The FOAM file format has not changed from version 2.0 in many years and so there
is no longer a need for the 'version' entry in the FoamFile header to be
required and to reduce unnecessary clutter it is now optional, defaulting to the
current file format 2.0.

If the combination of chemistry model and solver selected in chemistryProperties
is not already compiled and present in the standard libraries for the selected
thermophysical properties the chemistry package will be constructed and compiled
automatically using the standard dynamicCode system provided in OpenFOAM.
The chemistry package is constructed automatically from the
etc/codeTemplates/dynamicCode/basicChemistryModel.* files, if these files do not
exist the standard chemistry lookup error message is generated as before.
As with all other dynamicCode options in OpenFOAM (codeStream,
codedFunctionObject etc.) dynamic compilation of the chemistry package is only
enabled if allowSystemOperations is set true.
