Update from 7.7 to 7.8

This document guides you through the update from Camunda BPM 7.7.x to 7.8.0. It covers these use cases:

REST API Date Format

This section is applicable if you use the Camunda engine REST API.

The default date format used in the REST API requests and responses has changed from yyyy-MM-dd'T'HH:mm:ss to yyyy-MM-dd'T'HH:mm:ss.SSSZ (now includes second fractions and timezone). The Camunda webapps support the new format by default.

In case some custom REST clients rely on the old date format, choose one of the two following options:

  1. Update REST clients to use the new format.
  2. Configure custom date format for Camunda REST API (explained in detail in the Custom Date Format) section.
