We aim to cut a regular release every 3-4 months, approximately twice as frequent as major Bitcoin Core releases. Every second release should be published one month before the feature freeze of the next major Bitcoin Core release, allowing sufficient time to update the library in Core.

## Sanity Checks

|
||||
## Sanity checks
|
||||
Perform these checks when reviewing the release PR (see below):
|
||||
|
||||
1. Ensure `make distcheck` doesn't fail.
|
||||
```shell
|
||||
./autogen.sh && ./configure --enable-dev-mode && make distcheck
|
||||
```
|
||||
```shell
|
||||
./autogen.sh && ./configure --enable-dev-mode && make distcheck
|
||||
```
|
||||
2. Check installation with autotools:
|
||||
```shell
|
||||
dir=$(mktemp -d)
|
||||
./autogen.sh && ./configure --prefix=$dir && make clean && make install && ls -RlAh $dir
|
||||
gcc -o ecdsa examples/ecdsa.c $(PKG_CONFIG_PATH=$dir/lib/pkgconfig pkg-config --cflags --libs libsecp256k1) -Wl,-rpath,"$dir/lib" && ./ecdsa
|
||||
```
|
||||
```shell
|
||||
dir=$(mktemp -d)
|
||||
./autogen.sh && ./configure --prefix=$dir && make clean && make install && ls -RlAh $dir
|
||||
gcc -o ecdsa examples/ecdsa.c $(PKG_CONFIG_PATH=$dir/lib/pkgconfig pkg-config --cflags --libs libsecp256k1) -Wl,-rpath,"$dir/lib" && ./ecdsa
|
||||
```
|
||||
3. Check installation with CMake:
|
||||
```shell
|
||||
dir=$(mktemp -d)
|
||||
build=$(mktemp -d)
|
||||
cmake -B $build -DCMAKE_INSTALL_PREFIX=$dir && cmake --build $build --target install && ls -RlAh $dir
|
||||
gcc -o ecdsa examples/ecdsa.c -I $dir/include -L $dir/lib*/ -l secp256k1 -Wl,-rpath,"$dir/lib",-rpath,"$dir/lib64" && ./ecdsa
|
||||
```
|
||||
4. Use the [`check-abi.sh`](/tools/check-abi.sh) tool to ensure there are no unexpected ABI incompatibilities and that the version number and release notes accurately reflect all potential ABI changes. To run this tool, the `abi-dumper` and `abi-compliance-checker` packages are required.
|
||||
|
||||
```shell
|
||||
tools/check-abi.sh
|
||||
```
|
||||
```shell
|
||||
dir=$(mktemp -d)
|
||||
build=$(mktemp -d)
|
||||
cmake -B $build -DCMAKE_INSTALL_PREFIX=$dir && cmake --build $build --target install && ls -RlAh $dir
|
||||
gcc -o ecdsa examples/ecdsa.c -I $dir/include -L $dir/lib*/ -l secp256k1 -Wl,-rpath,"$dir/lib",-rpath,"$dir/lib64" && ./ecdsa
