A new tool from Eric Meyer, Brian Kardell, and Stephanie Stimac backed with Igalia’s support. Brian announced it on his blog, as did Eric, describing it like this:
What BCD Watch does is, it grabs releases of the Browser Compatibility Data (BCD) repository that underpins the support tables on MDN and services like caniuse.com. It then analyzes what’s changed since the previous release.
Every Monday, BCD Watch produces two reports. The Weekly Changes Report lists all the changes to BCD that happened in the previous week — what’s been added, removed, or renamed in the whole of BCD. It also tells you which of the Big Three browsers newly support (or dropped support for) each listed feature, along with a progress bar showing how close the feature is to attaining Baseline status.
Browser support data is at MDN. There’s also plenty at Caniuse.com. The two share data, in fact, though not all of it. We now have Baseline, which is also cited in MDN and Caniuse alike. It’s nice to see an effort at cracking a central spot for all this — organized by date, no less.
Oh, and hey, there’s a feed. Even better.
You can also poke at its repo. Thanks a bunch, Eric, Brian, Stephanie, and Igalia! This is super helpful and already part of my toolkit.
