Website Maintenance (Thu, 30 Jul 2020)
Essential back-end maintenance has been completed to the website today. The changes mainly related to updating security procedures and optimising general performance. Although there should not be many noticeable changes, there have been significant changes to most of the scripts. Whereas a lot of hard work and testing has been done on a local machine before uploading there is no accounting for these changes on a busy live website. If you notice any bugs, then could you please use the following thread at our forum:
Summer break (Fri, 19 Jun 2020)
We hope that Project Euler has contributed to the well-being of its members with so many of us in lockdown during the past few months.
Problem 723 on Sunday 5th July will be the last problem of this remarkable season.
Project Euler will then take a summer break, returning with a new problem on Saturday 5th September, 13:00 UTC.

One Million Members (Wed, 08 Apr 2020)
On Sunday 5 April 2020 the Project Euler membership first exceeded one million members. From humble beginnings, back in 2001, we could never have anticipated how it would have grown to what it has become today. That has only happened because of you, our members, and the team who have worked tirelessly throughout the years to bring high quality problems, week after week.
So this Saturday we will be releasing two problems, one of which will be to celebrate that milestone. Thank you to everyone for being a part of Project Euler and we hope that you continue to enjoy solving the problems for many years to come.(Wednesday 08 April 2020: One Million Members)
