0.2.0 — 2024-11-14

Added

• Setting versioned = True in a layer definition will now append a
  lock version number to the layer name that automatically increments
  each time the locked requirements change for that layer (layer@1,
  layer@2, etc). (implemented in #24).
• Added documentation for the :ref:stack-specification-format (part of #78).
• Added python_implementation to the published layer metadata (part of #78).
• Added bound_to_implementation to the published layer metadata (part of #78).

Changed

• Enabled rendered previews for documentation PRs (requested in #43).
• Enabled link validity checks when rendering documentation (requested in #62).
• Renamed :class:!EnvironmentExportRequest to :class:LayerExportRequest (part of #33).
• Exposed :class:LayerSpecBase, :class:LayeredSpecBase as public classes (part of #33).
• Exposed :class:LayerEnvBase, :class:LayeredEnvBase as public classes (part of #33).
• Added leading underscores to several private functions and methods (part of #33).
• Added docstrings to all remaining public functions and methods (part of #33).
• Updated docs to actively discourage using @ in layers names (part of #78).
• Renamed fully_versioned_name runtime layer specification field to python_implementation (part of #78).
• Renamed runtime_name to runtime_layer in the layer metadata (to align with the required_layers field),
  and simplified it to always refer to the runtime layer's install target name (part of #78).

Fixed

• Post-installation scripts for layered environments now work
  correctly even when run with a Python installation other
  than the expected base runtime (resolved in #66)
