The LEDE Community is proud to announce the first release candidate of
the upcoming LEDE 17.01 stable version series. It incorporates thousands
of commits made during the course of the last months and allows us to
refine the code base for the final v17.01.0 version.

With this release, the LEDE development team closes out an intense
effort to modernize many parts of OpenWrt and incorporate many new
modules, packages, and technologies.


Some selected highlights since the OpenWrt Chaos Calmer release are:

  * Linux kernel updated to version 4.4.42 (from 3.18 in Chaos Calmer)
  * Update of essential software:
    * dnsmasq updated to 2.76 (from 2.73 in Chaos Calmer)
    * busybox updated to 1.25.1 (from 1.23.2 in Chaos Calmer)
    * mbedtls version 2.4.0 (updated from polarssl 1.3.14 in Chaos
    * openssl updated to 1.0.2k
  * Improved Security Features
    * Use SHA256 instead of MD5 to validate source code for upstream
    * mbedtls: disable SSLv3 support
    * OpenSSL: disable support for compression, heartbeats, NPN,
      Whirlpool, and J-PAKE
    * Memory Corruption Mitigation Methods
      * gcc -Wformat -Wformat-security
      * User space Stack-Smashing Protection (Regular)
      * Kernel space Stack-Smashing Protection (Regular)
      * buffer-overflows detection (FORTIFY_SOURCE) (Conservative)
      * RELRO protection (Full)
  * Improved Networking Support
    * Smart Queue Management (SQM) minimizes bufferbloat by using the
      cake and fq_codel qdisc's. //[[:docs:howto:sqm|More...]]//
    * Improvements to the WiFi stack eliminating bufferbloat on ath9k,
      mt76 and some ath10k chipsets
    * Airtime fairness scheduler for ath9k to prevent slow stations
      from hogging too much airtime
    * Various stability and regression fixes to the Linux wireless
      stack and ath9k in particular
    * Provide alternative Candela-Tech ath10k-ct driver
  * Updated toolchain
    * musl 1.1.15
    * gcc 5.4.0
    * binutils 2.25.1
  * Platform and Driver Support
    * Lantiq
      * Added redistributable DSL firmware
      * Updated DSL phy drivers
    * Added new targets:tickets
      * apm821xx (AppliedMicro APM821xx)
      * arc770 (Synopsys DesignWare ARC 770D)
      * archs38 (Synopsys DesignWare ARC HS38)
      * armvirt (QEMU ARM Virtual Machine)
      * ipq806x (Qualcomm Atheros IPQ806X)
      * layerscape (NXP Layerscape)
      * zynq (Xilinx Zynq 7000 SoCs)
    * Reorganized x86 target:
      * Drop dedicated Xen DomU target, merged with x86/generic
      * Enable AES-NI support
    * Removed targets:
      * realview, replaced by armvirt
      * ppc44x, disabled due to code brokeness
      * netlogic, dropped due to no available hardware
  * Build system improvements
    * Separation of base system and community feeds to simplify
      distribution of binary package updates
    * Fixes and enhancements in package dependency handling, better
      support for virtual provides
    * Per-device rootfs images to better tune package selection to each
      individual device profile
    * New image build code improving compilation times and simplifying
      device profile declarations
    * New package/.../check make target to run a series of standard
      diagnostics on Makefiles
    * Support for fetching sources using Curl
    * Generate reproducible source tarballs when packing SCM checkouts
  * Image Builder / SDK
    * Rework library bundling to allow for better portability between
      different Linux distributions
    * Add support for building kernel modules using the SDK
  * Added support for a many new routers and boards


Known issues:

  * Available space on devices with only 4MB flash is very low,
    users requiring extra packages might want to consider using the
    image builder to repack custom images

  * The available memory on devices with 16MB RAM might be too low to
    reliably run opkg or sysupgrade operations, especially in
    conjunction with LuCI

  * The source snapshot tarballs produced by Github do not correctly
    compile all packages due to missing Git history information, this
    will be fixed with the next RC

  * The SDK tarballs embed a wrong revision and might report "r0+3043"
    instead of "r3042", this is a cosmetic issue which will get fixed
    with the next RC

  * Any outstanding issues reported at https://bugs.lede-project.org/
