This release brings major improvements to AliECS, including multiple fixes for common error conditions, a refactored environment teardown sequence, a reimplementation of the ODC (EPN subcontrol) client based on the new integration plugin system, and miscellaneous bug fixes.

DEPRECATION NOTICE: starting with AliECS v0.21.0 the o2-aliecs-odc-shim component is deprecated and expected to be removed in the near future. It is still accessible by setting odcshim_enabled to true. The existing variable odc_enabled, which was previously used to enable/disable odc-shim, now controls the new implementation.
