What's new in this version
2019-03-25 Bug bounty continues This year's EU-funded bug bounty programme is still running. It was originally scheduled to end on 7th March, but there was money left over in the budget. So while that money lasts, you still have a chance to earn some by finding vulnerabilities in PuTTY 0.71 or the development snapshots! As before, vulnerabilities should be reported through the HackerOne web site in order to qualify for a bounty: if you send reports directly to the PuTTY team in the usual way, then we'll still fix them, but we can't provide money for them. PuTTY 0.71 released PuTTY 0.71 released includes a large number of security fixes, many of which were found by the recent EU-funded HackerOne bug bounty. There are also other security enhancements (side-channel resistance), and a few new features. It's also the first release to be built for Windows on Arm.
