# Changelog

## v6.4.3 (2024-08-16)
### Fixed
- Fixed 5G NSA technology detection and carrier selection on ICR-4[12]71 devices
  with Telit FN990.
- Fixed deletion of a backup partition after manufacturing. This may have caused
  manufactured routers to have a wrong initial IP address (192.168.1.101-104).

## v6.4.2 (2024-05-29)
### Added
- Added platform RBv2i-S1 and product ICR-283x-S1. This is a new product in
  development that provides an increased system integrity through secure boot,
  read-only filesystem, dm-verity and configuration hashes.
- Added the `jq` command for a better manipulation of JSON files.
- Added cryptsetup to ICR-2000-S1 routers and to the ltib host utilities used to
  build all platforms. This enables creation and attachment of dm-verity
  protected images.
- Added custom listenig *Port* to the *SSH Configuration*.
- Added highlighing of the *Two-Factor Authentication* menu item on ICR-xxxx-1ND
  routers when the 2FA is not enabled.
### Changed
- Upgraded the Laird SU60 WiFi driver on ICR-3200 routers to version 11.171.0.24.
  This fixes a lot of WiFi connectivity issues on these routers.
- Disabled WiFi WEP encryption on ICR-4100/4200 routers as the Atheros driver
  (ath11k) no longer supports it.
- Hardened the SSH service on ICR-xxxx-1ND routers to meet all requirements of
  the [ssh-audit](https://github.com/jtesta/ssh-audit) tool. Particularly, the
  required RSA key size has been increased to 3072, several insufficiently secure
  ciphers were disabled, and the maximum session timeout was decreased to 900s.
- Modified the filesystem hierarchy for a better compliance with the
  [Filesystem Hierarchy Standard](https://refspecs.linuxfoundation.org/FHS_3.0/fhs-3.0.html):
    - Added `/run` directory for run-time variable data. On all routers (except
      ICR-2000-S1) is this idential to `/var`.
    - Moved `/home/httpd` to `/usr/share/www` and added a symlink to the original
      location to preserve backwards compatibility.
- Modified RouterApp selection to accept filenames corresponding to the current
  platform only, e.g. ICR-4100/4200 routers require names ending with `.v4i.tgz`.
- Enabled CONFIG_TCP_MD5SIG in Linux kernel. This enables the FRR RouterApp to
  set the TCP MD5 option.
- Improved usability of the *Set Real Time Clock* dialog: renamed it to
  *Set Date And Time*, added a radio button to choose between different methods,
  and a quick input validation.
- Upgraded at91bootstrap to version 4.0.8 and U-Boot to version 2021.04 on
  all ICR-2000 routers. This enables secure boot on the ICR-2000-S1 routers.
- Upgraded u-boot-tools used to build all platforms to version 2021.04. This
  enables creation of signed firmware images for ICR-2000-S1.
- Upgraded the ltib's internal popt library to version 1.7. Users that build
  custom `ltib` binaries need to rebuild the RPM database by invoking
  `sudo rm -rf /opt/ltib && rm .lock_file .tc_test_gcc-icr* && ./ltib --hostck`.
### Fixed
- Fixed a crash during the high-volume data upload via cellular on some
  ICR-4100/4200 routers.
- Enabled two-factor authentication on ICR-4100/4200 that was erroneously disabled.
- Fixed an errornous html text displayed when a two-factor authentication failed.
  This occurred only when *Debug* was enabled on *PAM Configuration* page.
- Fixed the *CPU Usage* value in the *System Information* section. The firmware
  erroneously reported the average load instead.
- Fixed an SSH failure after an increase of the key strength requirements.
- Removed broken links to WiFi settings displayed when the WiFi configuration was
  successfully updated but not all APs or STAs were working.

## v6.4.1 (2024-03-27)
### Added
- Added support for WiFi 6 and 6E (802.11ax) on the ICR-4100/4200 platforms. It
  can be enabled by setting *HW Mode* to *IEEE 802.11ax* or *IEEE 802.11ax@6GHz*.
- Added *Module Information* to *WiFi Status* page that indicates chip, firmware
  and a list of supported modes.
- Added ability to *disable external USB Port* on ICR-4400 platforms. This
  increases device security. On ICR-4461-1N is the external USB always disabled.
- Added `net-snmptrap` and `net-snmpinform` commands for sending SNMP v1/v2c/v3
  notifications.
- Added `less` command for an easier command-line maintenance.
- Added `ICR_PLATFORM`, `ICR_COUNTRY` and `ICR_PRODUCT_OID` fields in the
  `/etc/os-release` file. This information is used by some Router Apps.
- Added `.ver` file in the firmware `.bin` tar file for a better identification
  of the firmware file.
- Enabled wakeup after the shutdown due to critical temperature on ICR-4100/4200.
- Added support for Telit FN990 (ICR-4171/4271).
### Changed
- Renamed `version.txt` to `CHANGELOG.md` and changed the format to Markdown,
  based on the https://keepachangelog.com/en/1.1.0/ guidelines.
- Lowered minimum allowed *Lease Time* to 5 seconds for Ethernet and WiFi
  *dynamic DHCP leases* to enable connection of special devices.
  The internal DHCP Client still accepts lease times of at least 20 sec.
- Increased size of the overlay filesystem on ICR-4100/4200 platforms.
- Upgraded dnsmasq to 2.90 to fix CVE-2023-28450 and CVE-2023-50387.
- Upgraded zlib to 1.3.1. This is due to CVE-2023-45853, which does not affect
  our products, but automated scanners were nevertheless unhappy.
### Fixed
- Reclaimed all free space on the root filesystem after firmware upgrade on the
  ICR-4400 platform. After upgrade the partition was shrinked to the installed
  files only. The free space can be reclaimed manually by calling `resize2fs`.
- Fixed detection of the WPA3 encryption in the WiFi scan results. In some cases
  the WPA3 was not detected correctly.
- Fixed filesystem priviledges so the DHCP server can create lease files.
- Fixed online installation of RouterApps to correctly display 100+ items.
- Fixed detection of Ethernet ports in the PPPoE *Interface* configuration. In
  some cases the devices with 2 Ethernet ports offered 3 ports.
- Fixed return code of `/etc/init.d/wifi1 scan` scripts to return 1 on failure.
  This also fixes occasional blank screens in GUI during WiFi scanning.
- Fixed enabling/disabling of *IP Address* and *Subnet Mask / Prefix* in the
  configuration of WiFi STA IPv6.
