v1.12.1

Release notes

Fixes

• Revert "Refactor DC Sensitivity Analysis with Woodbury engine (#1001)" (#1057)

V1.12.0

Important

⚠️ Do NOT use this version.
The DC Sensitivity Analysis refactoring introduces a huge memory consumption which leads to OutOfMemoryErrors.
Use powsybl-open-loadflow 1.12.1 instead.
