1.0.3

• Published on May 5, 2021.
• Fixes: Client.remove() did not accept model by name.
• Fixes: Node names were not escaped when creating new features.
• Fixes: Model.save() failed when format given, but not path.
• Fixes: Model.save() without path given did not save new models.
• Fixes: Model.parameters(evaluate=True) returned strings, not numbers.
• Fixes off-by-one error when passing inner indices to Model.evaluate().
• Comsol expects 1-based indices, as opposed to Python's 0-based indexing.
• Adds missing built-in group 'couplings'.
• mph.start() now returns existing client instance on subsequent calls.

1.0.2

• Published on April 28, 2021.
• Assigns more typical tag names when creating new model features.
• In most cases, tags are now named like they are in the Comsol GUI.
• Node.retag() allows post-hoc modification of a node's tag.
• Adds missing built-in groups, e.g. evaluations and tables.
• Improves performance of node navigation in client–server mode.
• The internal type-casting converts Node instances to their tags.
• The internal type-casting handles lists of numbers.
• Before, property() and create() would only accept lists of strings.
• Node.type() now returns nothing if node has no feature type.
• Moved tutorial model to demos folder.
• Added demo script create_capacitor.py that generates the tutorial model.

1.0.1

• Published on April 23, 2021.
• Fixes failing evaluation when name of default dataset contains slash.
• Fixes failing evaluation of complex-valued expressions.
• Fixes issue with complex numbers in parameter assignments. (#36)

1.0.0

• Published on April 13, 2021.
• We now offer you the best API Comsol has ever seen! 🎉
• See "Creating models: Python style" for a feature demonstration.
• A new Node class allows easy navigation of the model tree.
• The Model class relies internally on Node for most functionality.
• Feature nodes can be created with Model.create().
• Node properties can be read and written via Model.property().
• Feature nodes can be removed with Model.remove().
• The Node class has additional functionality for modifying the model.
• All feature nodes can now be toggled, not just physics features.
• Model.features() and Model.toggle() have been deprecated.
• Use the Node class instead to access that functionality.
• Model.import_() was introduced to supersede Model.load().
• Arguments unit and description to Model.parameter() are deprecated.
• Parameter descriptions should now be accessed via Model.description().
• Model.parameters() now returns a dictionary instead of named tuples.
• This is a breaking change, but in line with other parts of the API.
• mph.start() now picks a random free server port in client-server mode.
• This avoids collisions when starting multiple processes on Linux and macOS.
• Models may be saved as Java, Matlab, or VBA source files.
• mph.tree() helps developers inspect the model tree in the console.
• Known issue: Navigating the model tree is slow in client–server mode.
• It is much faster in stand-alone mode, the default on Windows.
• Made folder search case-insensitive on Linux/macOS, as requested in #31.
• Documentation builds now use the MyST parser and the Furo theme.

0.9.1

• Published on March 24, 2021.
• Added documentation chapter "Demonstrations".
• Added demo script that runs parallel Comsol sessions.
• Amended mph.start() to allow hand-selecting the server port.
• This makes the demo script work reliably on Linux and macOS.
• Improved error handling at server start-up.
• Relaxed log levels during discovery of Comsol installations.
• This suppresses possibly confusing log messages as described in #28.

0.9.0

• Published on March 10, 2021.
• mph.start() is now the preferred way to start a local Comsol session.
• On Windows, it starts a lightweight, stand-alone client.
• On Linux and macOS, it starts a thin client and local server.
• This is due to limitations on these platforms described in issue #8.
• Configuration options are exposed by mph.option().
• An in-memory cache for previously loaded model files may be activated.
• Selection names are returned by model.selections().
• Feature names in physics interfaces are returned by model.features().
• Feature nodes in physics interfaces can be toggled on or off.
• Parameter descriptions can be modified.
• Parameter values may be returned as evaluated numbers instead of string expressions.
• Custom classes derived from Model can now be more easily type-cast to.
• Users are warned if log-in details for the Comsol server have not been set up.
• Fixes issue #23 regarding discovery with older Python versions on Windows.
• Fixes issue #24 regarding localized server output messages.

0.8.2

• Published on February 13, 2021.
• Works around issue of incorrect exit behavior.
• Fixes: Exit code was always 0, even when terminating with sys.exit(2).
• Fixes: Exit code was 0, not 1, when exiting due to unhandled exception.
