@opticoder thanks for the PR! It actually defaults to true, so in the docs its actually correct

[opticoder]

@FabianKramm Thanks for the quick reply! But doesn't it mean then here https://www.devspace.sh/docs/configuration/deployments/#deployments-updateImageTags default value is not correct? And if yes, should I change the PR or create a new one?

[FabianKramm]

@opticoder oh yes! You are correct its actually wrong in the other place! Yes you can change this PR or create another one, both is fine! Thank you!

updated the fix for default to true

Closing in favor of #2714, since there were fixes to the documentation generation code needed to avoid overwriting this change.
