I wasn't aware that command even existed. However, I suspect it will
cause issues in your use case. I'm not sure it is a good command to
actually have given the complexities associated with getting a clean org

In many cases, you may not run into issues - especially if you do a git
pull frequently. However, I can see various scenarios which will lead to
inconsistent builds. I suspect the error you are seeing is the result of
recent work to try and identify builds which are likely to result in an
inconsistent 'mixed' version build. Detecting such scenarios is
difficult and relies on a number of heuristics, one of which is to flag
a problem if the loaded version and the target build version don't

A lot would depend on how you build (re-compile) org mode after doing a
git pull. If you compile it in a separate Emacs instance, you should
have less issues and reloading after the build will likely
work. However, if your trying to build org mode within the running Emacs
where you have already loaded org mode, I suspect you will run into
issues. You have a slight 'chicken and egg' issue and will run into
similar issues as the common mixed build problems.

One thing which might work would be to ensure you run the reload command
with the option to load from uncompiled sources BEFORE you run the build
process and then re-run the load command after the build (loading
compiled versions this time).

I have no idea how things might break given the new native compilation
modes in Emacs. I suspect it will cause all sorts of issue with your

Personally, I always update org in a fresh instance of Emacs (before any
org functionality is loaded) and I would always restart Emacs after
updating a major packages like org mode. I'm not sure why we have the
reload command - I suspect it may be a hang over from earlier attempts
to work around the mixed build problem. I do suspect that given new
native compilation modes and the additional complexity ths can cause,
combined with increasing org mode complexity, the notion of being able
to pull down a new version, build and reload it within one emacs
instance is perhaps flawed or at the very least, is more complex than
just forcing a reload of org *.elc files. .
