UPDATE (June 25th, 2021):

Twitter's under development reactions for tweets have been spotted once again. Dylan Roussel, an Android developer, was able to see them on his timeline but they were not working at the time. In other words, he was able to browse through different reactions but was unable to use them. There are five different reactions that represent Like, Cheer, Haha, Sad, and Hmm. It seems like we are closer than ever to get the public release of Twitter reactions.

Twitter is reportedly looking to offer more reaction options to users to help them express themselves better. It has offered "Heart" as the only way to react to tweets which is usually associated with liking the opinion. The team is now looking to change that by adding more diverse reaction options similar to Facebook Reactions.

Jane Manchun Wong (@wongmjane), a well-known app researcher, has tweeted that there are currently five Twitter Reactions under development. These include Like, Cheer, Hmm, Sad, and Haha. There are dedicated icons for these reactions except for Cheer and Sad. These two can be seen with the generic "heart" icon next to them.

The team is said to be testing these new reactions for the last two weeks. It is difficult to say exactly when and if these reactions will be made available to the general public. It goes without saying that Twitter's main priority is to get these reactions right instead of rolling them out as soon as possible. It would want to ensure that the reactions do not end up getting used for spreading negativity or targeting a particular user in a negative way.

Reactions are not the only thing that Twitter is working on recently. It has a paid subscription service called Twitter Blue under works as well. The team has rolled out Ticketed Spaces as a way for room hosts to generate revenue. It also resumed the account verification process just a couple of weeks ago but it has been paused once again since then.
