* Partial forwards compatibility

Older versions of some libraries and plugins may work with 2019.1 and higher only if the default space is enabled and such integrations are only used against that space. To make use of other spaces, please upgrade.

However, 2019.1 also carries some breaking changes to the API so care must be taken when upgrading from a prior version that existing integrations are not effected. There is a comprehensive rundown of these changes available in our downloads section.
