-	* CRFsuite 0.4 (the first public release):
-	- Website and documentation for CRFsuite.
-	- Tutorial on the CoNLL 2000 chunking shared task.
-	- Performance comparison on the CoNLL 2000 chunking shared task.
-	- Bug fix in L2 regularization.
-	- A number of small improvements for the public release.
+	* libLBFGS 1.4:
+	- Configurable line search algorithms. A member variable
+	  lbfgs_parameter_t::linesearch was added to choose either MoreThuente
+	  method (LBFGS_LINESEARCH_MORETHUENTE) or backtracking algorithm
+	  (LBFGS_LINESEARCH_BACKTRACKING).
+	- Fixed a bug: the previous version did not compute psuedo-gradients
+	  properly in the line search routines for OW-LQN. This bug might quit
+	  an iteration process too early when the OW-LQN routine was activated
+	  (0 < lbfgs_parameter_t::orthantwise_c).
+	- Configure script for POSIX environments.
+	- SSE/SSE2 optimizations with GCC.
+	- New functions lbfgs_malloc and lbfgs_free to use SSE/SSE2 routines
+	  transparently. It is uncessary to use these functions for libLBFGS
+	  built without SSE/SSE2 routines; you can still use any memory
+	  allocators if SSE/SSE2 routines are disabled in libLBFGS.

-	* CRFsuite 0.3 (internal release):
-	- Implemented scaling method for forward/backward algorithm.
-	- Removed the code for computing the forward/backward algorithm in logarithm domain.
+	* libLBFGS 1.3:
+	- An API change. An argument was added to lbfgs() function to receive
+	  the final value of the objective function. This argument can be set
+	  to NULL if the final value is unnecessary.
+	- Fixed a null-pointer bug in the sample code (reported by Takashi
+	  Imamichi).
+	- Added build scripts for Microsoft Visual Studio 2005 and GCC.
+	- Added README file.

 This library has SSE/SSE2 optimization routines for vector arithmetic

 To use the SSE2 optimization routine, specify --enable-sse2 option to the
 configure script.
