*** General ***

* Toplevel theorem statements have been simplified as follows:

  theorems             ~>  lemmas
  schematic_lemma      ~>  schematic_goal
  schematic_theorem    ~>  schematic_goal
  schematic_corollary  ~>  schematic_goal

Command-line tool "isabelle update_theorems" updates theory sources
accordingly.

* Toplevel theorem statement 'proposition' is another alias for
'theorem'.


This refers to Isabelle/de610e8df459. Following the principle that we share with the GHC guys "we obsessively refactor while adding new code, keeping the code base as fresh as possible", I have made some cleanups before adding yet another toplevel theorem alias. So the resulting situation is a bit simpler than before.

Internally there is only the one Thm.theoremK tag left over -- and it is actually legacy. See also fa4ebbd350ae.
