Too Long; Didn't Read
The Bitcoin world was surprised when last week, <a href="https://bitcoincore.org/en/2018/09/18/release-0.16.3/" target="_blank">0.16.3 was released</a> to the public and everyone was urged to upgrade as soon as possible. The ostensible reason was that there was a Denial of Service (DoS) vector found in 0.14-0.16.2 that needed patching. <a href="https://bitcoincore.org/en/2018/09/20/notice/" target="_blank">Later on</a>, we found out that there was the possibility of inflation due to the same bug in 0.15-0.16.2.
