+One of my lead developers mentioned that they had sent a bug to you about
+ the annotations feature of MatPlotLib.
+ Would you be able to let me know what the timeline is to resolve that bug?
+ The reason is that
+\series bold
+\color red
+the feature is needed for the Phoenix project and their arrival at Mars
+ will be in March sometime
+\series default
+\color inherit
+, but they are doing their testing in the coming few months.
+ This annotation feature is used on reports that present the analysis of
+ the trajectory to the navigation team and it shows up on our schedule.

+B-plane plots are used to show the trajectory of a spacecraft with respect
+ to the target body (specifically perpendicular to the incoming asymptote

+ The plot is used heavily in flight operations so it is important to our

+In addition, we have what is called a thundering heard plot where many different

+ The annotations are import there so we can see which plot corresponds to

+ I hope it helps to know how your code will be used in spacecraft navigation.
