[+] class UnicodeInputStream (1)
| Change |
Effect |
| 1 | Pure virtual method UnicodeInputStream::PushBack ( int32_t ) 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. |

| 1 | Parameters list has been changed. | The name of the appropriate symbol for this function on binary level has been changed from _ZN2v812HeapProfiler12TakeSnapshotENS_6HandleINS_6StringEEENS_12HeapSnapshot4TypeEPNS_15ActivityControlE to _ZN2v812HeapProfiler12TakeSnapshotENS_6HandleINS_6StringEEENS_12HeapSnapshot4TypeE. This may cause "undefined reference" linker error in old client applications. |
