FIRMWARE CHANGE HISTORY
-----------------------
Lenovo RackSwitch G7052 Version 8.1.4.0 (Released June 2016)
** changes since release 8.1.3.0 *

Enhancements:
-------------
NONE

Changes:
--------

- Enabled the support for SFTP (Secure File Transfer Protocol) protocol on the switch.
  (48368)

Fixes:
------

- "show access-control group <group #>" would not include  ACL IPV6 128 in the output, even if it 
   were part of  the ACL group.
   (49858)

- The switch’s browser based interface (BBI) was susceptible to security 
  vulnerabilities XSS (stored cross-site scripting) and CSRF (cross-site request forgery).
  The web security policy mechanism  HSTS (HTTP Strict Transport Security) has been 
  implemented on BBI.
  (49409, 49427, 49471)
 
- The switch’s browser based interface (BBI) would fail to honor the 
  “cache-control=no-cache” directive and still cache the pages. The value of the 
  “cache-control” directive has been changed from “no-cache” to “no-store”. 
  (49475)

- A crash would occur when the switch is trying to authenticate users using LDAP, where
  the user group from the LDAP server is wrongly configured with an unsupported object class.
  (47394) 

- Switch could crash when enabling HTTPS protocol, while  the switch were trying
  to connect to the VSI Manager.
  (50435)

- If the switch were booted directly from USB the image signature would not be 
  verified. The image signature would also not be verified if the image were copied
  to the switch flash from USB using the CLI command “usbcopy fromusb” or its 
  equivalent using SNMP or BBI.
  (55780,54813)

- "show ldap-server" command  displays secondary server IP for current LDAP server instead of
   the primary.
   (55372)

- Switch would fail to upload the tech support dump through SNMP with the tftp option.
  In addition, “Bad file ID 0" messages would be displayed on the console.
  (51195)

========================================================================================
Lenovo RackSwitch G7052 Version 8.1.3.0 (Released Feb. 2016)
** changes since release 8.1.2.0 **

Enhancements:
-------------
NONE

Changes:
--------
NONE

Fixes:
------
- Enable NIST SP -800 131a ,an industry wide security standard that implements strong 
  cryptographic cypher policies. 
  (43603)

- The hwMTM variable is added to the SNMP MIB to allow reading of the Machine Type Model 
  of the switch.
  (44107)

- When the reset button is pressed, it could interrupt an I2C transaction and lock up 
  the I2C bus leading to a hang in the desired switch reset. A fix was added to prevent 
  this sequence of events occurring.
  (43168) 

- Using Cisco ACS, version 5.3 and above, to authenticate users with TACACS protocol,
  could lead to the User Interface thread (SSHD,AGR,TNET,CONS) to be suspended forever,
  thereby denying any further authentication with the TACACS protocol.
  (LV307694/7383)

  before their respective output.
  (38125)

Fixes:

- The SNMP Object hwPartNumber (.1.3.6.1.4.1.20301.2.7.18.1.3.1) would 
  return the MTM instead of the hardware part number.
  (37948)

- If the serial number of the switch was changed, the user was prevented from
  successfully installing a new image, and the message 
  “image contains invalid signature”  would be displayed.
  (40638)

- Extended the ability to support Dual Speed 1/10G MMF SFP+  Transceivers.
  (LV311542,LV311078,LV312616)

- The user is incorrectly prompted for "setup configuration" upon login even 
  though configuration had been applied and saved, and the startup

  using NETCONF management protocol.
