Bugfixes (new approach)

From UKCA

The aim of this page is to present the information on the new bug reporting system. All bugs should be reported to ukca_bugs@metoffice.gov.uk. More details of the approach to reporting and fixing bugs is contained in the document here .

Bug fixes table

This is a list of all reported bugs, with a link to tickets with more information on the issue and branches to fix it. Some of the bugs/ issues are described in more detail on an older bugfixes page. The UM versions listed are those where the bug is known to be present. Please note however, that bugs in versions before 8.2 are not reported here, although information on some of these can be found here.

Package branches table

For every supported version, the aim will be to have a package that fixes all bugs known to exist at that UM version. The package will be supported on both the NCAS and Met Office repositories (until a single repository is created)
