+zfs-linux (0.8.3-1) unstable; urgency=medium
+
+  The SIMD acceleration has been fixed in this upstream release.
+  Users could use the following two commands to double check:
+
+    $ cat /sys/module/zfs/parameters/zfs_vdev_raidz_impl 
+    $ cat /sys/module/zcommon/parameters/zfs_fletcher_4_impl
+
+  Another notable change is the parallelization of the KABI checks
+  during the configure stage, which may significantly boost the
+  postinst stage of zfs-dkms that builds the kernel module.

+zfs-linux (0.8.0-1) experimental; urgency=medium
+
+  ZFS 0.8.0 introduced the following NEW features:
+
+    * Native encryption
+    * Raw encrypted 'zfs send/receive'
+    * Device removal
+    * Pool checkpoints
+    * Pool TRIM
+    * Pool initialization
+    * Project accounting and quota
+    * Channel programs
+    * Pyzfs
+    * Python 3 compatibility
+    * Direct IO
+
+  And the following performance improvements:
+
+    * Sequential scrub and resilver
+    * Allocation classes
+    * Administrative commands
+    * Parallel allocation
+    * Deferred resilvers
+    * ZFS Intent Log (ZIL)
+    * Volumes
+    * QAT
+
+  Details about the features and performance improvements can be found at:
+
+    https://github.com/zfsonlinux/zfs/releases/tag/zfs-0.8.0
+
+  NEWS on the Debian packaging side:
+
+    * ZFS doesn't depend on the spl-dkms package anymore, because
+      upstream had merged SPL source into ZFS source tree, and that
+      module is now included in the zfs-dkms package.

+zfs-linux for Debian
+====================
+
+1. Feature flags are enabled by default.
+----------------------------------------
+
+This means that ZoL will now create pools in a way that is
+incompatible with Solaris. If you need Solaris compatibility,
+then create pools like this:
+
+  # zpool create -o version=28 tank ...
+
+ZoL remains compatible with all other ZFS implementations derived
+from Illumos.

+ -- Aron Xu <[email protected]>  Sat, 3 Aug 2013 03:23:11 +0800
+
+2. Use zfs-initramfs with caution.
+----------------------------------
+
+Debian Installer does not support root installation because zfs udeb
+modules are not built in-tree with the linux kernel, and zfs-initramfs
+is included here for people interested to setup ZFS as rootfs manually.
+Since faulty operation on filesystem can lead to major loss of data,
+please use zfs-initramfs with caution.
+
+ -- Aron Xu <[email protected]>  Sat, 3 Aug 2013 03:23:11 +0800
+
+3. Per-zpool config for the periodic-{scrub,trim} cron jobs is supported.
+-------------------------------------------------------------------------
+
+ Starting with 2.0.3-3, the auto-scrub and auto-trim cron jobs will use the
+ "org.debian:periodic-{scrub,trim}" user properties on the pool's root dataset
+ to determine if they should do anything; accepted values are:
+
+	* "auto"    ‒ same as unset, use default checks
+	* "enable"  ‒ always scrub/trim automatically
+	* "disable" ‒ never scrub/trim automatically
+
+ [ Periodic Scrubbing ]
+
+ Scrubbing storage pool data is a routine maintenance operation that check all
+ data against known checksums, and fix early problems like bit riots. This
+ operation is scheduled with low priority in the background, and usually does
+ not have big impact on performance when the pool is not heavily utilized.
+
+ If you would like to scrub all pools periodically, no operation is required
+ as periodic scrub is already the default behavior. Or if you want to
+ make it explicit for a zpool named "tank":
+
+  # zfs set org.debian:periodic-scrub=auto tank
+
+ By default scrub jobs are scheduled on every second Sunday of month.
+
+ [ Periodic Trimming ]
+
+ Some SSD devices require proper scheduling of TRIM commands to maintain best
+ performance. Currently the auto-trim will only trim if the zpool consists of
+ /only/ NVMe drives, since some SATA 2 and SATA 3.0 SSDs will hang or crash
+ during large TRIMs (See #983086). If your zpools with SATA SSDs had no
+ problems trimming before, you will need to run the following command to
+ restore the previous behaviour (always trim a pool):
+
+  # zfs set org.debian:periodic-trim=enable sata-pool
+
+ TRIM jobs are scheduled on every first Sunday of month by default.

+zfs-linux for Debian
+
+Using DKMS is the recommended way of installing this kernel
+module, however if you do have the need of building deb/udeb
+packages containing the binary kernel module, here is the way.
+Be careful when proceed with this way, as your attention is 
+required when kernel ABI get changed on target system that this
+module needs to be rebuilt and it needs to replace the originally
+installed package with this newly built one on target system.
+
+You may first install all required build dependency on a machine
+that runs the very same kernel as on your target system, then
+execute following command at the top level directory of the
+decompressed debian source package. Do not install the generated 
+package with kernels that have different configuration, which is
+not supported and likely to break things.
+
+  * deb packages:
+    fakeroot debian/rules override_dh_binary-modules
+  * udeb packages:
+    fakeroot debian/rules override_dh_binary-modules-udeb
+
+udeb packages for libraries and utilities are not generated by
+default, if you need them then rebuild this package passing the
+variable BUILD_UDEB=true.
+
+zfs-initramfs is built on linux-any to avoid un-wanted installation
+on non-linux architectures that do not need it.
