Anti-Sexual Harassment laws.
Family Leave Act (when you have a baby, or when a family member needs care, you can take unpaid leave, and your job will be there when you return -- I used this when my mother had a bypass).
In the 70's, the police routinely ignored domestic violence. There was an infamous case of a woman who had a restraining order against her ex, who had hurt and threatended her repeatedly.
When he showed up, and she called, they took their time, and he stomped her nearly to death, resulting in life-long, severe disability (including paralysis).
She fought to force police to finally take "family disputes" that had serious threat inolved, seriously.
Mostly, the effects have been social, and psychological, rather than legal.
Women have flooded into fields they'd been largely excluded from before: science, medicine, academia, and law among them.
And, though still relatively rare, it's no longer assumed that it's the mother who stays home to care for babies and young children. (A former co-worker of mine fought in court for his job to be available to him, after he took leave to care for his son, while his wife earned the money.)
In general, the notion that women are not some strange, lesser species, has taken hold among most people.
