<p>Apache SINGA V3.0.0 is released on April 18, 2020. This is the first official
release since SINGA became the first Top-Level Apache project. There are three
major features added in this release.</p>
<p>First, a new Python class <a href="/docs/graph">Module</a> is introduced. New models
(neural networks) can be implemented by inheriting it. The benefit is that SINGA
will create a computational graph at the backend for speed and memory
optimization.</p>
<p>Second, the <a href="/docs/onnx">soonx</a> module is enhanced to support more ONNX
operators. Multiple ONNX models have been tested for training and inference
using SINGA.</p>
<p>Last, communication optimization for <a href="/docs/dist-train">distributed training</a>,
including gradient sparsification and compression. NCCL is integrated as the
communication library.</p>
<p>Please check the <a href="/docs/software-stack">overview page</a> and detailed
<a href="/docs/installation">guides</a>.</p>
