[+] class OutputStream (1)
| Change |
Effect |
| 1 | Pure virtual method OutputStream::WriteUint32Chunk ( uint32_t*, int ) has been added to this class. | 1) Applications will not provide the implementation for this pure virtual method and therefore cause a crash in the library trying to call this method.
2) The layout of v-table has been changed. Call of any virtual method at higher position in this class or its subclasses may result in crash or incorrect behavior of applications. |

| Change | Effect |
|---|
| 1 | Type of 1st parameter change_in_bytes has been changed from int to intptr_t. | Replacement of parameter data type may indicate a change in its semantic meaning. |
