 %changelog
+* Sat May  7 2011 Jens Petersen <petersen@redhat.com> - 0.10.53-1
+- backport ghc-deps.sh rpm dependency script for automatic versioned
+  library dependencies (without hashes)
+- drop ghc_pkg_deps from ghc_package_devel and ghc_package_prof since
+  ghc-deps.sh generates better inter-package dependencies already
+
 * Wed Mar 16 2011 Jens Petersen <petersen@redhat.com> - 0.10.52-1
 - backport ghc fixes and secondary arch support from 0.11.12:
 - add ghc_pkg_obsoletes to binlib base lib package too
