 The `develop` branch contains the in-development version. Stable releases are tagged.

 The project can be build by using `make`. Along with the usual `make`, `make clean` and `make install`, there are several other build targets, see the makefile for details. There are also makefiles for certain specific platforms.
 
+## Testing
+
 Tests are located in `demo/` and can be built in two flavors.
 * `make test` creates a test binary that is intended to be run against `mtest`. `mtest` can be built with `make mtest` and test execution is done like `./mtest/mtest | ./test`. `mtest` is creating test vectors using an alternative MPI library and `test` is consuming these vectors to verify correct behavior of ltm
 * `make test_standalone` creates a stand-alone test binary that executes several test routines.

+v1.1.0
+       -- Christoph Zurnieden contributed FIPS 186.4 compliant
+          prime-checking (PR #113), several other fixes and a load of documentation
+       -- Daniel Mendler provided two's-complement functions (PR #124)
+          and mp_{set,get}_double() (PR #123)
+       -- Francois Perrad took care of linting the sources, provided all fixes and
+          a astylerc to auto-format the sources.
+       -- A bunch of patches by Kevin B Kenny have been back-ported from TCL
+       -- Jan Nijtmans provided the patches to `const`ify all API
+          function arguments (also from TCL)
+       -- mp_rand() has now several native random provider implementations
+          and doesn't rely on `rand()` anymore
+       -- Karel Miko provided fixes when building for MS Windows
+          and re-worked the makefile generating process
+       -- The entire environment and build logic has been extended and improved
+          regarding auto-detection of platforms, libtool and a lot more
+       -- Prevent some potential BOF cases
+       -- Improved/fixed mp_lshd() and mp_invmod()
+       -- A load more bugs were fixed by various contributors

-To use the pretty graphs you have to first build/run the ltmtest from the root directory of the package.  
-Todo this type 
-
-make timing ; ltmtest
-
-in the root.  It will run for a while [about ten minutes on most PCs] and produce a series of .log files in logs/.
-
-After doing that run "gnuplot graphs.dem" to make the PNGs.  If you managed todo that all so far just open index.html to view
-them all :-)
-
-Have fun
