This is a list of features that are scheduled to be removed from dpkg. What: 822-date (program) Status: obsolete When: lenny+1 Warning: program Why: Should switch to use 'date -R'. What: cleanup-info (program) Status: deprecated When: lenny Warning: none Why: This program was needed long time ago to fixup broken info dir files generated by buggy install-info programs. Should not be needed anymore. What: Source-Version (substvar) Status: obsolete When: lenny+1 Warning: lintian (substvar-source-version-is-deprecated) Why: The semantics of Source-Version are missleading when applied to binNMUs. Should switch to use binary:Version or source:Version substvars. What: Revision, Package-Revision, Package_Revision, Class, Recommended, Optional (field) Status: obsolete When: lenny+1 Warning: program Why: These fields have been superseded by either other fields with better names or values in other fields. What: recommended, contrib, base (priority) Status: obsolete When: lenny+1 Warning: none Why: These priorities have been superseded by either other fields or values in other fields. What: --force-auto-install (dpkg option) Status: obsolete When: lenny+1 Warning: program What: --largemem, --smallmem (dpkg option) Status: obsolete When: lenny+1 Warning: program What: --no-auto-select (dpkg option) Status: deprecated When: lenny+1 Warning: none What: -u, --udeb (dpkg-scanpackages option) Status: deprecated When: lenny+1 Warning: none Why: This option has been superseded by -tudeb. What: substvars support in dpkg-source and dpkg-genchanges Status: deprecated When: lenny+1 Warning: program Why: substvars do not make sense during generation of .dsc and .changes files. This also means that it won't be possible anymore to override the Format field output by dpkg-genchanges. What: support of custom changelog parsers understanding only -v Status: obsolete When: lenny+1 Warning: none Why: The debian changelog parser has been enhanced. It supports new options that enable more fine-grained retrieval of information. Those new options will be used by scripts (like dpkg-genchanges). . Custom changelog parsers must be updated to support the new API (see dpkg-parsechangelog(1) and README.api). What: support of PGP Status: deprecated When: lenny+1 Warning: program Why: PGP is not part of Debian and GnuPG has been the standard tool for digital signatures for several years already. Supporting only GnuPG enables us to rely on some of its features.
