Release v0.2.0: Sequential mode improvements and refactoring - #289
Merged
Conversation
Bump version from 0.1.3 to 0.2.0 in pyproject.toml and uv.lock, and finalize the CHANGELOG for the 0.2.0 release: integer strategy and thermal heuristics, lower_bound()/upper_bound() expression operators, the configurable sequential-mode carry-over-length, the linopy >= 0.9.0 upgrade (Python >= 3.11), the optim-config parsing/validation split, and the fast-heuristic and hybrid port-type fixes that landed since 0.1.3.

The deleted models-design/ folder was repo-internal tooling never shipped in the package, so it does not belong in the user-facing changelog. Co-Authored-By: Claude Opus 5 <noreply@anthropic.com> Claude-Session: https://claude.ai/code/session_01QwP1EdXwXBpTQdTqT7U5yP

Description
This PR releases version 0.2.0 with several significant improvements and refactoring:
Key Changes
Sequential mode carry-over length is now user-controlled - Introduces a new
resolution.carry-over-lengthparameter (default:block-overlap) that allows users to control how many shared leading timesteps of block N+1 are pinned to block N's solved values. This replaces the previous hardcoded behavior and fixes incorrect stitching forblock-overlap >= 2.linopy upgraded to >=0.9.0 - Minimum supported Python version now rises to 3.11 accordingly.
Module reorganization -
validate_optim_configmoved fromgems_craft.optim_config.parsingtogems_craft.optim_config.validation. Package-level imports remain unchanged; only direct imports from the parsing module need updating.Removed unused models-design/ folder - Cleaned up drawio diagrams that are no longer referenced.
Fixed
fastthermal heuristic with no minimum power -find_min_generation_fastno longer short-circuits to all-zero output whenmin_power_per_unitis ~0, ensuring unit-commitment information is preserved.Standard library parsing now accepts hybrid port-type fields -
parse_yaml_libraryno longer rejectsarea-connection/thermal-capacity-connectionon port-types.Impact Analysis
Modules affected: optim_config/, simulation/ (thermal heuristics)
Solver output changes: The fix to sequential mode stitching may produce different results for problems using
block-overlap >= 2, as the previous behavior was incorrect. The thermal heuristic fix ensures committed units remain available for production when minimum power is near zero.Checklist
