[rebkwok]

This issue is to track subtasks and progress on the coding system releases. See also comments on the initial investigation issue.

• New release model and extraction of current coding system data to separate databases Coding system versions: part 1 #1397
• Make coding system methods use the relevant separate databases Coding System Versions: Part2 #1401
• Implement coding system versions in the mappings apps #1411
• Implement coding system versioning for importing new data #1409
• Record coding system releases compatibility for codelist versions #1441
• Select a coding system release when creating a new codelist/draft #1421
• Include coding system release in API endpoint for OSI #1445
• Mappings between coding systems #1433 (futher mapping questions)
• Separate CTV3 and TPP-CTV3 coding systems #1448
• Short-term solution for superceded dm+d codes #1449
• Options in interface to diff codelist versions - this exists already but isn't obvious or documented (see Description of 'diff' functionality in opencodelists docs #1148); when there are options to create versions of codelists from different relaeses, it's likely to be useful and should be more easily accessible
• Automate dm+d coding system updates #1469
