## Unreleased

    

  
    

      
      4
      +
      

    

  
    

      
      5
      +
      
Measured on the Linux kernel's tree (95 943 files); `docs/benchmarks.md` has the tables.

      +

      +
      
- **Faster than Git on the first commit, a clean status, fsck, gc and the pack's size.**

    

  
    

      
      8
      +
      
  - **First commit:** 21.9 s (Git 33.7 s).

    

  
    

      
      9
      +
      
  - **Clean status:** 0.17 to 0.19 s (Git 0.22 s).

    

  
    

      
      10
      +
      
  - **fsck:** 8.2 s (Git 12.6 s).

    

  
    

      
      11
      +
      
  - **gc:** 33.7 s (Git 70 s).

    

  
    

      
      12
      +
      
  - **The pack:** 293.5 MB (Git's 295.5 MB).

    

  
    

      
      13
      +
      
- **Level with Git on a local clone (about 17 s).** Status with one file changed, diff, commit, log, blame and checkout are two to six times faster than at 0.1.0. They are still behind Git:

    

  
    

      
      14
      +
      
  - **Status with one file changed:** 0.41 s, against 0.22 s.

    

  
    

      
      15
      +
      
  - **Commit:** 0.67 s, against 0.21 s.

    

  
    

      
      16
      +
      
  - **Blame:** 0.16 s, against 0.07 s.

    

  
    

      
      17
      +
      
  - **Checkout:** 0.74 s, against 0.35 s.

    

  
    

      
      18
      +
      
- **A project's `.gitignore` files count**, below `.oxyignore`. A project coming from Git no longer commits its build output, and `!` in `.oxyignore` can bring back what `.gitignore` leaves out. Ignore rules still apply to untracked paths only.

    

  
    

      
      19
      +
      
- **A folder holding a repository of its own is named.** `oxy status`, `oxy commit` and `status --json` (`untracked_nested`) name a folder with its own `.git` or `.oxy`, rather than skipping it silently. They say how to track its files, keep it as a subrepo, or leave it out.

    

  
    

      
      20
      +
      
- **`oxy rebase CHANGE --onto T --into-working-copy`.** Where a rebase would be conflicted, the target is merged into the current bookmark instead, and the conflict is resolved in the working copy, as after `oxy merge`.

    

  
    

      
      21
      +
      
- **mimalloc is the allocator.** Most of the speed above came from it: status, walks and index loads allocate many small values from every thread.

    

  
    

      
      22
      +
      
- **Internals.** Each item below is a cache and is rebuilt when it does not check:

    

  
    

      
      23
      +
      
  - the workspace manifest is a checksummed binary file;

    

  
    

      
      24
      +
      
  - the state index is decoded lazily, caught up by replaying a few changes, and kept for the last two states;

    

  
    

      
      25
      +
      
  - the store caches change metadata;

    

  
    

      
      26
      +
      
  - a pack can carry a trained zstd dictionary.

    

  
    

      
      27
      +
      

    

  
    

      
      28
      +
      
## 0.1.0 (2026-09-30)

    

  
    

      
      29
      +
      

    

  
    

      
      30
      +
      
- **The first builds for people to download.**

    

  
    

      
      31
      +
      
  - Linux x86_64 and arm64 (glibc 2.28 or later) as `.tar.gz` and `.deb`.

    

  
    

      
      32
      +
      
  - macOS x86_64 and arm64.

    

  
    

      
      33
      +
      
  - Windows x86_64.

    

  
    

      
      34
      +
      

    

  
    

      
      35
      +
      
  All are cross-compiled from Linux with `scripts/dist.sh`, with SHA256SUMS. A prerelease: formats may still change before 1.0.
