| 3 | The relative position of field zero2 has been changed from 4 to 2. | Applications will access incorrect memory when attempting to access this field. |
| Change | Effect | |
|---|---|---|
| 1 | Size of field unknown1 has been changed from 2 bits to 1 bit. | Previous accesses of applications and library functions to this field may be broken. |
| Change | Effect | |
|---|---|---|
| 1 | The relative position of field auto_action_mode has been changed from 7 to 9. | Applications will access incorrect memory when attempting to access this field. |
| 2 | The relative position of field up has been changed from 8 to 4. | Applications will access incorrect memory when attempting to access this field. |
| 3 | The relative position of field y_end has been changed from 4 to 6. | Applications will access incorrect memory when attempting to access this field. |
| 4 | The relative position of field y_start has been changed from 6 to 8. | Applications will access incorrect memory when attempting to access this field. |
| 5 | The relative position of field zero2 has been changed from 5 to 7. | Applications will access incorrect memory when attempting to access this field. |
| 6 | The relative position of field zero3 has been changed from 9 to 5. | Applications will access incorrect memory when attempting to access this field. |
| Change | Effect | |
|---|---|---|
| 1 | Field app_info has been added to this type. | This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications. |
| 2 | Field code_extension has been added to this type. | This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications. |
| 3 | Field unknown3 has been added to this type. | This field will not be initialized by old clients. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications. |
| Change | Effect | |
|---|---|---|
| 1 | Field unknown1 has been renamed to playback_mode. | Renaming of a field in data type may indicate a change in the semantic meaning of the field. |
| Change | Effect | |
|---|---|---|
| 1 | Base type of field vts_tmapt has been changed from int (4 bytes) to struct vts_tmapt_t (16 bytes). | Possible access of applications to incorrect memory through the pointer. |
