You may backport new translations for modules that have already been released.
A FOLIO release like Honeysuckle, Iris, etc. ships with the translations that come with each front-end module. Each front-end module has a different release date (Honeysuckle example). This is the time when translations are taken from module's GitHub translations directory and is different for each front-end module. A new front-end module release is needed to get more recent translation included into a FOLIO release.
However, the sysOp of a FOLIO installation may manually update the translations of their installation by exchanging the files in the
/translations/ directory from where the static files are shipped.
One option is to take the latest translations from https://folio-testing.dev.folio.org/ .
Do to it manually use the browser developer tools to find out the current number folio-testing uses, for example
https://folio-testing.dev.folio.org/translations/de-1605513539114.json. If you own installation has
de-1601343197440.json merge them:
jq -s '. * .' de-1601343197440.json de-1605513539114.json > de-1601343197440.json.new
Then use the joined file:
mv de-1601343197440.json.new de-1601343197440.json
To do it automatically use this script:
