# v5.1.0 - November 18th, 2019
We are very happy to announce that eXist-db 5.1.0 has been released.
5.1.0 is a minor release, and as such should be 100% API compatible with 5.0.0. Whilst this is a fairly conservative release, it fixes two critical issues:
1. A security issue, whereby lesser priviledged users were incorrectly granted access to descendant collections [#3059](https://github.com/eXist-db/exist/pull/3059). This bug is present in both eXist-db 4.7.1 (and older) and 5.0.0, and we strongly recommend upgrading.
2. We fixed a Race Condition in the Lock Allocation Table (`WeakLazyStripes`) where under high-load the Garabage Collection of the old Locks would interfere with the creation of new locks. This isssue is present in eXist-db 5.0.0 but not 4.7.1. This issue could cause a 5.0.0 system to throw unexpected exceptions or lock-up.
