Problems with Data Types, High Severity (2)

	Change	Effect
1	Size of this class has been changed from 20 bytes to 16 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.

Problems with Symbols, High Severity (8)

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase13extraIncludesERK7QString to _ZNK12TypeDatabase13extraIncludesERK7QString. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase17findContainerTypeERK7QString to _ZNK12TypeDatabase17findContainerTypeERK7QString. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase27findTargetLangPrimitiveTypeERK7QString to _ZNK12TypeDatabase27findTargetLangPrimitiveTypeERK7QString. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase15isClassRejectedERK7QString to _ZNK12TypeDatabase15isClassRejectedERK7QString. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase14isEnumRejectedERK7QStringS2_ to _ZNK12TypeDatabase14isEnumRejectedERK7QStringS2_. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase15isFieldRejectedERK7QStringS2_ to _ZNK12TypeDatabase15isFieldRejectedERK7QStringS2_. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase18isFunctionRejectedERK7QStringS2_ to _ZNK12TypeDatabase18isFunctionRejectedERK7QStringS2_. This may cause "undefined reference" linker error in old client applications.

	Change	Effect
1	Method became const.	The name of the appropriate symbol for this function on binary level has been changed from _ZN12TypeDatabase26modifiedTypesystemFilepathERK7QString to _ZNK12TypeDatabase26modifiedTypesystemFilepathERK7QString. This may cause "undefined reference" linker error in old client applications.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Size of this type has been changed from 36 bytes to 32 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Size of this type has been changed from 48 bytes to 44 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.

	Change	Effect
1	Field name has been renamed to m_name.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.
2	Field type has been renamed to m_type.	Renaming of a field in data type may indicate a change in the semantic meaning of the field.
