While typesetting a document containing a small tabulated table with the
latest release I noticed that the tabulate \TH command hadn't added any
vertical space between the rows. Here's a mwe.

\starttext
  \starttabulate[|l|l|]
    \NC Γ \NC Gamma \NC\NR
    \NC Θ \NC Theta \NC\NR
    \TB[line]
    \NC Φ \NC Phi \NC\NR
  \stoptabulate
\stoptext
