The Swedish Corporate Governance Board took over the responsibility for the takeover rules of the stock exchange in connection with the closure of Näringslivets Börskommitté, (NBK), the Business and Industry Committee, in 2010. See http://www.naringslivetsborskommitte.se

The Board has revised the rules on three occasions: in 2015, 2017 and 2018 (the version currently applicable).

Here you can find previous versions of the Takeover Rules in clean versions and annotated versions showing changes compared with the previous version.
