Mercurial 1.9 Lançado!

Mercurial 1.9 Lançado!

Mercurial é mais um “sistema de controle de versão de distribuição open-source, como o Git. Mercurial foi concebido para projetos de maior envergadura, mais provavelmente fora do alcance da web designers e desenvolvedores independentes. Isso não significa que as pequenas equipes desenvolvimento não podem ou não devem usá-lo. Mercurial é extremamente rápido, e com o desempenho como a característica mais importante. O nome “mercurial” é um adjetivo que significa “Relativo a ou que tenham características (eloquência, rapidez, inteligência) atribuído ao deus Mercúrio.”

Para além de ser muito rápido e escalável, Mercurial é um sistema muito mais simples do que Git. Não há por enquanto muitas funções para aprender, e as funções são semelhantes às de outros sistemas CVS. Ele também vem equipado com uma interface Web stand-alone e extensa documentação sobre compreensão Mercurial se você estiver utilizando um outro sistema.
