 * Iterates through the list of commits looking for the keywords specified in config file for additional bumps of versions
 * Returns the semantic version which can be included in the release
 
+### Additional features
+
+* With flag `-e` or config `force.existing: true` the existing tags in versioning will be respected, helping you to avoid the version conflicts.
+* With config `force.commit: deadbeef` where `deadbeef` is the commit hash - calculations will start from the specified commit.
+
+### Important changes
+
+* From version `1.4.2+` as pointed out in [issue #12](https://github.com/lukaszraczylo/semver-generator/issues/12) commits from merge will not be included in the calculations and commits themselves will bump the version on first match ( starting checks from `patch` upwards ).
