- Excel input/output (I/O)
ixmp writes and reads items with more elements than the ~10⁶ row maximum of the Excel data format, by splitting these across multiple sheets.
The I/O code now explicitly checks for situations where the index sets and names for an item are ambiguous; see this example for how to initialize and read these items.
- Updated dependencies
The minimum versions of the following dependencies are increased:
dask 2.14 (for reporting)
- Deprecations and deprecation policy
The following items, marked as deprecated in ixmp 2.0, are removed (PR #254):
$HOME/.local/ixmp/as a configuration location. Configuration files are now placed in the standard
clone(). Use shift_first_model_year, keep_solution, and scenario, respectively.
rixmp.legacy, an earlier version of the R interface that did not use reticulate.
Newly deprecated is:
Starting with ixmp v3.0, arguments and other features marked as deprecated will follow a standard deprecation policy: they will be removed no sooner than the second major release following the release in which they are marked deprecated. For instance, a feature marked deprecated in ixmp version “10.5” would be retained in ixmp versions “11.x”, and removed only in version “12.0” or later.

Support for Python 2.7 is dropped as it has reached end-of-life, meaning no further releases will be made even to fix bugs.
See PEP-0373 and https://python3statement.org.
ixmp users must upgrade to Python 3.
Configuration for ixmp and its storage backends has been streamlined.
See the ref:Configuration section of the documentation for complete details on how to use
ixmp platform add register local and remote databases.
To migrate from pre-2.0 settings:
…pointed to a directory containing database properties (.properties) files.
All Platform configuration is stored in one ixmp configuration file, config.json, and manipulated using the
ixmp platformcommand and subcommands.
Platformconstructor accepts the name of a stored platform configuration.
Different storage backends may accept relative or absolute paths to backend-specific configuration files.
…gave a default backend via a file path.
On the command line, use
ixmp platform add default NAMEto set
NAMEas the default platform.
This platform is loaded when
ixmp.Platform()is called without any arguments.
…pointed to a default local database.
ixmp.configalways contains a platform named ‘local’ that is located below the configuration path, in the directory ‘localdb/default’.
To change the location for this platform, use e.g.:
ixmp platform add local jdbc hsqldb PATH.

ixmp 0.2.0 provides full support for
clone() across platforms (database instances), e.g. from a remote database to a local HSQL database.
IAMC-style timeseries data is better supported, and can be used to store processed results, together with model variables and equations.
