Bluesky updates username policy to enhance user security and convenience

Bluesky has introduced an update that protects users' old usernames when they switch to a personal domain name. Previously, users risked losing their old handle to others if they did not claim it immediately after the change. With the new feature, Bluesky will reserve the most recent bsky.social handle indefinitely, preventing impersonation and username squatting. This change aims to enhance user security and convenience. The update also includes a new "Mentions" tab for easier notifications, options for viewing replies in different formats, and visual improvements. Additionally, Bluesky now supports three new languages: Khmer, Nepali, and Romanian.
