=== Redberry 1.1.9 release===
==New features:==
* $D$-dimensional Dirac algebra (see e.g. [[documentation:ref:DiracTrace]])
* New transformation for Dirac algebra: [[documentation:ref:DiracSimplify]], [[documentation:ref:DiracOrder]] and [[documentation:ref:SpinorsSimplify]]
* [[documentation:ref:setMandelstam5]]: generalised mandelstam variables for $2 \to 3$ processes
* Improved behaviour of [[documentation:ref:DiracTrace]]
* New featured transformation: [[documentation:ref:ExpandTensors]]
* Sugar: [[documentation:ref:InvertIndices]], [[documentation:ref:fullysymmetrize]], [[documentation:ref:fullyantisymmetrize]] and ''Identity'' transformations
==Minor things:==
* Several bugfixes (including [[http://youtrack.redberry.cc/issue/CORE-179|#CORE-179]]) and performance improvements
* Output style for ''WolframMathematica'' [[documentation:ref:outputformat|OutputFormat]] changes: now ''a^b'' instead of ''Power[a, b]''
* Added ''Quiet'' block (suppresses all exceptions and output): ''Quiet { 1/0 }''
* Get index by type ''t.indices[1, LatinUpper]'' will give first Latin capital index
