Problems with Data Types, Low Severity (2)

	Change	Effect
1	Size of this type has been changed from 2048 bytes to 2056 bytes.	The fields or parameters of such data type may be incorrectly initialized or accessed by old client applications.
2	Base type has been changed from struct _keymap_entry[256] to struct _keymap_entry[257].	Replacement of the base data type may indicate a change in its semantic meaning.

keymaps.h
[+] typedef KEYMAP_ENTRY_ARRAY (2)

Problems with Constants, Low Severity (1)

	Change	Effect
1	The value of constant KEYMAP_SIZE has been changed from 256 to 257.	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.

keymaps.h
[+] KEYMAP_SIZE

Other Changes in Constants (1)

	Change	Effect
1	The constant ANYOTHERKEY with value KEYMAP_SIZE-1 has been added.	No effect.
