Liferay 7 + MySql 5.5.44 not support -

-

i downloaded liferay 7 (liferay-portal-7.0-ce-ga1) on ubuntu 14.04 when try connect mysql db, :then found error inthat: liferay7 not support lesser mysql 5.6.4. i've installed mysql 5.5.44 on environment. on earlier version of mysql i.e. 5.5.44 other portals running perfectly.

here logs, 

01:43:13,809 info  [elasticsearch[jade dragon][clusterservice#updatetask][t#1]][metadata:317] [jade dragon] [liferay-0] update_mapping [liferaydocumenttype]      __    ____________________  _____  __    / /   /  _/ ____/ ____/ __ \/   \ \/ /   / /    / // /_  / __/ / /_/ / /| |\  /  / /____/ // __/ / /___/ _, _/ ___ |/ / /_____/___/_/   /_____/_/ |_/_/  |_/_/  starting liferay portal community edition 7.0.0 ce ga1 (wilberforce / build 7000 / march 31, 2016)  01:43:18,624 info  [localhost-startstop-1][startupaction:110] there no patches installed 01:43:18,760 error [localhost-startstop-1][startupaction:169] please upgrade @ least mysql 5.6.4. portal no longer supports older versions of mysql.

i've queries:

  • is there fix available except upgrading entire mysql?
  • why liferay 7 not supporting earlier versions of mysql, reason behind that?

why?

new releases of software typically use newer dependencies. it's quite work support older software, 1 typically happy support latest version (and you'd want latest version supported, right?)

liferay 7 requires java8, came in during last days of beta cycle - because every application server it's running on support java8. if wouldn't happen, you'd tied past forever.

is there option?

i assume you'd able implement adapter older mysql versions (and contribute community) - i'm aware there's implementing ce support oracle , sql server (these supported commercial offering only)
