 # Changelog
 
+## v18.10.3 (upcoming release):
+
+## v18.10.2:
+
+DPDK 18.11 is now supported.
+
+## v18.10.1:
+
+### Packaging
+
+Spec file for creating RPM SPDK packages is now available:
+
+x86_64/spdk
+  Base SPDK package - all apps installed by `make install`
+  - spdk_* applications
+  - shared libs in libs64 dir
+
+x86_64/spdk-devel
+  SPDK development package:
+  - header files
+  - static/shared libs
+
+x86_64/spdk-debuginfo
+x86_64/spdk-debugsource
+  These two are autogenerated by rpmbuild
+
+no_arch/spdk-tools:
+  SPDK tools package:
+    scripts/rpc.py -> /usr/sbin/spdk-rpc
+    scripts/spdkcli.py -> /usr/sbin/spdk-cli
+
+no_arch/spdk-doc: optional, generated when adding '--with doc'
+  SPDK html doc package:
+    doc/output/html/ -> /usr/share/doc/spdk/html
+
+### bdev
+
+On shutdown, bdev unregister now proceeds in top-down fashion, with
+claimed bdevs skipped (these will be unregistered later, when virtual
+bdev built on top of the respective base bdev unclaims it). This
+allows virtual bdevs to be shut down cleanly as opposed to the
+previous behavior that didn't differentiate between hotremove and
+planned shutdown.
+
+### Bug fixes
+
+- nvmf: improve error handling during disconnect and QP shutdown
+- blobstore: remove snpashot from the list only on blob deletion
+- memory: return first translation from mem_map_translate
+- iSCSI: prevent recalculation of CRC multiple times
+- bdev/crypto: improve error handling when creating and unregistering
+- env_dpdk/memory: fix contiguous memory calculation for unaligned buffers
+- env_dpdk/memory: prevent freeing dynamically allocated memory back to OS
+- fio_plugin: Perform initialization and teardown on consistent thread
+- fio_plugin: exit immediately if spdk_fio_init_env fails
+- app/trace: fix app_name dereference on init
+
