v2.0.0

Type	Category	Title	Description	Breaking
![Changed][changed]	Global	Packages migration	Dropped support for pandas 1.x and 2.x; REHO now requires pandas>=3.0.0. Code relying on pre-3.0 pandas semantics (e.g. implicit downcasting, DataFrame.append, old groupby/resample defaults) will need to be updated before upgrading.	🔴
![Changed][changed]	Global	Packages migration	Dropped support for SQLAlchemy 1.x; REHO now requires sqlalchemy>=2.0.0. Any custom code building queries against QBuildingsReader.tables using the 1.x select([...]) style must be updated to the 2.0 select(...) API.	🔴
![Changed][changed]	Global	Packages migration	Raised the minimum Python version from 3.9 to 3.11. Python 3.9 and 3.10 are no longer supported.	🔴
![Changed][changed]	Global	Packages migration	Unpinned numpy (<2.0.0) and geopandas (<1.0.0). Environments now resolve to numpy 2.x / geopandas 1.x by default; code depending on numpy 1.x or geopandas <1.0 behavior may break.	🔴
![Fixed][fixed]	Scripts	Packages migration	Various fixes to example scripts and the test runner for pandas 3.0.	🟢
![Changed][changed]	![Preprocessing][preprocessing]	QBuildings access	QBuildingsReader.read_db selection API changed: 1. Buildings are now selected through a single filters dictionary, e.g. read_db({'transformers': 234}), read_db({'egid': 1009515}), read_db({'geometry': 'boundary.gpkg'}). 2. Filters combine with a logical AND, so a transformer and an EGID can be given together. 3. The district_boundary, district_id, egid, and id_building keyword arguments are deprecated in favor of filters; they now raise a DeprecationWarning and will be removed in a future release.	🟠
![Added][added]	![Preprocessing][preprocessing]	QBuildings access	QBuildingsReader.read_db can now select buildings by id_building, and by an arbitrary geometry (a file path, WKT string, shapely geometry, or (Geo)DataFrame) via spatial intersection.	🟢
![Added][added]	![Plotting][plotting]	Profiles	Adding of a plot_combined_profiles that allows to combine different type of profiles to be mixed together, typically one by season.	🟢
![Fixed][fixed]	![Plotting][plotting]	Plot fixes	Correction in plot_eud and plot_paretoand plot_pareto_by_objectives.	🟢
![Added][added]	![Preprocessing][preprocessing]	Reference scenario	If the scenario name is reference, it activates a function where we build REHO with the units configuration (heating + dhw system and installed PVs) retrieved from QBuildings.	🟢
![Changed][changed]	![Preprocessing][preprocessing]	Solar gains	Change of re-calibration of solar gains and Uh when ERA < Footprint.	🟢
![Changed][changed]	![Postprocessing][postprocessing]	Sensitivity analysis	Add an option to do the sensitivity analysis in the buildings data as well as prices.	🟠

Migration notes

• If you pin REHO<2.0 (once released) in your own project, your existing pandas 1.x/2.x and
  SQLAlchemy 1.x environment will keep working. Upgrading to REHO>=2.0 requires upgrading
  pandas and SQLAlchemy alongside it — there is no dual-support release.
• Replace reader.read_db(district_id=234, egid=[...]) with
  reader.read_db({'transformers': 234, 'egid': [...]}). The deprecated keyword form still works
  but now raises a DeprecationWarning and will be removed later.
