## [Unreleased]

## [2.0.0] - 2026-01-15

### BREAKING CHANGES

**Group ID Migration: `io.brewkits` → `dev.brewkits`**

This version introduces a breaking change to align with domain ownership for Maven Central.

**What Changed:**
- Maven artifact: `io.brewkits:kmpworkmanager` → `dev.brewkits:kmpworkmanager`
- Package namespace: `io.brewkits.kmpworkmanager.*` → `dev.brewkits.kmpworkmanager.*`
- All source files (117 files) updated with new package structure

**Migration Required:**
```kotlin
// Old (v1.x)
implementation("io.brewkits:kmpworkmanager:1.1.0")
import io.brewkits.kmpworkmanager.*

// New (v2.0+)
implementation("dev.brewkits:kmpworkmanager:2.0.0")
import dev.brewkits.kmpworkmanager.*
```

**Why?**
- Aligns with owned domain `brewkits.dev`
- Proper Maven Central ownership verification
- Long-term namespace stability

See [DEPRECATED_README.md](DEPRECATED_README.md) for detailed migration guide.
