🛤️ tracking: 5.4 Release Checklist

[runspired]

• Previous Release Tracker (5.3)

Implementation notes for the Roadmap

Overview

The primary focus of this release will be on the early stages of SchemaRecord. Its likely that most work will take place as POCs and RFCs. We will not ship new SchemaRecord or SchemaDSL features unless we're ready to do so.

🌲 Deprecation RFCs

We want to land RFCs and implementations for the following.

• Deprecate Store service extending EmberObject #8874 RFC#1026 IMPL
• SchemaService Updates

🦓 Miscellaneous

• Improve Config Handling for polyfillUUID for 4.12+ #8675
• Add tests for lifetimes service using new http mock
• Expand tests for Fetch handler using new http mock

🪴 Feature RFCs

We want to land RFCs for the following, shipping the actual implementation is less likely.

• Improved SchemaService #8881 RFC#1027
• [-] Paginated Relationships #8882
• Basic SchemaRecord #8883

[runspired]

SchemaRecord has reached feature parity with @ember-data/model, which is a potential bar for shipping 5.4

Ideally we polish the ModelFragments parity story first.

After Review, some additional things to land for SchemaRecord to be stabilized:

Testing

• write even more tests for immutability (e.g. user MUST call record.checkout)
  • what happens when you try to mutate a related record from a checked out record, does it auto-checkout or does it error? preference towards explicit checkout
• write tests around what happens when you set object/array/schema-object/schema-array onto a different record than they are on initially (should copy and both records now have a version)

Feature Work

• alias field
• non-editable / read-only version of the record should not show mutated state CacheV3
  • peek remote state only
  • peek mutated state
  • rollback of mutated state for a single property
  • peek change of state for a single property
