+Notes on making a new release of libarchive
+===========================================
+
+The following serves as a guide for libarchive developers on the general
+process to be followed when making a new release of libarchive.
+
+* Update build/version with the version number of the release to be made.
+* If the library's ABI has changed, the library's soname major version *MUST*
+ be updated. Update configure.ac and CMakeLists.txt appropriately.
+ - For configure.ac, the variable ARCHIVE_INTERFACE needs to be updated.
+ - For CMakeLists.txt, the variable INTERFACE_VERSION needs to be updated.
+* Update the entries in the NEWS file accordingly.
+* Run `build/makerelease.sh` from the top source directory. Running this script
+ will do the following.
+ - Removes all Makefile.am development build specific CFLAGS from
+ Makefile.am.
+ - Update configure scripts and header files with the appropriate version
+ number from build/version.
+ - Rebuild the documentation directory.
+ - Runs a full cmake build and test.
+ - Runs a full autotools build and test.
+ - Builds the .tar.gz and .zip distribution files.
+* Commit all changed files into git.
+ - This should be build/version, NEWS, and the files edited by running
+ build/makerelease.sh.
+* Tag the release appropriately. The tag should also have an appropriate
+ message.
+ - The git command is as follows:
+ $ git tag -m "Libarchive <version>" v<version>
+ Replace <version> with the version to be released.
+* Copy all the generated wiki files and commit them into the libarchive.wiki
+ repository. Overwrite any preexisting files with the same name (these files
+ are always autogenerated from the libarchive release after every release).
+* Update the libarchive.github.com website accordingly.
+* Make an announcement to the libarchive-announce mailing list.
