Problems with Data Types, High Severity (1)

	Change	Effect
1	Size of this class has been increased from 64 bytes to 72 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.

PolarStereographic.hpp
namespace GeographicLib
[+] class PolarStereographic (1)

Problems with Symbols, Medium Severity (1)

	Change	Effect
1	Size of this global data has been changed from 64 bytes to 72 bytes.	Applications will obtain a different value and execution may change.

PolarStereographic.hpp, libGeographic.so.1.1.0
namespace GeographicLib
[+] PolarStereographic::UPS [data] (1)

to the top

Problems with Data Types, Low Severity (1)

	Change	Effect
1	Field _C 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.

PolarStereographic.hpp
namespace GeographicLib
[+] class PolarStereographic (1)

to the top

Problems with Symbols, Low Severity (1)

	Change	Effect
1	The initial value of this global data has been changed from $Id: Constants.hpp 6827 2010-05-20 19:56:18Z karney $ to $Id: Constants.hpp 6842 2010-07-16 20:51:06Z karney $.	Applications will use an old value of this data instead of the new one. This may cause incorrect behavior of applications.

Problems with Constants, Low Severity (6)

	Change	Effect
1	The value of constant GEOGRAPHICLIB_CONSTANTS_HPP has been changed from "$Id: Constants.hpp 6827 2010-05-20 19:56:18Z karney $" to "$Id: Constants.hpp 6842 2010-07-16 20:51:06Z 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_ELLIPTICFUNCTION_HPP has been changed from "$Id: EllipticFunction.hpp 6720 2009-10-17 23:13:57Z ckarney $" to "$Id: EllipticFunction.hpp 6838 2010-06-22 21:26:37Z 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_MGRS_HPP has been changed from "$Id: MGRS.hpp 6785 2010-01-05 22:15:42Z karney $" to "$Id: MGRS.hpp 6843 2010-07-18 21:18:17Z 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 6807 2010-02-01 11:26:34Z karney $" to "$Id: PolarStereographic.hpp 6841 2010-07-11 20:46:32Z 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 6824 2010-04-19 14:25:10Z karney $" to "$Id: TransverseMercator.hpp 6843 2010-07-18 21:18:17Z 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 6824 2010-04-19 14:25:10Z karney $" to "$Id: TransverseMercatorExact.hpp 6835 2010-06-15 21:37:16Z 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.
