Subversion project announcements
In December 2010, WANdisco announced their intention to undertake major work on the Subversion project, specifically aimed at improving branching and merging functionality. These changes had been proposed by the community previously but there had been no activity towards implementing them. WANdisco stated that demand from their enterprise customers had led to the decision to commit resources in this area.Some perceived the timing and manner of the announcement to be controversial and at odds with the Apache Software Foundation's position as leaders of the Subversion project. David Richards from WANdisco clarified this position stating that he in no way wished to undermine the Subversion community and followed up by announcing WANdisco's sponsorship and ongoing support for the work of the Apache Software Foundation.
