On 10 May 2021, new projects created on CITnet will provide 'read access' by default to authenticated CITnet users. (There are no changes to commit or 'write access'.)The new default shows the support of commission management for open source."Read access will help Commission software developers discover, reuse and contribute to software tools and components created by other teams, across Directorates-General and Agencies. An increase in cooperation, standardisations and interoperability are obvious benefits," Thomas Gageik, director for Digital Business Solutions (DIGIT B), wrote to the information resource managers at the Commission and Executive Agencies, in an ARES note sent on 15 April. The day before, Mr Gageik had already announced the new default at the digital stakeholder forum (DSF).
