Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been increased from 184 bytes to 200 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 neighboring objects on the stack or heap. 2) The memory layout and size of subclasses will be changed.

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Size of this global data has been changed from 184 bytes to 200 bytes.	Applications will obtain a different value and execution may change.

Problems with Data Types, Low Severity (4)

	Change	Effect
1	Field _alp has been added to this type.	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.
2	Field _bet has been added to this type.	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.
3	Field _h has been removed from this type.	Size of the inclusive type has been changed.
4	Field _hp has been removed from this type.	Size of the inclusive type has been changed.

Problems with Symbols, Low Severity (1)

	Change	Effect
1	The initial value of this global data has been changed from $Id: Constants.hpp 6785 2010-01-05 22:15:42Z karney $ to $Id: Constants.hpp 6817 2010-02-08 14:42:35Z karney $.	Applications will use an old value of this data instead of the new one. This may cause incorrect behavior of applications.

to the top

Problems with Constants, Low Severity (6)

	Change	Effect
1	The value of constant GEOGRAPHICLIB_CONSTANTS_HPP has been changed from "$Id: Constants.hpp 6785 2010-01-05 22:15:42Z karney $" to "$Id: Constants.hpp 6817 2010-02-08 14:42:35Z karney $".	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.

	Change	Effect
1	The value of constant GEOGRAPHICLIB_LAMBERTCONFORMALCONIC_HPP has been changed from "$Id: LambertConformalConic.hpp 6720 2009-10-17 23:13:57Z ckarney $" to "$Id: LambertConformalConic.hpp 6816 2010-02-05 21:03:10Z karney $".	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.

	Change	Effect
1	The value of constant GEOGRAPHICLIB_POLARSTEREOGRAPHIC_HPP has been changed from "$Id: PolarStereographic.hpp 6785 2010-01-05 22:15:42Z karney $" to "$Id: PolarStereographic.hpp 6807 2010-02-01 11:26:34Z karney $".	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.

	Change	Effect
1	The value of constant GEOGRAPHICLIB_TRANSVERSEMERCATOR_HPP has been changed from "$Id: TransverseMercator.hpp 6785 2010-01-05 22:15:42Z karney $" to "$Id: TransverseMercator.hpp 6807 2010-02-01 11:26:34Z karney $".	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.

	Change	Effect
1	The value of constant GEOGRAPHICLIB_TRANSVERSEMERCATOREXACT_HPP has been changed from "$Id: TransverseMercatorExact.hpp 6785 2010-01-05 22:15:42Z karney $" to "$Id: TransverseMercatorExact.hpp 6807 2010-02-01 11:26:34Z karney $".	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.

	Change	Effect
1	The value of constant GEOGRAPHICLIB_UTMUPS_HPP has been changed from "$Id: UTMUPS.hpp 6785 2010-01-05 22:15:42Z karney $" to "$Id: UTMUPS.hpp 6805 2010-01-28 21:18:14Z karney $".	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.
