Tickers on Oslo Børs have not been updated.

[loldot]

This weekend Oslo Børs was moved to Euronexts trading platform. As a consequence, some tickers were changed, these changes are not implemented in the market stack API. For instance using the correct ticker BOUV.XOSL for the company Bouvet ASA I do not get a result, and using the old ticker I only receive data from before the change. See examples of batch requests below, where I request one security where the ticker remains unchanged (SVEG.XOSL), and either BOUV.XOSL or BOUVET.XOSL. The list of changed tickers can be found here: https://newsweb.oslobors.no/message/519215
