 Changelog
 -------------
+** 2.0.0 **
+(December 29, 2021) Major update and version change.
+Plugin should now be compatible with latest PHP 8 / MySQL 8.
+Benchmarks no longer comparable between versions. Industry benchmarks will only show results from the same version.
+benchmark script updated to replace deprecated/broken math functions and mysql functions. Version number in benchmark script reflects version number of current open source library it was based on, NOT WPPerformanceTester version number.
+ENCODE() replaced with AES_ENCRYPT to perform mysql benchmark.
+Benchmark graph now uses Chart.js 3.7 instead of 1.x which hopefully helps conflicts with other newer plugins.
 ** 1.1.1 **

+             * Right, this is really confusing and there is a lot of maths going on here
+             * The gist of the problem is here: https://gist.github.com/nnnick/696cc9c55f4b0beb8fe9
+             *
+             * Reaction: https://dl.dropboxusercontent.com/u/34601363/toomuchscience.gif
+             *
+             * Solution:
+             *
+             * We assume the radius of the polygon is half the size of the canvas at first
+             * at each index we check if the text overlaps.
+             *
+             * Where it does, we store that angle and that index.
+             *
+             * After finding the largest index and angle we calculate how much we need to remove
+             * from the shape radius to move the point inwards by that x.
+             *
+             * We average the left and right distances to get the maximum shape radius that can fit in the box
+             * along with labels.
+             *
+             * Once we have that, we can find the centre point for the chart, by taking the x text protrusion
+             * on each side, removing that from the size, halving it and adding the left x protrusion width.
+             *
+             * This will mean we have a shape fitted to the canvas, as large as it can be with the labels
+             * and position it in the most space efficient manner
+             *
+             * https://dl.dropboxusercontent.com/u/34601363/yeahscience.gif

 == Changelog ==
+= 2.0.0 =
+(December 29, 2021) Major update and version change.
+Plugin should now be compatible with latest PHP 8 / MySQL 8.
+Benchmarks no longer comparable between versions. Industry benchmarks will only show results from the same version.
+benchmark script updated to replace deprecated/broken math functions and mysql functions. Version number in benchmark script reflects version number of current open source library it was based on, NOT WPPerformanceTester version number.
+ENCODE() replaced with AES_ENCRYPT to perform mysql benchmark.
+Benchmark graph now uses Chart.js 3.7 instead of 1.x which hopefully helps conflicts with other newer plugins.
