+- 2020/08/25 (0.5) - ImPlotAxisFlags_Scientific was removed. Logarithmic axes automatically uses scientific notation.
 - 2020/08/17 (0.5) - PlotText was changed so that text is centered horizontally and vertically about the desired point.
 - 2020/08/16 (0.5) - An ImPlotContext must be explicitly created and destroyed now with `CreateContext` and `DestroyContext`. Previously, the context was statically initialized in this source file.
 - 2020/06/13 (0.4) - The flags `ImPlotAxisFlag_Adaptive` and `ImPlotFlags_Cull` were removed. Both are now done internally by default.
