In 1984 and thenceforth, the pentathlon (five events over two days) was replaced by the heptathlon (seven events over two days), so "discontinued" is not precisely correct. The heptathlon consists of the 200 meter and 800 meter runs, the 100 meter hurdles, the shot put, the javelin throw, the high jump, and the long jump in track and field: three track events and four field events.
The IOC did not initially decide to regrade the results, as silver medalist Ekaterini Thanou had herself been subsequently involved in a doping scandal in the run-up to the 2004 Summer Olympics. After two years of deliberation, in late 2009 the IOC decided to upgrade Lawrence and Ottey to silver and bronze respectively, and leave Thanou as a silver medallist, with the gold medal withheld.

Caster Semenya of South Africa was advanced to gold, Ekaterina Poistogova of Russia to silver, and Pamela Jelimo of Kenya to bronze. Poistogova herself was later found guilty of doping, but her Olympic results were unaffected, and the IOC decided to upgrade her medal.
^On 17 August 2015, the Court of Arbitration for Sport says it approved a settlement agreed to by Turkish athlete Aslı Çakır Alptekin and the IAAF. Alptekin has agreed to forfeit her 1500 metres Olympic title and serve an eight-year ban for blood doping.12 On 29 March 2017, Turkish athlete Gamze Bulut was banned for doping and lost her Olympic silver medal. Maryam Yusuf Jamal of Bahrain was advanced to gold, the silver medal was awarded to Tatyana Tomashova of Russia, and the bronze medal was awarded to Abeba Aregawi of Ethiopia. Tomashova was earlier found guilty of doping and missed the 2008 Olympics because of that, and was banned after the Olympics for failing another drug test.3
