Hi Hans,
Thank you for having fixed the issue with numbered equations in math aligned environment, noticed and reported by Mikael Sundqvist.
However the problem is solved only when the numbers are on the right: when the numbers are on the left, there is still a discrepancy between the location of numbers in equations numbered in an aligned environment and those which are by themselves.
Please have a look at the attached PDF which is the result of the following example (using ConTeXt ver: 2016.09.06 19:11 MKIV beta).
Best regards: OK

Hi Hans,
Following up the previous bug report, I tried the latest version, ConTeXt ver: 2016.09.09 08:21 MKIV beta, and noticed that you have solved one part of the problem with the placement of equation numbers on the left, when using \startalign.
Actually the location of those equation numbers is correct as far as the horizontal distance is concerned, but it is not vertically.
In the attached PDF (which is the result of the following example) one can see that equation number (5) is placed on the grid line 10, while it shoul dbe placed on line 11 in alignment with the corresponding formula. Moreover equation number (4) does not show up at all (that number should be placed a little bit below line 9 of the grid).
Thanks in advance for your time.
Best regards: OK

I think that we need to create a test suite for math alignment. The
sources for my old article on math alignment could be the initial source
of examples.
Unfortunately, these days I mostly use ConTeXt for presentations only (and
use LaTeX for articles). So, my own documents no longer serve as a test
suite for the math features.

fyi: one reason for 'issues' is that i try to simply these alignment
mechanisms so that they can be controlled better for use in framed and
such (local vs page stream usage) and spacing and so .. we'll get there
eventually
