What LibreOffice does
LibreOffice 26.2.5 is the recorded July maintenance release for Windows, macOS and Linux. The Document Foundation has since released 26.2.6 and the newer 26.8 branch; use its current download page for a new deployment unless an existing plan specifically requires these older files. This record identifies x86-64 and ARM64 Windows MSI packages, Intel and Apple-silicon macOS DMGs, and x86-64 DEB/RPM archives. Language packs and offline help are separate downloads where required; copying only the main installer does not provide every locale or help package.
Writer, Calc, Impress, Draw, Base, and Math use OpenDocument formats natively and can open and save DOCX, XLSX, and PPTX. Microsoft Office interoperability is not lossless: complex layouts, fonts, VBA macros, embedded objects, formula behavior, conditional formatting, animations, and newer OOXML features can change. Retain source files and test representative documents before migration.
Java is not required for the whole suite, but some Base, JDBC, wizard, and extension functions require a compatible Java runtime. Extensions and macros execute code and need separate provenance and policy review. Core local editing needs no account; extensions, templates, remote documents, collaboration connectors, update checks, and downloads can require network access.
The versioned publisher directories include detached signatures and checksum material. This review did not install any package, verify a signature locally, exercise Java-dependent components, or compare document fidelity.
