\section{Introduction}
\label{sec:intro}

Since last few decades, the Brazilian Federal Government has been improving its software adoption and development processes. In 2003, the recommendation to adopt free software become a public policy. In this context, in 2007, the Brazilian Ministry of Planning, Budget, and Management had released a Portal to share projects like free software called Brazilian Public Software (\textit{Software Público Brasileiro} -- SPB) \footnote{\url{https://softwarepublico.gov.br}}. In short, a website to share softwares developed by and for the Brazilian Government.

On the one hand, the Brazilian legal instrument (IN MP/SLTI 04/2014) \cite{IN04:2014} on software contracting indicates that the public managers must consult the SPB Portal to adopt a software solution, as well as, justifying the acquisition of proprietary softwares if there is no a similar project available in the SPB Portal. On the other hand, since 2009, the SPB Portal had several technical problems because there was no development activities to maintenance and evolute it. Thus, the initial SPB Portal version did not have another release.

During 2014 and 2016, a platform for the Brazilian Public Software project was designed and developed by the University of Brasília and the University of São Paulo. This new Portal was designed to be an integrated platform of collaborative software development environments with social networking, mailing list, control version system, and source code quality monitoring. In this paper, we present this new generation of the SPB Portal.
