**Upgrade Urgency:** 🔴 CRITICAL (fixes application-breaking SyntaxError)

---

### 🔧 Critical Fixes

#### **Application Loading Issue Resolved** (CRITICAL)
- **FIXED**: SyntaxError in `specpulse/core/validation_rules.py:477`
- **ISSUE**: f-string expression containing backslash (`\n`) caused import failure
- **SOLUTION**: Extracted count operation outside f-string expression
- **IMPACT**: CRITICAL - prevented entire application from loading and all tests from running
- **TEST**: Added comprehensive test coverage in `tests/unit/test_bugfixes.py`

#### **Version Check System Fix** (CRITICAL)
- **FIXED**: Type mismatch in `specpulse/utils/version_check.py:69,109`
- **ISSUE**: Function signature declared return type `str` but actually returned tuple `(str, str)`
- **SOLUTION**: Updated return type annotation to `Tuple[str, str]`
- **UPDATES**: Modified all callers to properly unpack the tuple:
  - `specpulse/cli/handlers/command_handler.py`
  - `specpulse/cli/commands/project_commands.py`
- **IMPACT**: CRITICAL - caused incorrect behavior in version checking and validation

#### **Memory Display Fix** (HIGH)
- **FIXED**: Variable typo in `specpulse/core/memory_manager.py:290`
- **ISSUE**: Missing dot operator in f-string: `{entryimpact}` → `{entry.impact}`
- **SOLUTION**: Added proper dot operator for variable access
- **IMPACT**: HIGH - rendered literal text "entryimpact" instead of actual impact values
- **RESULT**: Memory entries now display impact levels correctly

### 🧪 Testing & Verification

# AFTER (fixed):
newline = "\n"
count = len([item for item in items if f"prefix{newline}{item}" in text])

# Bug #2: Type mismatch
# BEFORE (broken):
def check_version() -> str:
    return version, timestamp

# AFTER (fixed):
def check_version() -> Tuple[str, str]:
    return version, timestamp
# All callers updated: version, timestamp = check_version()

# Bug #3: Variable typo
# BEFORE (broken):
f"Impact: {entryimpact}"

## [2.2.4] - 2025-10-14

### ✅ Critical Fix - Template Files Verified Working

**RECOMMENDED**: This is the recommended stable version - all template files working

#### Fixed

- **VERIFIED**: Template files now properly bundled and loading correctly
  - Added `__init__.py` to `specpulse/resources/templates/`
  - Added `__init__.py` to `specpulse/resources/templates/decomposition/`
  - Created `MANIFEST.in` for explicit file inclusion
  - Templates recognized as proper Python packages

- **TESTED**: Local installation verified
  - Templates load from actual files (no embedded fallbacks)
  - No warnings during `specpulse init`
  - Clean user experience confirmed

#### What This Fixes

**Issue**: v2.2.0-2.2.3 had template files in source but they weren't properly bundled in the wheel/sdist packages due to missing `__init__.py` files.

**Solution**: Added `__init__.py` files to make templates/ a proper Python package, plus `MANIFEST.in` for explicit inclusion.

**Result**: Users now get actual template files, not embedded fallbacks.

#### Verification

```bash
pip install --upgrade specpulse  # Gets v2.2.4
specpulse init my-project
# Result: NO template warnings! ✅
```

**This is the MOST STABLE and COMPLETE release** - recommended for all users.

## [2.2.1] - 2025-10-14

### 🔧 Hotfix Release - Import Error Fix (superseded by v2.2.2)

**UPGRADE**: Use `pip install --upgrade specpulse` to get this hotfix

#### Fixed

- **CRITICAL**: Fixed missing `List` import in `service_container.py`
  - v2.2.0 had `NameError: name 'List' is not defined` when loading module
  - Added `List` to typing imports
  - Package now loads correctly

#### Changed

- Updated `specpulse/_version.py`: `2.2.0` → `2.2.1`

#### Technical Details

The v2.2.0 release had an oversight where `List` was used in type hints but not imported from `typing`. This caused a `NameError` when attempting to import the package, making v2.2.0 unusable.

This hotfix adds the missing import and publishes a working version.

**Affected**: v2.2.0 only
**Fixed in**: v2.2.1
**Impact**: All v2.2.0 features now working correctly
