+
+### Pulling all repositories
+
+Empty command will now show help output
+
+```console
+$ vcspull sync
+Usage: vcspull sync [OPTIONS] [REPO_TERMS]...
+
+Options:
+-c, --config PATH Specify config
+-x, --exit-on-error Exit immediately when encountering an error syncing
+multiple repos
+-h, --help Show this message and exit.
+```
+
+To achieve the equivalent behavior of syncing all repos, pass `'*'`:
+
+```console
+$ vcspull sync '*'
+```
+
+Depending on how shell escaping works in your shell setup with [wild card / asterisk], you may not need to quote `*`.
+
+[wild card / asterisk]: https://tldp.org/LDP/abs/html/special-chars.html#:~:text=wild%20card%20%5Basterisk%5D.
+
+### Terms with no match in config will show a notice
+
+> No repo found in config(s) for "non_existent_repo"
+
+- Syncing will now skip to the next repos if an error is encountered
+
+- Learned `--exit-on-error` / `-x`
+
+Usage:
+
+```console
+$ vcspull sync --exit-on-error grako django
+```
+
+Print traceback for errored repos:
+
+```console
+$ vcspull --log-level DEBUG sync --exit-on-error grako django
+```
+
+### Untracked files
+
+Syncing in git repositories with untracked files has been improved (via libvcs
+0.17, https://github.com/vcs-python/libvcs/pull/425)
