Changelog

All notable changes to pyetm are documented here.

[2.0.2] - 23-07-2026

Added

• pyetm now ships a py.typed marker, so type checkers (mypy, pyright) pick up its inline type hints when the package is imported (PEP 561).

Changed

• Partial updates to inputs, sortables, and custom curves no longer fail wholesale on a single invalid entry. Invalid entries are excluded from the API payload while the valid ones are still applied. Excluded custom curves are reported as warnings instead of raising ScenarioError.

Fixed

• Fixed a file-descriptor leak that could exhaust the OS open-file limit (ulimit) when many sessions were created (#205). ETMSession now closes its event loop on close()and can be used as a context manager (with ETMSession(...) as session:).

[2.0.1] - 29-06-2026

Changed

• Capacity tables (electricity_capacities, district_heating_capacities, hydrogen_capacities, network_gas_capacities) are classified as annual exports, not hourly output curves. Fetch them with get_annual_export() / get_annual_exports() instead of get_hourly_curve().

Breaking

• Capacity tables are only available on modern engines (pro). On the stable 2025-01 tag they do not exist; get_annual_export() returns None in that case.
