I found this document in cakephp official site and find out
Long Term Support for v3.x
Bug fixes for 18 months after v4.0.0.
Security fixes for 36 months after v4.0.0 is released.
and v4.0 will be released within 4years
but as you guys know CakePHP 3.1.x becomes end of life and will no longer receive security updates.
so i’m little bit confuse now, plz let me know if you guys know something!
@rrd is correct. Minor versions are only supported until the next minor version is released. One important exception to this, is security fixes (Which will be backported as needed).
You can still use the CookieComponent in 3.5, it hasn’t been removed, and will not be removed until 4.0. Remember, the term deprecated simply means that “This thing will probably be removed in the future, and you should start looking at migrating your code to the replacement. It is still usable until it is removed though!”
