If I were Takoyaki Mask I would have written a prose but sadly I
am not, so let me tell in brief. Here you are the Ruby 1.8.7’s
most recent update. Mainly bugfixes.
It is worth noting that, though Ruby project experienced license
change recently (from GPLv2 to 2-clause BSDL) and this is the
first time since then to release something, that change do not
reach to already-released versions like 1.8.7, matz said to us.
So you do not have to worry about it. If you are already using
1.8.7, you can continue using it.
Thank you, happy holidays.
