It was only a couple of days ago that AltStore received an update in the form of a public beta to resolve a an issue where apps installed after January 28th would crash after the user tried launching them. This was a temporary (yet agonizing) issue for jailbreakers, and for that reason, it may come as no surprise that an official AltStore update would be imminent.
Tuesday afternoon, that very update materialized as AltStore and AltServer version 1.4.3 officially became available to the general public Worthy of note, this update is different from the public beta that launched two days ago, as it's an official public release as opposed to just a public beta build.
