Added Symbols (1)

CustomStorage.h, libspatialindex_c.so.3.0.0
namespace SpatialIndex::StorageManager
CustomStorageManager::flush ( )

to the top

Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been increased from 28 bytes to 32 bytes.	1) An object of this class can be allocated by the applications and old size will be hardcoded at the compile time. Call of any exported constructor will break the memory of neighbouring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

CustomStorage.h
namespace SpatialIndex::StorageManager
[+] class CustomStorageManager (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Size of field callbacks has been changed from 24 bytes to 28 bytes.	Size of the inclusive type has been changed.

CustomStorage.h
namespace SpatialIndex::StorageManager
[+] class CustomStorageManager (1)

to the top

Problems with Constants (1)

	Change	Effect
1	The value of constant SIDX_RELEASE_NAME has been changed from "1.7.1" to "1.8.0".	Applications will pass an old value of this constant as the parameter to the new-version library functions, that expect a new one. This may result in crash of incorrect behavior of applications.

Version.h
[+] SIDX_RELEASE_NAME

to the top

Other Changes in Data Types (1)

	Change	Effect
1	Virtual method CustomStorageManager::flush ( ) has been added to this class.	No effect. You can add virtual functions at end of leaf classes with exported constructors.

Offset	Virtual Table (Old) - 7 entries	Virtual Table (New) - 8 entries
0	(int (*)(...))0	(int (*)(...))0
4	(int (*)(...))(& typeinfo)	(int (*)(...))(& typeinfo)
