1- V1.00 -> V2.00

Evolutions made are:

Remark:
All these modifications do that it is not possible to restore with V2.00
version files created with V1.00 version (and reciprocally).


2- V2.00 -> V2.10

Evolutions made are:

Remark:
All these modifications do not concern file format. So it is possible to use files created with version 2.00 (and version 2.00 can use file created with version 2.10).


3- V2.10 -> V2.20

Evolutions made are:

Remark:
This version is able to restore files created with previous versions (V2.00 and V2.10).
If all sectors of a partition are saved, created file format is not modified, so file can be restored with previous version program (V2.00 and V2.10).
If only occupied sectors are saved, it is not possible to use this file with previous version of program (you will get an "Bad compression format" error).


4- V2.20 -> V2.21

Evolutions made are:


5- V2.21 -> V2.22

Evolutions made are:

Remark:
Evolutions made on hard disks detection for 2.21 and 2.22 versions can in some case do that an hard disk is not the same has the one in the saved file if this one has been created with a version preceding the 2.21 one. If only occupied sectors have been saved, this does not have any consequence, but in the case where all sectors have been saved, it can generate an "No partition agrees with one saved into file" error. In this case you have to use the version you have used to create the file.


6- V2.22 -> V2.30

Evolutions made are:

Remark:
This version is able to restore files created with previous versions. Reverse is true also, but not in case where only occupied sectors of NTFS partition were saved (using a previous version on such a file will return a "Bad filesystem format" error when opening file).


7- V2.30 -> V2.40

Evolutions made are:

Remark:
This version is able to restore files created with previous versions. Reverse is true also. Nevertheless, if you have got some bad sectors when saving only occupied sectors of FAT partition, it is better to do this saving again with this version (as long as you do not change disk, previous saving will work, but the day you change your disk, it is possible that it does not work any more).


8- V2.40 -> V2.50

Evolutions made are:

Remark:
This version is able to restore files created with previous versions. Reverse is true also.


9- V2.50 -> V2.60

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also, but not in case of saving disk, MBR, first sectors of disk or partition table (using a previous version on such a file will return a "Bad filesystem format" error when opening file). When disk use a standard access method, it can also occurs that files created with this version cannot be restored with a previous version.


10- V2.60 -> V2.70

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also, but not in case of saving floppy disk or DOS device (using a previous version on such a file will return a "Bad support type" error when opening file).


11- V2.70 -> V2.80

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.
Because of the first correction, restoring partition can appear as different as origin one even if it is the same. In this case and if you have saved all sectors (and so no partition will match), you will be obliged to use the same version as the one you use for saving. If you have saved only occupied sectors, there will be theoretically no differences.


12- V2.80 -> V2.90

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.
Because of adding environment variable use into option file, if an old option file has a '%' into an option, it can be incorrectly read (you have to double the '%' to get it working).


13- V2.90 -> V2.91

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also. But in case of very fragmented NTFS partition, it is obvious that previous version will not be able to restore file created with this version. It is also to be noticed that you can get a little difference on file size between this version and previous one when saving NTFS partition, this is not a problem and does not disallow file compatibility.


14- V2.91 -> V3.00

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also but not for partitions that were saved on themselves or without swap files. Restoring a FAT partition that was saved on itself by a previous version does not enable the automatic check, so you will have to perform it by yourself.


15- V3.00 -> V3.01

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


16- V3.01 -> V3.10

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also but not for ext2 partitions that were saved on themselves.


17- V3.10 -> V3.11

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


18- V3.11 -> V3.20

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


19- V3.20 -> V3.30

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


20- V3.30 -> V3.40

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


21- V3.40 -> V3.50

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


22- V3.50 -> V3.60

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


23- V3.60 -> V3.70

Evolutions made are:

Remarks:


24- V3.70 -> V3.71

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


25- V3.71 -> V3.80

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true for backup of partitions where all sectors were saved, but previous versions cannot restore backup created with this version for partitions where only occupied sectors are saved because of change to improve restoration estimation time.


26- V3.80 -> V3.90

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also, less for backup of GUID partitions table.


27- V3.90 -> V4.00

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also, less for backup of raw files.


28- V4.00 -> V4.10

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


29- V4.10 -> V4.20

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also.


30- V4.20 -> V4.30

Evolutions made are:

Remark:
This version can restore files created with previous versions. Reverse is true also less for backup of ext4 partitions using newly supported features.
