In the middle of the fifth and final spacewalk right now. The repair of the STIS yesterday was successful, but because of a handle bolt issue earlier, the spacewalkers didn't have time to replace some of Hubble's thermal covering as planned, so that had to be tacked onto the end of today's spacewalk. It seems like they've already successfully replaced the final battery assembly and the broken Fine Guidance Sensor, so they're now working on some of that thermal covering.
All things considered, this mission seems like a resounding success so far. The only setback I can think of is the fact that the High Resolution Channel on the ACS didn't come back online, but that was considered a long shot at best, and the Wide Field Channel that was specifically targeted by the repair seems to be working just fine now. This mission will definitely wind up breaking just about every boundary or what sort of repairs can be pulled off in-situ.
