Monthly update: August 2025

I was planning on slowing things down a bit to enjoy the summer, but that changed one day when I accidentally sent out an email with broken links (the URLs were incorrect). Since I was using Thunderbird for email, I searched for an extension that could allow a user to review the links in a draft message and hopefully prevent the mishap that I experienced. I wasn't able to find such an extension for Thunderbird... and so, Check Links was born!

I threw together a functioning prototype in a weekend, and spend the last two weeks polishing it further. The first beta build of Check Links came out last week, and another is due shortly as this new extension for Thunderbird gets closer to version 1.0.

This has caused me to set aside the work that I had planned for a new version of Read Next, but I plan to revisit it when Check Links 1.0 is released.
