 Go bindings for [libgit2](http://libgit2.github.com/).
 
+### Updated 2024/12/16

 ### Which Go version to use
 
-Due to the fact that Go 1.11 module versions have semantic meaning and don't necessarily align with libgit2's release schedule, please consult the following table for a mapping between libgit2 and git2go module versions:
-
-| libgit2 | git2go        |
-|---------|---------------|
-| main    | (will be v34) |
-| 1.3     | v33           |
-| 1.2     | v32           |
-| 1.1     | v31           |
-| 1.0     | v30           |
-| 0.99    | v29           |
-| 0.28    | v28           |
-| 0.27    | v27           |
-
-You can import them in your project with the version's major number as a suffix. For example, if you have libgit2 v1.2 installed, you'd import git2go v33 with:
+* This package is updated to work against libgit2 version 1.8 on Debian sid
+* There is one line commented out which needs to be fixed in remote.go
+* some of the tests seem to run
 
 ```sh
-go get github.com/libgit2/git2go/v33
-```
-```go
-import "github.com/libgit2/git2go/v33"
+go install go.wit.com/apps/go-clone@latest
+go install go.wit.com/apps/go-mod-clean@latest
+go-clone --recusive go.wit.com/lib/libgit2
 ```
 
-which will ensure there are no sudden changes to the API.
-
-The `main` branch follows the tip of libgit2 itself (with some lag) and as such has no guarantees on the stability of libgit2's API. Thus this only supports statically linking against libgit2.
 
 ### Which branch to send Pull requests to
 
-If there's something version-specific that you'd want to contribute to, you can send them to the `release-${MAJOR}.${MINOR}` branches, which follow libgit2's releases.

 When linking dynamically against a released version of libgit2, install it via your system's package manager. CGo will take care of finding its pkg-config file and set up the linking. Import via Go modules, e.g. to work against libgit2 v1.2
 
 ```go
-import "github.com/libgit2/git2go/v33"
+    goimports -w *.go
 ```
 
-### Versioned branch, static linking
-
-Follow the instructions for [Versioned branch, dynamic linking](#versioned-branch-dynamic-linking), but pass the `-tags static,system_libgit2` flag to all `go` commands that build any binaries. For instance:
-
-    go build -tags static,system_libgit2 github.com/my/project/...
-    go test -tags static,system_libgit2 github.com/my/project/...
-    go install -tags static,system_libgit2 github.com/my/project/...
-
-### `main` branch, or vendored static linking
-
-If using `main` or building a branch with the vendored libgit2 statically, we need to build libgit2 first. In order to build it, you need `cmake`, `pkg-config` and a C compiler. You will also need the development packages for OpenSSL (outside of Windows or macOS) and LibSSH2 installed if you want libgit2 to support HTTPS and SSH respectively. Note that even if libgit2 is included in the resulting binary, its dependencies will not be.
-
-Run `go get -d github.com/libgit2/git2go` to download the code and go to your `$GOPATH/src/github.com/libgit2/git2go` directory. From there, we need to build the C code and put it into the resulting go binary.
-
-    git submodule update --init # get libgit2
-    make install-static
-
-will compile libgit2, link it into git2go and install it. The `main` branch is set up to follow the specific libgit2 version that is vendored, so trying dynamic linking may or may not work depending on the exact versions involved.
-
-In order to let Go pass the correct flags to `pkg-config`, `-tags static` needs to be passed to all `go` commands that build any binaries. For instance:
-
-    go build -tags static github.com/my/project/...
-    go test -tags static github.com/my/project/...
-    go install -tags static github.com/my/project/...
-
-One thing to take into account is that since Go expects the `pkg-config` file to be within the same directory where `make install-static` was called, so the `go.mod` file may need to have a [`replace` directive](https://github.com/golang/go/wiki/Modules#when-should-i-use-the-replace-directive) so that the correct setup is achieved. So if `git2go` is checked out at `$GOPATH/src/github.com/libgit2/git2go` and your project at `$GOPATH/src/github.com/my/project`, the `go.mod` file of `github.com/my/project` might need to have a line like
-
-    replace github.com/libgit2/git2go/v33 => ../../libgit2/git2go
-
 Parallelism and network operations
 ----------------------------------
 
-libgit2 may use OpenSSL and LibSSH2 for performing encrypted network connections. For now, git2go asks libgit2 to set locking for OpenSSL. This makes HTTPS connections thread-safe, but it is fragile and will likely stop doing it soon. This may also make SSH connections thread-safe if your copy of libssh2 is linked against OpenSSL. Check libgit2's `THREADSAFE.md` for more information.
