4.11.1

A new SCons release, 4.11.1, is now available on the SCons download page:

https://scons.org/pages/download.html

Here is a summary of the changes since 4.11.0:

FIXES

• Revert the change to the internal implementation of reading a saved-Variables file. This also undoes the minor API change made when the change was introduced in SCons 4.11.0: in that release is was possible to use a top-relative path in the Variables() call when giving the name of a file (that is, a path that begins with #). This is once again disallowed. The plan is to reintroduce this change in a future release, once the issues are fully resolved.

Thanks to the following contributors listed below for their contributions to this release.

                    Change Log

NOTE: The 4.0.0 release of SCons dropped Python 2.7 support. Use 3.1.2 if Python 2.7 support is required (but note old SCons releases are unsupported). NOTE: Since SCons 4.3.0, Python 3.6.0 or above is required. NOTE: Since SCons 4.9.0, Python 3.7.0 or above is required. NOTE: The last release to support Python 3.7 or Python 3.8 is 4.11.1

RELEASE VERSION/DATE TO BE FILLED IN LATER

From Thaddeus Crews: - ty: Initial support setup within pyproject.toml. - Removed Python 3.7 & 3.8 support.

From William Deegan: - Fix documentation processing to work with lxml 6.1.3 and newer, which no longer resolves external parameter entities by default (lxml LP#2165901). This affects both the SCons documentation build and the docbook tool, which failed on any DocBook source pulling in an external entity module. - Fix the DocBook slides tests on distributions whose docbook-xsl VERSION file carries a non-numeric fm:Version - Debian and Ubuntu ship "snapshot" there for 1.79.2. detectXsltVersion() reported (0, 0, 0), so the tests fed the plain, non-namespaced input to namespace-aware stylesheets and silently produced an empty document. The helper now falls back to the fm:Branch field, which names the XSL-NS branch outright.

From Mats Wichmann: - Reference manual improvements: * Additional clarification for SideEffect()

RELEASE 4.11.1 - Mon, 26 Aug 2026 21:16:00 -0700

From Mats Wichmann: - Undo, for now, the 4.11.0 change (from PR 4875) to read a saved-Variables file using a File node. There were unanticipated side effects not caught by any existing test. Will be reintroduced when the issues can be resolved cleanly without backwards compatibility concerns.

RELEASE 4.11.0 - Mon, 10 Aug 2026 21:16:00 -0700

From Joseph Brill: - Add possible build failure when targeting 32-bit arm using
