ANTS 2.0.0 Released

[Andrew Clark (arjclark)]

ANTS 2.0.0 is now available.

A major part of this release is to update ANTS to use iris 3.7.1 and as such many other dependencies used by ANTS have also been updated. As a consequence of the dependency updates there are known changes to memory and runtime performance, so job limits may need to be reviewed.

Given the nature of these updates, any branches in progress will need to be rebranched from head of trunk, and KGOs may need to be updated. If you need advice, please contact the MIAO inbox: miao@metoffice.gov.uk.

Thanks to Jonathan Lillis and Katherine Tomkins for their work on upgrading ANTS to iris 3, and to Claudio Sanchez, Paul Earnshaw and Martin Best for testing ANTS at iris 3.

If you are using ANTS or developing ANTS or contrib applications here are a few changes in 2.0.0 to be aware of:

• https://code.metoffice.gov.uk/trac/ancil/ticket/2116 - ANTS now uses iris 3.7.1 and updated versions of many dependencies.
• https://code.metoffice.gov.uk/trac/ancil/ticket/1925 - We have removed the deprecated old saver.
• https://code.metoffice.gov.uk/trac/ancil/ticket/2273 - Warnings are now treated as errors in unit tests.
• https://code.metoffice.gov.uk/trac/ancil/ticket/1924 - There is no longer a default TwoStage horizontal regridding scheme. Similarly to the vertical regridding scheme, the horizontal regridding scheme now needs to be explicitly specified.
• https://code.metoffice.gov.uk/trac/ancil/ticket/2303 - The documentation now uses the more accessible pydata theme.
• https://code.metoffice.gov.uk/trac/ancil/ticket/1838 - A new search algorithm is available for filling missing points. The new K-D tree option is an alternative to the UM spiral search routine.
