More famous Soviet Mir station was launched the next year (1986.) but the Salyut-7 remained operational few more years.
As a matter of fact, the crew of Mir on one occasion conducted transfer aboard Salyut-7 via Soyuz-pod in order to collect some advanced equipment and install it back on the Mir - a feet off transfer in space that most likelly won't be repeated so soon by any nation.
May be of interest how that repair from 1985. was the time when the first female cosmonaut stayed in open space (Svetlana Savitskaya); one year after the NASA did the same (Kathryn Sullivan).
I quite enjoyed the biographical movie on the dramatic rescue, that was released in 2017.
