Allows evidence of a defendant's commission of other enumerated offenses (sexual crimes, child abuse, murder with sexual elements, and formerly rape/deviate sexual assault) to be considered for any matter to which it is relevant if otherwise admissible under evidence rules.

Requires courts weighing probative value against undue prejudice to consider proximity in time, degree of factual similarity, and other relevant facts and circumstances when evaluating such evidence.

Mandates prosecution provide pretrial notice of intent to offer such evidence, including witness statements or testimony summaries, a reasonable time before trial unless good cause excuses advance notice.
