Problems with Data Types, High Severity (2)

	Change	Effect
1	Size of this class has been changed from 8 bytes to 12 bytes.	1) The class has only inline or auto-generated constructors which will be copied to applications at compile time and will allocate an older memory layout. Call of any exported method of this class may access a memory outside the allocated objects or inside the older memory structure and result in crash or incorrect behavior of applications. 2) The memory layout and size of subclasses will be changed.
2	Pure virtual method transaction_impl::start ( ) 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.

Offset	Virtual Table (Old) - 6 entries	Virtual Table (New) - 7 entries
0	(int (*)(...))0	(int (*)(...))0
4	(int (*)(...))(& typeinfo)	(int (*)(...))(& typeinfo)
8	~transaction_impl	~transaction_impl
12	~transaction_impl	~transaction_impl
16	__cxa_pure_virtual	__cxa_pure_virtual

Problems with Symbols, High Severity (4)

	Change	Effect
1	Parameters list has been changed.	The name of the appropriate symbol for this function on binary level has been changed from _ZN3odb20schema_catalog_entryC1EPKcPFbRNS_8databaseEtE to _ZN3odb20schema_catalog_entryC1EPKcPFbRNS_8databaseEtbE. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Field connection_ has been added to this type.	1) This field will not be initialized by old clients. 2) Size of the inclusive type has been changed. NOTE: this field should be accessed only from the new library functions, otherwise it may result in crash or incorrect behavior of applications.
