Release Notes - Mesos - Version 0.28.0 (WIP)
--------------------------------------------
This release contains:
- * [MESOS-4343] - We have introduced a new cgroups isolator for enabling the net_cls
- subsystem in linux. The cgroups/net_cls isolator allows operators
- to provide network performance isolation and network segmentation
- for containers within a Mesos cluster. To enable the cgroups/net_cls
- isolator, append `cgroups/net_cls` to the `--isolation` flag when
- starting the slave. You can find more details about the isolator in
- the Apache Mesos documentation page for `Mesos containerizer`.
- * [MESOS-2840] - Experimental support for container images in Mesos containerizer
- (a.k.a. Unified Containerizer). This allows frameworks to launch
- Docker/Appc containers using Mesos containerizer without relying on
- docker daemon (engine). The isolation of the containers is done
- using isolators. Please refer to container-image.md for currently
- supported features and limitations.

+
+ * [MESOS-4687] - The implementation of scalar resource values (e.g., "2.5
+ CPUs") has changed. Mesos now reliably supports resources with up to three
+ decimal digits of precision (e.g., "2.501 CPUs"); resources with more than
+ three decimal digits of precision will be rounded. Internally, resource math
+ is now done using a fixed-point format that supports three decimal digits of
+ precision, and then converted to/from floating point for input and output,
+ respectively. Frameworks that do their own resource math and manipulate
+ fractional resources may observe differences in roundoff error and numerical
+ precision.
** API Changes:
* [MESOS-4066] - Agent should not return partial state when a request is made to /state endpoint during recovery.
