JIRA 4.4 has been released with many new features. There are, however, changes in how custom fields are stored and created that will affect Tempo's “billing key” custom field.

IMPORTANT: DO NOT UPGRADE TO JIRA 4.4 without reading the following:

JIRA custom fields of type “select” store “ids” instead of “values” in JIRA 4.4. The JIRA upgrade process updates all custom fields of type “select” with an associated “id”. The Tempo “billing key” custom field is a kind of “select” field but it should always store the “value” not the “id”. That means that the JIRA 4.4 upgrade process fails on the Tempo “billing key” custom field. Further details here

In order to migrate successfully all of your Tempo data to JIRA 4.4 you need to:

1. Make sure that no version prior to Tempo 6.2.7 is running when the JIRA 4.4 upgrade process runs!
2. Upgrade Tempo to 6.2.7 on your existing JIRA 4.2 – 4.3 (NOTE JIRA 4.0 – 4.1 users must remove the Tempo JAR from their system)
3. Upgrade JIRA 4.4 according to Atlassian instructions with the new Tempo 6.2.7

Tempo 6.2.7 was released 4th August 2011
