Release notes
=============
.. _release_notes_v3_1:
Release 3.1
-----------
This rapid follow-up to Corda 3.0 corrects an issue discovered by some users of Spring Boot and a number of other
smaller issues discovered post release. All users are recommended to upgrade.
Special Thanks
~~~~~~~~~~~~~~
Without passionate and engaged users Corda would be all the poorer. As such, we are extremely grateful to
`Bret Lichtenwald <https://github.com/bret540>`_ for helping nail down a reproducible test case for the
Spring Boot issue.
Major Bug Fixes
~~~~~~~~~~~~~~~
* **Corda Serialization fails with "Unknown constant pool tag"**
This issue is most often seen when running a CorDapp with a Rest API using / provided by ``Spring Boot``.
The fundamental cause was ``Corda 3.0`` shipping with an out of date dependency for the
`fast-classpath-scanner <https://github.com/lukehutch/fast-classpath-scanner>`_ library, where the manifesting
bug was already fixed in a released version newer than our dependant one. In response, we've updated our dependent
version to one including that bug fix.
* **Corda Versioning**
Those eagle eyed amongst you will have noticed for the 3.0 release we altered the versioning scheme from that used by previous Corda
releases (1.0.0, 2.0.0, etc) with the addition of an prepended product name, resulting in ``corda-3.0``. The reason for this was so
that developers could clearly distinguish between the base open source platform and any distributions based on on Corda that may
be shipped in the future (including from R3), However, we have heard the complaints and feel the pain that's caused by various
tools not coping well with this change. As such, from now on the versioning scheme will be inverted, with this release being ``3.1-corda``.
As to those curious as to why we dropped the patch number from the version string, the reason is very simple: there won't
be any patches applied to a release of Corda. Either a release will be a collection of bug fixes and non API breaking
changes, thus eliciting a minor version bump as with this release, or major functional changes or API additions and warrant
a major version bump. Thus, rather than leave a dangling ``.0`` patch version on every release we've just dropped it. In the
case where a major security flaw needed addressing, for example, then that would generate a release of a new minor version.
