After introducing all new emoji with skin tone modifiers in iOS 8.3 beta 2, Apple continues to make minor tweaks to the emoji library in subsequent beta releases. iOS 8.3 beta 4 released through Apple's public beta testing program on Tuesday now separates default emoji from modified ones when holding them down on the keyboard, and emojis with yellow skin tone now have a matching blond or gold hair color.
The emoji keyboard also shows the "Recently Added" view as default again, making it easier to select from the emojis that you use most often for messaging. iOS 8.3 beta 4 also gains iMessage filtering that separates messages sent from unknown senders, removes the beta label from iCloud Photo Library and includes a number of bug fixes outlined within the MacRumors discussion forums.
