According to an ECHA press release:
The European Chemicals Agency (ECHA) is going to release a new version of IUCLID 5 in late May 2012 and subsequently a new release of REACH-IT. Later this year, ECHA will start publishing more information on chemical substances.
Helsinki, 11 April 2012 - The new IUCLID 5.4 release will bring about changes mainly on how certain substance information included in the Chemical Safety Report (CSR) is reported. In addition, certain information included in the Safety Data Sheet (SDS) will be made publicly available. As a continuation of the IUCLID 5 update, a new version of REACH-IT will be released later in the summer. The new REACH-IT release will accept only IUCLID 5.4 dossiers. ECHA publishes a Question and Answer (Q&A) document to inform stakeholders in advance about the impact on the upcoming submissions of registration and other dossiers.
