In replacement of Halon 1301 are so called "clean agents" such as
hydofluorocarbons (HFCs), and Inert gases. The most popular version of each
is FM-200 and Inergen, respectively (trade names, their actual names being
heptafluoropropane HFC-227ea, and IG-541).

Halon is still superior to them in terms of fire suppression capability, and
are not required to be removed from existing installations so they'll still
be relevant for awhile as NFPA standard 12A continues to be revised every 3
years. One place to see widespread use of Halon are NYC subway station token
booths was for this reason:

I believe high pressure water mist is an acceptable alternative for computer
room protection, but still rather new.
