Make the items in the changelog a bit clearer, reformat it a bit.

ChangeLog

 2010-10-22 Theano 0.3
-	* This is in important release since 0.1. Their have been a 0.2 started internally that was never advertised.
-	* Their is so much change that we lost trac of many of them. Here is some of them.
+---------------------
 
-	* Gpu code with cuda are now generated for many op
-	* Some interface change since 0.1
-		* New SharedVariable system to allow reusing memory space between theano function.
-			* A new memory contract have been done for Theano for people that want to minimize memory copy.
-		* We Deprecate the old Module system
-		* No silent downcast of a theano function input by default.
-		* Raise an error when using the result of logical operation on Theano varible in if (call to __nonzeros__)
-		* Raise an error when we receive not aligned ndarray.(this is not supported)
-		* Raise an error when DimShuffle receive bad configuration number.
-		* Call numpy blas binding for gemv (We already linked with blas gemm)
-		* If gcc is not enable by default fall back to the python version with a warning.
-		* Raise an error when tensor.grad is called on a non scalar theano variable
-			* In the past we where implecitly doing a sum on the tensor to make it a scalar
-		* added erf and erfc fct.
-	* Deprecate the current default value of the paramter axis of theano.{max,min,argmax,argmin,max_and_argmax}. We will use the same interface as numpy
-	* make easy_install theano work
+This is the first major release of Theano since 0.1. Version 0.2 development
+started internally but it was never advertised as a release.
 
+There have been so many changes since 0.1 that we have lost track of many of
+them. Below is a *partial* list of changes since 0.1.
+
+ * GPU code using NVIDIA's CUDA framework is no now generated for many Ops.
+ * Some interface changes since 0.1:
+     * A new "shared variable" system to allow reusing memory space between
+       Theano functions.
+         * A new memory contract has been formally written for Theano,
+           for people that want to minimize memory copies.
+     * The old module system has been deprecated.
+     * By default, inputs to a Theano function will not be silently
+       downcast (e.g. from float64 to float32).
+     * An error is now raised when using the result of logical operation on
+       Theano variable in an 'if' (i.e. an implicit call to __nonzeros__)
+     * An error is now raised when we receive a non-aligned ndarray as
+       input to a function (this is not supported).
+     * An error is raised when the list of dimensions passed to
+       dimshuffle() contains duplicates or is otherwise not sensible.
+     * Call NumPy BLAS bindings for gemv operations in addition to the
+       already supported gemm.
+     * If gcc is unavailable at import time, Theano now falls back to a
+       Python-based emulation mode after raising a warning.
+     * An error is now raised when tensor.grad is called on a non-scalar
+       Theano variable (in the past we would implicitly do a sum on the
+       tensor to make it a scalar).
+     * Added support for "erf" and "erfc" functions.
+ * The current default value of the parameter axis of theano.{max,min,
+   argmax,argmin,max_and_argmax} is deprecated, with the NumPy defaults
+   (operation over the entire tensor) instead.
+ * Theano is now available from PyPI and installable by "easy_install" or
+   "pip" tools.
