- The program was adapted according to the last changes made in EPSG V7.6 database (November 2010).
- For transformation models from Transformation in steps section, the type of initial and final coordinates was changed. The type of initial and final coordinates can be: Cartesian, Geographic 2D, Geographic 3D, Projection plane 2D or Projection plane 3D. With regards to the former version now you can choose if the initial and final coordinates systems are 2D or 3D (with or without altitude), in the case of the geographical coordinates or projection plane coordinates.

- To ensure a better precision for the Transverse Mercator map projection, calculation formulas were changed with JHS formulas that can be used for a wider range up to ±40º of longitude from the central meridian. USGS formulas previously used were ensuring a centimeter precision for a range of up to ±4º of longitude from the central meridian. Map projections affected by this change: Transverse Mercator, Transverse Mercator (South Orientated), Transverse Mercator Zoned Grid System and Universal Transverse Mercator (UTM).

- Starting from this version the program uses Unicode characters. Also, it is available 64-bit version which has still a lower calculation precision then 32-bit version because 64-bit Windows reserves 64 bites for real numbers (15 - 16 significant numbers) and 32-bit Windows reserves 80 bites for real numbers (19 - 20 significant numbers).
- Section Steps transformations becomes General transformations and transformation steps of a transformation model are called now coordinate operations.

- The data introduced in tables are retained as unformatted text. When entering the cell for editing the text is displayed unformatted and at exiting from cell is displayed formatted according to the decimal number set in options. By retaining these unformatted texts in tables coordinate transformations can be made without altering calculation precision for reverse transformations.
- Button for reverse transformation was added for all sections with coordinate transformations. This button is active only for transformations where this action is possible.

- Button to calculate parameters for reverse transformation was introduced for all boxes with 1D, 2D or 3D transformation parameters. It is active only for transformations that supports this calculation. Still, there are cases where reverse transformation calculation can be applied but the calculation of the parameters for reverse transformation is not possible.
- Buttons inside 2D Buttons inside 2D and 3D preview windows disappear when are not used and appear again when positioning mouse over them.
- For 3D preview there were introduced automatic localization and focusing of points displayed.
- A new functionality regarding quick drawing of a polygon in Google Earth using coordinates from projection system was introduced. This command is useful for individuals that are not specialists in geodesy such as real estate agents, banking officials, land owners and so on and can be used to draw parcels that have coordinates in projection system (cadastre coordinates).
- In this version you can do modifications for transformation models from all opened windows of the program but saving is made for the last opened window. To avoid the lost of some transformation models program issues a warning message when closing the main program window.

- Model can be inverted for reversible transformation models.
- The model validation test was introduced both in contextual menu and at the calculation of coordinates that uses transformation models. The test checks the correctness of coordinate systems stringing through all coordinate operations.
- The transformations from a system to another, at the transformation test for one point, can be made in four ways, such as: from system A to B and again to B, from A to B, from B to A and from B to A and again to B. In the cases where the test is used forwardly-backwardly too it is also shown the calculated difference between the coordinates from the system from which the transformation started and the coordinates calculated through forward-backward transformation.
- All the models from the list can be saved in a file. Also, files containing one or more models can be loaded into the list,
*mtrs*extension files. - The information whether the model is reversible or not is also shown at the preview of model properties that are loaded from internet database.
- The obligation to introduce a test point at the publishing of a transformation model in the internet database was eliminated. It was introduced the possibility to add or not maximum 10 points calculated with the transformation model.

- There can be introduced both method name and EPSG code at the properties of coordinates operation. Also, the information about the operation with coordinates from EPSG database can be viewed according to introduced code.
- It was introduced the possibility to introduce parameters for reverse calculation too at Parameters transformation section for the transformations that are not reversible.

- It was introduced the possibility to select only operations like "General Offsets" translation at filtering when choosing a coordinate operation from EPSG database.
- It was introduced the possibility to filter by the method code too when searching coordinate operations or CRS-es in EPSG database.
- The information about source and destination CRS-es can be shown in a window at the description of an operation with coordinates from EPSG database.
- When searching the routes between the CRS-es from EPSG database if the same coordinate operations are found that have different versions it is taken as initial selected operation the one with the bigger version.

- Reading error of some angles expressed in sexagesimal (DMS) from EPSG database.
- Eliminating calculation error for projections having EPSG method codes:

- Lambert Conformal Conic (2SP) - EPSG method code 9802;

- Lambert Conformal Conic (2SP) Belgium - EPSG method code 9803.

- Molodensky-Badekas (PV geocentric domain) - EPSG method code 1061;

- Molodensky-Badekas (PV geog3D domain) - EPSG method code 1062;

- Molodensky-Badekas (PV geog2D domain) - EPSG method code 1063.

- When defining an operation with coordinates, it is now possible to establish if the elevation calculated by it is the final elevation of the transformation model and if in the calculation of the operation with coordinates the elevation is retrieved from the coordinates of the initial system. With these two settings, the model can be used as a two-way calculation: height is calculated on one of the ways and the coordinates from the 2D domain on the other way.
- The program was adapted according to the last changes made in the EPSG V8.7 database (2015, April).
