Old SkyChart Versions

This SkyChart archive documents software packages that preceded the current release. Its version records include 4.2 and 4.0, compared with 4.2.1 on the main page.

Keeping these records on a dedicated page makes the distinction between historical and current software explicit. It also preserves filenames and platform labels that can be useful when checking an old installation, documenting a migration, or identifying a package retained in an offline archive.

SkyChart Version Archive

SkyChart's historical inventory currently records 31 files and 2 release labels. Those labels are 4.2 and 4.0, with package rows covering 64-bit Linux DEB, RPi 64-bit Linux DEB, RPi 2.3 arm Deb, 32-bit Linux DEB, 32-bit Linux RPM, 64-bit Linux RPM, 64-bit Freebsd tar, and RPi 64-bit Linux tar, plus 14 additional entries.

Among the archived files are skychart_4.2-4046_amd64.deb, skychart_4.2-4046_arm64.deb, skychart_4.2-4046_armhf.deb, skychart_4.2-4046_i386.deb, skychart-4.2-4046.i386.rpm, skychart-4.2-4046.x86_64.rpm, skychart-4.2-4046-FreeBSD_amd64.tar.xz, and skychart-4.2-4046-linux_arm64.tar.bz2, plus 23 additional entries. The package set uses DEB, RPM, TAR.XZ, TAR.BZ2, EXE, ZIP, and DMG formats, providing a practical way to match an old record with the type of package originally distributed.

  • Archived versions: 4.2 and 4.0.
  • Recorded platforms: 64-bit Linux DEB, RPi 64-bit Linux DEB, RPi 2.3 arm Deb, 32-bit Linux DEB, 32-bit Linux RPM, 64-bit Linux RPM, 64-bit Freebsd tar, and RPi 64-bit Linux tar, plus 14 additional entries.
  • Package formats: DEB, RPM, TAR.XZ, TAR.BZ2, EXE, ZIP, and DMG.
  • Stored package records: 31; records with checksums: 31.

Working With Archived SkyChart Releases

The strongest reason to consult an old SkyChart package is reproducibility. A legacy environment may depend on a particular build, packaging method, or operating-system target that has changed in later releases.

Before relying on any archived package, confirm the required version, operating system, architecture, and file type. Release age can also affect security support, dependency availability, file-format behavior, and compatibility with newer hardware or services.

Package and Platform Compatibility

SkyChart packages on this page are labeled for 64-bit Linux DEB, RPi 64-bit Linux DEB, RPi 2.3 arm Deb, 32-bit Linux DEB, 32-bit Linux RPM, 64-bit Linux RPM, 64-bit Freebsd tar, and RPi 64-bit Linux tar, plus 14 additional entries. Match that label with the filename and extension before testing because package format often carries assumptions about the operating system and installation process.

Package extensions in the archive include DEB, RPM, TAR.XZ, TAR.BZ2, EXE, ZIP, and DMG. Use those extensions to separate installable builds from portable archives or platform images, and avoid renaming files in a way that removes useful release-identification details.

Checksums and File Identification

Integrity metadata covers 31 of the 31 listed files and includes MD5, SHA1, and SHA256. This can distinguish an unchanged archived file from one that was renamed, truncated, or otherwise altered after release.

Compare a digest using the same algorithm shown in the package record and require an exact match. If a file has no historical checksum, rely on the official project record and other provenance evidence rather than inventing or inferring a value.

Choosing Between Old and Current Versions

The current SkyChart page lists 4.2.1, while this archive covers 4.2 and 4.0. That separation helps users avoid selecting a historical build when they only intended to find the actively maintained release.

Use the current SkyChart release page for normal evaluation. This archive is the better source only when the target environment, migration plan, or audit record names one of the historical versions listed above.
