UPGRADING
NEW FEATURES/CHANGES
====================
-Removed dependency on Perl JSON module
---------------------------------------
+LDB no longer a standalone tarball
+----------------------------------
+
+LDB, Samba's LDAP-like local database and the power behind the Samba
+AD DC, is no longer available to build as a distinct tarball, but is
+instead provided as an optional public library.
+
+If you need ldb as a public library, say to build sssd, then use
+ ./configure --private-libraries='!ldb'
-Distributions are advised that the Perl JSON package is no longer
-required by Samba builds that use the imported Heimdal. The build
-instead uses Perl's JSON::PP built into recent perl5 versions.
+This re-integration allows LDB tests to use the Samba's full selftest
+system, including our knownfail infrastructure, and decreases the work
+required during security releases as a coordinated release of the ldb
+tarball is not also required.
-Current lists of packages required by Samba for major distributions
-are found in the bootstrap/generated-dists/ directory of a Samba
-source tree. While there will be some differences - due to features
-chosen by packagers - comparing these lists with the build dependencies
-in a package may locate other dependencies we no longer require.
+This approach has been demonstrated already in Debian, which is already
+building Samba and LDB is this way.
+
+As part of this work, the pyldb-util public library, not known to be
+used by any other software, is made private to Samba.
+
+LDB Module API Python bindings removed
+--------------------------------------
+The LDB Modules API, which we do not promise a stable ABI or API for,
+was wrapped in python in early LDB development. However that wrapping
+never took into account later changes, and so has not worked for a
+number of years. Samba 4.21 and LDB 2.10 removes this unused and
+broken feature.
