The old version 5.x is in ports now, but with a caveat: you'll not get any security related fixes or another updates at all -- at least if you aren't a paid subscriber.
Since this 5.0.375.127 release was pushed by Google almost two months ago, it is not the most up-to-date, secure release. Only paid
subscribers get those, until enough subscribers fund the full port to
get done, after which all patches are eventually open-sourced within a
year. There will be no security fixes or info for these older releases
in ports as Google doesn't provide that or support them. If you want
the most secure up-to-date browser on FreeBSD, you have to pay for it:
either directly by funding this FreeBSD port of Chromium until it gets
done or indirectly through the Firefox/Opera search deals, that make
sure google is the default option in your search engine listing:
I don't have a problem with paid development, but as I said in the PR it's bad practice for the portstree. Nowadays it's crazy to use a browser, that is out-of-date. Furthermore it doesn't make sense to support "shareware" in the ports. User installing this kind of software don't know that they will not get any security fixes or bugfixes at all.
