 Mammath is the python library with all the functions you need to do complicated mathematics, anywhere from 2D and 3D graphing calculators to linear algebra, calculus and even physics. We even have a constant and function for practically everything
 <br>
 
-<h1><b> Release notes 0.2.1 - What's new at 25k downloads</b></h1>
+<h1><b> Release notes 0.3.0 - our biggest release yet</b></h1>
 <ul>
-    <li>Parser implemented with graphing </li>
-    <li>Removed a few unnessecary functions and modules for much faster import and install time</li>
-    <li>Fixed all general functions bugs that we found</li>
-    <li>Added many complex functions</li>
-    <li>Many new maths functions, including more support for 2D list matrices</li>
+    <li>Deprecated old graphing methods, they may be removed in the next release</li>  
+    <li>Methods are all grouped by category. For instance, all calculus functions can be accessed through mammath.calculus, as well as the standard import</li>  
+    <li>Added many new graphs, including the Mandelbrot set (quite spectacular), and other useful plots. The graphing functions have been updated with one function for a function for parametric and Cartesian graphing in 2 and 3 dimensions, as well as complex number functions.</li>  
+    <li>Changed checkers_and_printers to special numbers and refactored the method names to be more intuitive</li>  
+    <li>Added two new tables</li>  
+    <li>Added new sequencing methods (arithmetic sums, geometric sums, etc.)</li>  
+    <li>Created many new physics methods, including time dilation methods, path integrals, and even a photoelectric effect simulator</li>  
+    <li>New linear algebra classes - Vector and Matrix, which each come will useful methods. Methods to compute linear least squares, eigenvalues, and more.</li>  
+    <li>Many new complex functions, including complex hyperbolic methods, the Lambert W function, and the gamma function</li>  
+    <li>New coordinate geometry section. It already has a multitude of features from triangle cevians, special centers, to rotations and harmonic conjguates. We plan to continue expanding this section to a full-on coordinate-based geometry engine with complex geometrical operations</li>  
+    <li>Created many new calculus functions, from integral approximations like the trapezoidal rule, to multivariable calculus (partial derivatives, divergence, and curl). There are also new methods for each calculus function that allow you to visualize the actual function (e.g. derivative calculates the derivative at a point but f_derivative produces a function that can be used to compute, graph, and so much more)</li>
 </ul>
