+2023-06-11 Enrico Forestieri <forenr@lyx.org>
+ * Format incremented to 616: Do not output LaTeX for a macro if the LaTeX part is empty
+ - This allows the user to define the LyX display for LaTeX commands
+ that are already defined (e.g., in user preamble or a package).
+ - No substantive change to file format. Format change just in case someone defined a
+ math macro with an empty LaTeX field. In that case, lyx2lyx adds {} to the LaTeX
+ part on conversion and removes the macro altogether on reversion.
