- ForeignFunctions has been updated to version 0.5.
- GeometricDecomposability has been updated to version 1.4.2 with minor updates.
- JSON has been updated to version 0.4.
- LieTypes has been updated to version 0.9 with various improvements.

- MultigradedBGG has been updated to version 1.2 with documentation improvements.
- Permutations has been updated to version 1.1, adding several new methods.
- RealRoots has been updated to version 1.1.
- Style has been updated to version 1.1 and now exports a generateGrammar method for generating grammars for syntax highlighting.
- TerraciniLoci has been updated to version 0.3.
- ThinSincereQuivers has been updated to version 0.1 with expanded documentation, fixed typos, and functionality added.
- ToricVectorBundles has been updated to version 1.3 with a bug fix.
- Varieties has been updated to version 0.3.
- Visualize has been updated to version 1.7.
functionality added or improved:
- The profiler has been updated significantly. profile is now a keyword that will accept any Macaulay2 code. Run profileSummary or coverageSummary to view the profiling results.
- The random(QQ) method has been added.
- gcd and lcm now accept a single argument.
- Vector objects belonging to modules of rank 1 may now be added, subtracted, and tested for equality with elements from their underlying rings.
- pairs will now accept any instance of class for which an iterator method is installed.
- applyPairs, scanPairs, and selectPairs will now accept any object that works with pairs.
- vector now accepts a ring as its first argument for constructing elements of free modules.
- format now escapes all control characters in a string.
- It is now possible to write new ... from methods that accept 2 or 3 arguments. See new.
- intersection is now a synonym for intersect.
- directProduct, formerly exported by Polyhedra, has been moved to Core and now accepts any positive number of arguments.
- The sign method has been added.
- Package documentation pages now display BibTeX citation information, provided by cite.
- There now exists a Citation documentation keyword for overriding the default package citation information provided by cite.
- There are now several additional round methods.
- needsPackage will now reload a package if its source has been modified since the last time it was loaded.
- Several new check methods have been added.
- randomSubset has been added for generating random subsets of lists and sets.
functionality changed in a way that could break code:
- The package Divisor has been renamed as WeilDivisors.
- The method isIsomorphism now only returns true or false. To retrieved the computed isomorphism, use the method isomorphism.
- The method Matrix \\ Matrix is now a shortcut for quotient'(Matrix,Matrix). The previous functionality is still available via Matrix // Matrix, which is a shortcut for quotient(Matrix,Matrix). Additionally, both methods now work for maps of non-free modules.
- leadTerm(Ideal) now returns an ideal instead of a matrix.
- gcdCoefficients now returns a sequence instead of a list.
