📝 Walkthrough

Walkthrough

This pull request updates version references across two configuration files. In config/assembler.yml, the shared_configuration.stack anchor's current value is bumped from 9.3 to 9.4, while next is updated from 9.4 to main. In config/versions.yml, the stack.current version is incremented from 9.3.4 to 9.4.0. These changes align the version numbering scheme between the two configuration sources.

Inline comments:
In `@config/assembler.yml`:
- Around line 59-60: Update the references.ecs.current value from "9.3" to "9.4"
so assembler references align with the 9.4 release bump (the diff shows current:
9.4 and next: main); locate the references.ecs.current entry in the assembler
configuration and change its value to "9.4" to keep the GA configuration
consistent with the stack version.

In `@config/versions.yml`:
- Line 6: Update the remaining version keys to match the GA bump: change
ecs.current and edot-collector.current values from 9.3.x to 9.4.0 so they are
consistent with stack.current (9.4.0); locate the ecs.current and
edot-collector.current entries in the same versions.yml and set both to "9.4.0"
and ensure formatting matches the surrounding YAML.
