- 50. Features that Pijul Features that Pijul promises promises distributed version control simple, because of its basis on a sound theory of patches fast, because it aims to fix the Darcs performance issues interactive recording https://www.pijul.com https://www.pijul.com

- 53. Patch-oriented design Patch-oriented design A patch is an intuitive atomic unit of work. It focuses on changes, instead of differences between snapshots (i.e. Git commits). Applying or unapplying a patch doesn't change its identity. The end result of applying several patches is always the same, regardless of the order in which they were applied. Pijul keeps track of 'dependent patches' No merges or rebases; applying a patch is like git cherry-pick.

- 57. Pijul towards v1.0 Pijul towards v1.0 New change format; 'patches' are now called 'changes' 'Branches' are now called 'channels' Better support for large files and repositories by compressing changes Interactive recording is replaced by a 'change draft screen' Version identifiers that don't depend on any order Inclusive author names Documentation is lagging a bit

- 66. Now what? Now what? A lot of projects are nothing like the Linux kernel. So try Fossil for a change! Git's snapshotting might be too technical for the average Git user. So try Pijul for a change!
