Problems with Data Types, Medium Severity (1)

	Change	Effect
1	Value of member vbr_default has been changed from 2 to 4.	Applications may execute a wrong branch of code in the library and therefore change the behavior.

Problems with Symbols, Medium Severity (8)

	Change	Effect
1	Type of 1st parameter p1 has been changed from struct lame_version_tconst to struct lame_version_t (became non-const).	This function may change parameter p1, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.

1	Type of 1st parameter gfp has been changed from lame_global_flags constconst to lame_global_flags const (became non-const).	This function may change parameter gfp, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.

	Change	Effect
1	Type of 1st parameter p1 has been changed from *lame_global_flagsconst** to lame_global_flags* (became non-const).	This function may change parameter p1, but it will be treated as const by old client applications. This may result in crash or incorrect behavior of applications.

Problems with Constants (1)

	Change	Effect
1	The value of constant LAME_MAXMP3BUFFER has been changed from 16384 to (16384 + LAME_MAXALBUMART).	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.
