Release v2.6.2 - S26B Call for Proposals

This release is prepared for the Subaru S26B Call for Proposals period and includes cumulative updates since v2.2.0 (S26A CfP release), focusing on modernization of the build system, developer experience improvements, and dependency updates.

🚀 What's New Since v2.2.0

Build System Modernization (v2.3.0)

• PR #35: Implemented setuptools-scm for dynamic versioning - version is now automatically derived from git tags
• PR #36: Added uv compatibility and modernized pyproject.toml to standard Python packaging format
• PR #37: Implemented nested year/month directory structure (YYYY/MM/) for ETC output files
• PR #38: Upgraded to NumPy 2.0+ compatible dependencies and removed unused FastAPI/Jinja2 files

Code Reorganization (v2.4.0)

• PR #39: Reorganized spectemplates directory structure for better maintainability

Simulation ID Cleanup (v2.5.0)

• PR #40: Removed YYYY/MM/ prefix from Simulation ID in tjtext files for cleaner identification

User Interface Improvements (v2.6.0)

• PR #45: Added version information display to sidebar for easier version verification
• PR #44 (OBSPROC-134): Removed deprecation warnings for cleaner output
• PR #41-43: Added GitHub Actions workflow to automatically update copyright year

Dependency Updates (v2.6.1 - v2.6.2)

• PR #46: Security update - urllib3 2.6.2 → 2.6.3
• PR #47: numpy 2.4.0 → 2.4.1
• PR #48: pfsspecsim updated to 1.5.1

📋 Technical Details

Key Infrastructure Changes

• Dynamic versioning via setuptools-scm (no more manual version bumps)
• Support for both uv and pdm package managers with auto-detection scripts
• Output files now organized in YYYY/MM/ directory structure
• Development dependencies (matplotlib, seaborn) moved to dev group

For Developers

• Use shell scripts in scripts/ directory for development workflow
• CLI entry point run_pfs_etc_web available but scripts are recommended
• Copyright year automatically updated via GitHub Actions

Release v2.2.0 - S26A Call for Proposals

This release is prepared for the Subaru S26A Call for Proposals period and includes important improvements to the PFS Exposure Time Calculator web application.

🚀 What's New

Default Parameter Updates

• OBSPROC-125: Updated default exposure setting to 2×450s for improved observation efficiency
• OBSPROC-126: Set default Moon Zenith Angle to 60 degrees for more realistic observing conditions
• Updated documentation to reflect the new default values

Enhanced Saturation Detection

• OBSPROC-123: Fixed total-to-per-pixel conversion for saturation calculations
• OBSPROC-112: Enhanced saturation detection and reporting in simulation
• Revised saturation thresholds and improved documentation
• Fixed saturation count scaling from total to per-pixel values

Bug Fixes and Improvements

• Fixed typos in spectral templates and regular expressions
• Used raw strings to properly escape regular and mathematical expressions
• Fixed reset functionality for observation parameter loops

• Added important notes about unrealistic observing conditions

📋 Technical Details

Key Changes Since v2.1.0

• Improved exposure time calculation accuracy
• Better handling of saturation limits
• More realistic default observing parameters
• Enhanced user interface responsiveness
• Better documentation and error messaging

For Proposal Preparers

This release provides:

• More accurate exposure time estimates
• Realistic default parameters based on typical PFS observing conditions
• Improved saturation warnings and detection
