The Versioning tab of the Miscellaneous category contains settings for version control systems supported by the IDE. Built-in support is provided for CVS, Mercurial, and Subversion, as well as the Local History feature. Other version control systems may be supported by plug-ins.
The Versioning tab in the Fonts & Colors category contains additional version control related settings.
Local History is similar to a classic versioning system in that it stores multiple versions of files. However, the storage is only local to your NetBeans installation. Local history enables you to examine content of files and folders back in time, lets you diff them and most importantly lets you rollback your sources to some previous state or revert already deleted files or folders. Here you can set the number of days that the local history will be maintained.
