? It is recommended to update window patch for solving meltdown/spectre weakness. (weakness description : https://googleprojectzero.blogspot.kr/2018/01/reading-privileged-memory-with-side.html ) ? HJ Model TV F/W : - US/KOR : T-KTM2AKUCB-1020.3 - EU : T-KTM2DEUCB-1000.4 ? The 5th Release ? Notes 1. Because the NPAPI is removed, you don't need to set JAVA Configuration at the begining stage of REACH 4.0. 1-1. When you import TV config or TV software, you should select the zip file instead of folder type on Windows browser. 2. I recommend that after uninstalling REACH 3.1, re-install the latest version of REACH 4.0 instead of update. (But it's ok even if you updated as REACH 4.0 without uninstalling) (If you updated from REACH 4.0 previous version such as 1002.5, you should re-deploy project into TV once in order to use REACH 4.0's feature properly.) 3. Added features : Support Tizen Model(2018) Series : IPv6 Support : Tizen OTA Software Update : TV Software Update Monitoring : EPG Monitoring (To use this feature, Samsung EPG Broker 0.01.037 or highter version must be installed) : AccuWeather translation : Initial Focusing Setting Feature : Message Counter Widget ? Support Browser : Internet Explorer 9 ?, Chrome(recommended), Firefox ? T/S guide : https://wormhole.sec.samsung.net/confluence/display/REAC/Reach+Support ? Caution(IP mode) : Do not deploy TV FW from Server to All TV at once. It can cause issues to Hotel Network Bandwidth and Server's resource. So, please update up to 10 TVs at once.
