.. project/release-notes.rst: :orphan: Release Notes ############# nGraph is provided as source code, APIs, build scripts, and some binary formats for various Compiler stack configurations and use cases. For downloads formatted as ``.zip`` and ``tar.gz``, see https://github.com/NervanaSystems/ngraph/releases. This page includes additional documentation updates. We are pleased to announce the release of version |version|. Core updates for |version| -------------------------- + PlaidML support + Double-buffering support + Constant folding + Support for static linking + Additional ops + Preliminary static linking support Known issues ~~~~~~~~~~~~ + No PlaidML training support Latest doc updates |version|-doc ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~ + Instructions how to build ``NGRAPH_PLAIDML`` backend added to :doc:`../buildlb`. + Publishing interim version of doc navigation for updates at ngraph.ai + GPU validations: added 5 functional TensorFlow workloads and 4 functional ONNX workloads to :doc:`../frameworks/validated/list`. .. important:: Pre-releases (``-rc-0.*``) have newer features, and are less stable. Changelog on Previous Releases ============================== 0.24 ---- + Fixes reshape sink/swim issue + More ONNX ops + Elementwise divide defaults to Python semantics + GenerateMask seed optional + Graph visualization improvements + Preserve control dependencies in more places + GetOutputElement has single input 0.23 ---- + More ONNX ops + Elementwise divide defaults to Python semantics + GenerateMask seed optional + Document new debug tool + Graph visualization improvements + Note deprecation of MXNet's ``ngraph-mxnet`` PyPI + Note default change to `svg` files for graphs and visualization + Add more prominent tips for contributors who find the doc-contributor-README + Better GSG / Install Guide structure. + Added group edits and new illustrations from PR 2994 to `introduction.rst`. + Ensure ngraph-bridge link in README goes to right place. + Make project `extras` their own subdirectory with index to help organize them. + **Known Issues** - When using TensorFlow\* v1.14.0 with ```ngraph-bridge`` v0.16.0rc0 and CPU backend, we saw notable to severe decreases in throughput in many models. 0.22 ---- + More ONNX ops + Optimizations + Don't reseed RNG on each use + Initial doc and API for IntelGPU backend + DynamicBackend API 0.21 ---- + The offset argument in tensor reads and writes has been removed + Save/load API + More ONNX ops + Better tensor creation + More shape support + Provenance improvements + offset arg for tensor creation is deprecated + static linking support + Initial test of 0.21-doc + Updated ``doc-contributor-README`` for new community-based contributions. + Added instructions on how to test or display the installed nGraph version. + Added instructions on building nGraph bridge (ngraph-bridge). + Updated Backend Developer Guides and ToC structure. + Tested documentation build on Clear Linux OS; it works. + Fixed a few links and redirs affected by filename changes. + Some coding adjustments for options to render math symbols, so they can be documented more clearly and without excessive JS (see replacements.txt). + Consistent filenaming on all BE indexes. + Removed deprecated TensorAPI. 0.20 ---- + Save/load API + More ONNX ops + Better tensor creation + More shape support + Provenance improvements 0.19 ---- + More dynamic shape preparation + Distributed interface factored out + fp16 and bfloat16 types + codegen execution parameterized by context + NodeMap, NodeVector, ParameterVector, ResultVector now vectors - ``node_vector.hpp`` replaced by ``node.hpp`` - ``op/parameter_vector.hpp`` replaced by ``op/parameter.hpp`` - ``op/result_vector.hpp`` replaced by ``op/result.hpp`` + Additional ONNX ops + Add graph visualization tools to doc + Update doxygen to be friendlier to frontends 0.18 ---- + Python formatting issue + mkl-dnn work-around + Event tracing improvements + Gaussian error function + Begin tracking framework node names + ONNX quantization + More fusions 0.17 ---- + Allow negative padding in more places + Add code generation for some quantized ops + Preliminary dynamic shape support + initial distributed ops + Pad op takes CoordinateDiff instead of Shape pad values to allow for negative padding. 0.16 ---- + NodeInput and NodeOutput classes prepare for simplifications of Node + Test improvements + Additional quantization ops + Performance improvements + Fix memory leak + Concat optimization + Doc updates
