.
+ The START-SSL-SOCKETS is a dummy function which is available only for compatibility reasons.
+
+- SSL sockets module now uses TLS by default.
+
+- New MSI-based installer authored with WiX 3.x.
+
+- Visual Studio 2015 is used to build the project.
+
+- The Visual Studio solution was reorganised to make it easier to build the project and contribute.
+ The only optional dependency is WiX 3.x which is used to build the installer.
+
+- The third party libraries were updated to the latest versions when possible.
+
+- All old Corman Lisp licensing code is properly removed.
+
+- Support for Windows operating system versions older than Windows XP SP3 is dropped.
+
+- It is possible to load a Lisp image without crashing the IDE (all the time ;).
+ Corman Lisp is one of the few modern implementations which provide image loading functionality without restarting the process.
+
+- New LOAD-DEFAULT-IMAGE function.
+ See Chapter 22 of the Corman Lisp manual.
+
+- Numerous improvements to the CLOS implementation.
+
+- Numerous improvements to the kernel and runtime code.
+
+- Numerous bug fixes.
+
+- Numerous stability improvements.
+
+What is missing (planned for the next releases):
+ - Support for the recent version of ASDF.
+ - Support for the new efficient thread synchronisation primitives available starting from Windows Vista and newer.
+
+New examples:
+- Minesweepers AI and GUI demo (examples/minesweepers.lisp).
+
