+intel-microcode (3.20140913.1) unstable; urgency=low
+
+ This release drops support for automatically applying microcode
+ updates without a reboot. The microcode updates can still be applied
+ without a reboot through manual action of the system administrator, at
+ his own risk.
+
+ Microcodes known to be dangerous have been renamed so that they will
+ not be found by the kernel. This is a reactive blacklisting: it is
+ unlikely to be complete at any point in time.
+
+ The 3.x branch of the intel-microcode packages will only support Linux
+ kernels v3.10 and above. For older kernels, you must use the 1.x
+ branch of the intel-microcode packages.
+
+ Refer to /usr/share/doc/intel-microcode/README.Debian for details.

+intel-microcode (1.20130222.3) unstable; urgency=low
+
+ This release adds support for early microcode updates on Linux kernel
+ v3.9 and later. It requires the kernel support for the feature to be
+ compiled in, the use of an initramfs, and also recent versions of the
+ iucode-tool and initramfs-tools packages.
+
+ Early microcode updates greatly reduce the chances of system
+ malfunction due to any issues that are corrected by the microcode
+ update. The microcode will be updated while the kernel initializes
+ the boot processor, and before any other processors (in a multicore
+ system) are enabled.

+intel-microcode (1.20120606.4) unstable; urgency=low
+
+ The initramfs logic to automatically restrict the microcodes that have
+ to be installed using iucode-tool can fail in a very specific situation
+ when the intel-microcode package is installed for the first time at the
+ same time the _currently running_ kernel is being upgraded.
+
+ intel-microcode will warn you should that happen, and will install all
+ microcodes, resulting in a much larger initramfs image than expected.
+
+ If you did hit this failure mode and you believe the large initramfs
+ will cause problems for your system to reboot, please remove the
+ intel-microcode package to reduce the initramfs size, reboot to load
+ the upgraded kernel, and then reinstall the intel-microcode package.
+
+ Once the intel-microcode package is installed, it will cooperate with
+ the kernel packages and automatically avoid the issue on future
+ upgrades.

+intel-microcode (1.20120606.1) unstable; urgency=low
+
+ This major release update changes how Debian handles Intel system
+ processor microcode updates. Initscripts and the old microcode.ctl
+ utility are not used to load microcode anymore.
+
+ Previously, microcode.ctl would be used to read the text file
+ distributed by Intel (microcode.dat), convert it to binary, and upload
+ to /dev/cpu/microcode. This functionality has been deprecated in the
+ kernel upstream for a long time, the firmware loader and a sysfs
+ interface should be used instead.
+
+ The Intel microcode.dat file is now preprocessed using iucode-tool when
+ the intel-microcode package is built, and the resulting binary data
+ files for /lib/firmware/intel-ucode are shipped, ready for use by the
+ kernel.
+
+ The intel-microcode package now provides automation for autoloading
+ microcode from the initramfs, instead of relying on any initscripts.
+ Refer to the README files in /usr/share/ doc/intel-microcode for more
+ details; there is some limited support for /usr/share/misc/
+ intel-microcode.dat files.
+
+ If you don't use an initramfs for a custom-built kernel, please make
+ sure the microcode driver is a module, and to load it at a time
+ /lib/firmware is already available. Adding it to /etc/modules is
+ usually enough. In this specific case, /usr/share/misc/
+ intel-microcode.dat is not supported, refer to the README files for
+ more detail.
+
+ WARNING: if you have an old /usr/share/misc/intel-microcode.dat file,
+ it may cause problems because of the way Intel does microcode release
+ management. As a rule, it is best to remove outdated microcode.dat
+ files from the system.
