Problems with Constants (4)

	Change	Effect
1	The value of constant RESTART_MAX_CMD_LINE has been changed from 2048 to 1024.	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.

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 POLICY_AUDIT_SUBCATEGORY_COUNT has been changed from (50) to (53).	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 TRANSACTION_GENERIC_WRITE has been changed from (STANDARD_RIGHTS_WRITE \| TRANSACTION_SET_INFORMATION \| TRANSACTION_COMMIT \| TRANSACTION_ENLIST \| TRANSACTION_ROLLBACK \| TRANSACTION_PROPAGATE \| TRANSACTION_SAVEPOINT \| SYNCHRONIZE) to (STANDARD_RIGHTS_WRITE \| TRANSACTION_SET_INFORMATION \| TRANSACTION_COMMIT \| TRANSACTION_ENLIST \| TRANSACTION_ROLLBACK \| TRANSACTION_PROPAGATE \| SYNCHRONIZE).	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.
