As part of the infrastructure, git keeps the commit sha of where you are using the submodule (i.e. why you need to commit in the parent when you update the child - you changed what commit of the submodule is being used!). This is because every "client" of that repository could be using it at a different version. This becomes important where you don't want to change or update one client as you add new features (and bugs), but want others to use the latest.crashmstr– crashmstr2017-04-05 19:12:58 +00:00Commented Apr 5, 2017 at 19:12

How to Tag
A tag is a keyword or label that categorizes your question with other, similar questions. Choose one or more (up to 5) tags that will help answerers to find and interpret your question.
- complete the sentence: my question is about...
- use tags that describe things or concepts that are essential, not incidental to your question
- favor using existing popular tags
- read the descriptions that appear below the tag
If your question is primarily about a topic for which you can't find a tag:
- combine multiple words into single-words with hyphens (e.g. python-3.x), up to a maximum of 35 characters
- creating new tags is a privilege; if you can't yet create a tag you need, then post this question without it, then ask the community to create it for you
