Patch release to correctly handle regexp-characters ([]{}?^) in filter()
and better handling of the logging-configuration.
Patch release to explicitly include the requests dependency, which was dropped from ixmp4 with release 0.8.1.
- Direct integration with ixmp4 platforms hosted by IIASA
- More flexible and intuitive signature for data validation and categorization

Bumped minimum version of pandas and numpy to fit ixmp4's requirement.

- Use ixmp4 as dependency for better integration with the IIASA Scenario Explorer database infrastructure
- Refactor the "exclude"-column for validation as own attribute (instead of a column in
meta) - Implement a cleaner package structure and reduce exposure of internal methods/modules
Support for Python 3.7-3.9 was removed due to an incompatible dependency.
PR #766 added the ixmp4 package for better integration with the IIASA scenario database infrastructure.
Credentials to access the IIASA scenario database infrastructure should now be managed using the ixmp4 package (see here).
The column exclude of the meta indicators was moved to a new attribute exclude.
All validation methods are refactored such that the argument exclude_on_fail changes
this new attribute (see PR #759).
The term "exclude" is now an illegal column for (timeseries) data and meta indicators.
When importing an xlsx file created with pyam < 2.0, which has an "exclude" column in
the "meta" sheet, the column is moved to the new exclude attribute with a log message.
PR #764 implemented a more restrictive
approach to exposing pyam-internals at the package level, requiring a more explicit
import of these methods. For example, use pyam.utils.to_list()
instead of pyam.to_list().
PR #773 removed the map_regions()
method. This feature is now implemented via the nomenclature.RegionProcessor class.

map_regions()and default mappings csv - #772 Show all missing rows for

Following a change of the UNFCCC data inventory API (see
pik-primap/unfccc_di_api#39),
PR #647 updated the dependencies
to require unfccc-di-api>=3.0.1.
PR #598 added support for
mixed time-domains, i.e., where the time column has both integer and datetime items.
As part of the changes, filtering an IamDataFrame with yearly data using arguments
that are only relevant for the datetime-domain (e.g., month, hour, time) returns
an empty IamDataFrame. Previously, this raised an error.
