Twitter introduced new notifications options for users.
To start, users will now be able to limit their notifications so they only receive notifications related to users they follow. This setting applies to notifications on both mobile and the web. In addition, mobile users can now manage their notifications settings directly from the notifications tab in the app.

Elsewhere, Twitter is rolling out a “quality filter” option, which will allow users to filter “lower-quality content” from their notifications and “other parts of [their] Twitter experience.” Twitter explained the quality filter in a blog post:
Last year we began testing a quality filter setting and we?re now rolling out a feature for everyone. When turned on, the filter can improve the quality of tweets you see by using a variety of signals, such as account origin and behavior. Turning it on filters lower-quality content, like duplicate tweets or content that appears to be automated, from your notifications and other parts of your Twitter experience. It does not filter content from people you follow or accounts you?ve recently interacted with?and depending on your preferences, you can turn it on or off in your notifications settings.
Twitter said these notifications options will roll out to all use...
