TortoiseSVN is a really easy to use Revision control / version control / source control software for Windows. It is based on Subversion. TortoiseSVN provides a nice and easy user interface for Subversion.
It is developed under the GPL. Which means it is completely free, including the source code. But just in case you don't know the GPL too well: you can use TortoiseSVN to develop commercial applications or just use it in your company without any restrictions.
Since it's not an integration for a specific IDE like Visual Studio, Eclipse or others, you can use it with whatever development tools you like.
As a Subversion client, TortoiseSVN has all the features of Subversion itself, including:
- Most current CVS features.
- Directories, renames, and file meta-data are versioned.
- Commits are truly atomic.
- Branching and tagging are cheap (constant time) operations.
- Efficient handling of binary files.
- BUG: Performance issue if dragging lots of files in the explorer.
- BUG: "Show unified diff" in the log dialog did not include the last (lowest) revision.
- BUG: Adjusting externals to the HEAD revision used always the same revision if multiple externals were selected.
- BUG: "Check all" in project monitor cleared the view.
- BUG: When uninstalling TSVN, files from an installed language pack were left.
- BUG: IDiff showed 256x256 icons with wrong size.
- NEW: new library icon for Win10, new overlay icon set for Win10.
- CHG: TortoisePlink uses new UX style.
- BUG: "update all" was enabled even if there are no monitored working copies in the project monitor.
- CHG: The option "LogFindCopyFrom" is now enabled by default, and revisions before the merge branch are grayed.
- BUG: A blame started from the log dialog ignored the blame options from the dialog.
- BUG: The option "Reopen dialog after commit if items were left uncommitted" was shown as active in the settings dialog, even though it was not.
