This version adds in a “Converted from P190” checking option for Px/11 files. This option sets the software version and date in HC,2,1,0 as optional rather than mandatory, as these fields are not in the P190 file and thus cannot be converted across to the Px/11 file.

This version also fixes the checking of the extended fields in the N1 records.

This version updates the checker to allow for a positioning object to be defined in both HC,2,3,0 and H2,5,3,0 records in a P2/11 file.
There is also a user option to control the checking of the “Number of Objects Towed by this Object” totals in the HC,2,3,0 records

This update fixes the checking of the Longitude Axis Abbreviation, which changed in EPSG v8.8

This version updates the software to check the coordinates in the P6/11 position records – the system now checks the M6 record coordinates and the first B6 record.

This version fixes a bug introduced in v1.0.55, where the geodetic checks can give a false error.

This version contains a couple of minor checking updates

• The second coordinate tuple (CRS B) in the M1 Survey Perimeter record is only mandatory for the first set of positions and the check has been updated to allow for this.
• The Event Index number in E2,1,0,1 , T2,3,3,0 and T2,3,3,1 is now set as optional.

This version also updates the inbuilt version of the ESPG database to version 8.8

This update contains a minor change to the geodetic position check changes introduced in v1.0.53, so that the position check takes into account grid positions which are part of a compound reference system.

This update changes the geodetic position checks so that they always convert the geodetic position and check the result against the grid position regardless of the order in which the positions are defined in the file.
