Hans,
this sample:
\showgrid
\setupbodyfont[30pt]
\starttext
{\tfa\setupinterlinespace \ConTeXt\par}\\
{\tfxx\setupinterlinespace Author\par}\\
{\tfxx\setupinterlinespace\currentdate\par}\\
{\tf\setupinterlinespace url\par}
\stoptext
With either latest beta or beta from 2015.03.25 22:13, last line in the
sample is on grid line number 3.
With stable beta from TL14 (2014.05.21 22:04), last line from sample is
after grid line 6.
I’m afraid it might be a bug.
Many thanks for your help,
Pablo

hm, more likely a fix (prevdepth or so)

Many thanks for your help, Hans.
I have seen strut in the past, but I’m afraid that I don’t know what it
may be or what I can use it for (besides your sample).
Many thanks for your help,
Pablo

tex has no built-in concept of lineheight and depth only of distance
so, if you want consistency you need to make sure the first line has
height and the last line depth
for normal running text this goes ok (thanks to baselineskip being the
sum of wanted height and depth)
but ... as soon as you start boxing you need to make sure you enforce
the proper ht and dp is needed
\begstrut ... \endstrut
can be used for that
most mechanisnm in context deal with this themselves (for instance
framed and tables .. tables would look horrible otherwise)
(try \showstruts before \starttext so see where \struts are used)
