 new toolchain contains all the same functionality via the built in
 pygame bootstrap.
 
+In the last quarter of 2018 the python recipes has been changed, the new recipe
+for python3 (3.7.1) has a new build system which has been applied to the ancient
+python recipe, allowing us to bump the python2 version number to 2.7.15. This
+change, unifies the build process for both python recipes, and probably solve
+some issues detected over the years, but unfortunately, this change breaks the
+pygame bootstrap (in a near future we will fix it or remove it). Also should be
+mentioned that the old python recipe is still usable, and has been renamed to
+`python2legacy`. This `python2legacy` recipe allow us to build with a minimum
+api lower than 21, which is not the case for the new python recipes which are
+limited to a minimum api of 21. All this work has been done using android ndk
+version r17c, and your build should success with that version...but be aware
+that the project is in constant development so...the ndk version will change
+at some time.
+
+Those mentioned changes has been done this way to make easier the transition
+between python3 and python2. We will slowly phase out python2 support
+towards 2020...so...if you are using python2 in your projects you should
+consider to migrate it into python3.
