How to get Magento 2 latest version number available?

Question

Magento 1 was here: http://connect20.magentocommerce.com/community/Mage_All_Latest/releases.xml

Where is Magento 2?

Answer 1

Since the latest Magento 2 code is published to GitHub (unlike Magento 1), the list of all releases can be found there: https://github.com/magento/magento2/releases

Answer 2

great, if we rely on github releases, then we can create some simple check/variable from:

VERSION=$(curl -s https://api.github.com/repos/magento/magento2/releases 2>&1 | head -36 | grep -E 'tag_name|published_at')

echo "${VERSION}"

"tag_name": "2.0.1",
"published_at": "2016-01-20T14:59:42Z", 

UPDATE: correct way to get the latest version number (cause of magento versioning):

VERSION=$(curl -s https://api.github.com/repos/magento/magento2/tags 2>&1 | head -3 | grep -oP '(?<=")\d.*(?=")')

I prefer this bash command

VERSION_FULL=$(curl --silent "https://api.github.com/repos/magento/magento2/releases/latest" | grep -Po '"tag_name": "\K.*?(?=")')
    
echo $VERSION_FULL
