Is anyone else get irritated while upgrading apps and seeing changelogs as:
1. minor improvements
2. performance boost
3. information not provided by the dev
4. repeating changelogs from the past few updates.

just tell me what minor improvement u fixed?
where performance is boost?
how can I trust if tomorrow you decide to add some malicious code.

I don't know but it really irritates me. Sometimes I don't even upgrade the app until they have something in the changelog.

Maybe because I am getting old now.

Often there could be hundreds of small things like better error handling and similar.

Listing all would be quite uninteresting, and frankly, how many here live writing documentation or change logs ;)

Public change logs usually inly contain relevant info.

And security improvements, unless related to a well known problem are rarely put in public change logs, especially if there is a risk there will be un updated versions in circulation.

As for what I want to be shown:
Is it relevant to point out every minor fix in a app store changelog? I would say no, a generic "bug fixes" can be okay for those. 99.9% wouldn't understand or care anyway and it would just add noise. I would like to have changes listed though (especially and feature changes and changed UX) and having an optional full changelog would be great.

However the issue is also that app store changelogs are broken by design:

Firstly it isn't obvious to you which version you have installed and which version you update to.

Secondly changelogs are not aggregated but replaced. If you update from e.g. 1.0 to 1.3 you'll see the changelog for 1.3 (or from 1.2.x to 1.3) and not the changes from 1.0 to 1.1 and 1.1 to 1.2. Didn't install the 2.0 update for a while? Great, we'll show you the changelog for 2.1, expecting that you already know about the 2.0 changes.

@F1973 totally agree. Big companies should totally mention changelog.
Infact app store platforms should have a proper rule regarding changelogs.
