Dear Macaulay2 user,

We are happy to announce the release of Macaulay2, version 1.25.05.  For the list of changes, see https://www.macaulay2.com/doc/Macaulay2/share/doc/Macaulay2/Macaulay2Doc/html/_changes_cm_sp1.25.05.html.

For instructions on installing Macaulay2 or building it from source, please see the wiki at https://github.com/Macaulay2/M2/wiki.

We'll look forward to the next release, version 1.25.11, on November 15.  Beginning in the 1.25.11 release, current routines involving chain complexes and graded modules will be superseded by new functorial homological algebra routines in the Complexes package. Users and package developers are encouraged to preview the upcoming changes by adding HomologicalAlgebraPackage = "Complexes" to their initialization file and reporting any bugs via email or GitHub (https://github.com/Macaulay2/M2/issues/3778).

We are grateful to all the contributors who keep expanding the scope and performance of Macaulay2 via new packages and improvements to the existing code.  You are welcome to submit pull requests at https://github.com/Macaulay2/M2/pulls/.

Please let us know if you have any questions!
