Symfony exception pages provide detailed information, such as logs and stack
traces, about the errors that happen during the execution of your applications.
They are immensely useful, but their design was a bit outdated, specially since
we redesigned the toolbar and the profiler in Symfony 2.8.
In Symfony 3.3 we decided to redesign the exception pages to keep displaying
all the information that you need but with a fresh coat of paint. The new design
is based on a big red header with the actionable error message. The rest of the
contents (stack traces, logs, etc.) are displayed on tabs:
This is a better comparison between the existing and the new design:
The new design is highly dynamic, with toggles everywhere, and little features
such as a new favicon to better spot error pages on your browser, a smart code
snippet expanding that always tries to expand your own code first instead of
Symfony or other vendors code, etc.
This redesign was also the perfect excuse to update our cute exception ghost. In
this new design he/she is even happier about your exceptions:
