## 🔧 Breaking Changes from v0.3.0
|
||||
|
||||
### Cargo Feature Flags
|
||||
```toml
|
||||
# OLD (v0.3.0):
|
||||
[features]
|
||||
default = ["python-bindings"] # Always included
|
||||
|
||||
# NEW (v1.0.0):
|
||||
[features]
|
||||
default = [] # No default features
|
||||
python-bindings = ["pyo3", "numpy"] # Opt-in
|
||||
```
|
||||
|
||||
**Impact:**
|
||||
- Rust-only users: No breaking changes (python-bindings not needed)
|
||||
- Python users: No impact (maturin automatically enables python-bindings)
|
||||
|
||||
If you're using OptimizR as a Rust library and explicitly depend on Python bindings:
|
||||
```toml
|
||||
# Update your Cargo.toml:
|
||||
[dependencies]
|
||||
optimizr = { version = "1.0", features = ["python-bindings"] }
|
||||
```
|
||||
|
||||
## 📝 Migration Guide
|
||||
|
||||
### From v0.3.0 to v1.0.0
|
||||
|
||||
**For Rust Users:**
|
||||
No code changes required. If you were using python-bindings explicitly, add it to features list.
|
||||
|
||||
**For Python Users:**
|
||||
```bash
|
||||
# Upgrade via pip
|
||||
pip install --upgrade optimizr
|
||||
|
||||
# Or specify version
|
||||
pip install optimizr==1.0.0
|
||||
```
|
||||
|
||||
**API Compatibility:**
|
||||
✅ All Python APIs remain unchanged
|
||||
✅ All Rust APIs remain unchanged
|
||||
✅ Function signatures are identical
|
||||
✅ Return types are identical
|
||||
✅ No deprecations or removals
|
||||
|
||||
