This is the best summary I could come up with:

Meta is rolling out end-to-end encryption for one-on-one chats and calls on Messenger, finally fulfilling a promise that’s been in the works for quite awhile.

“Our engineers, cryptographers, designers, policy experts and product managers have worked tirelessly to rebuild Messenger features from the ground up.”

According to Crisan, you won’t sacrifice Messenger features when using encrypted chats, so you’ll still be able to use things like themes and custom reactions.

“I believe the future of communication will increasingly shift to private, encrypted services where people can be confident what they say to each other stays secure and their messages and content won’t stick around forever,” he wrote in a Facebook post.

Last year, the company drew headlines when a 17-year-old from Nebraska and her mother faced criminal charges for performing an illegal abortion after police obtained their Messenger chat history.

Anti-encryption advocates say that the technology makes it harder to find bad actors on messaging apps like WhatsApp, which is already encrypted by default.
