It's time for the next release of IHP: v20201030 🎉 This release mainly focus on improving existing functionality and making things more stable :) Since the last release we also reached an important milestone: IHP is now the second biggest haskell framework measured by GitHub stars - just 5 months after it's initial public release. The future of haskell web dev is happening right here 🚀

Major Changes

• Improved Schema Designer Error Messages: Possible errors that happen when you run Update DB will now be displayed in a more useful way. Previously the error message just displayed the full postgresql output in a single line. Now the error message is displayed like this:
• Tailwind Documentation: We added documentation on how to integrate tailwindcss into your IHP projects. You can find the guide here: https://ihp.digitallyinduced.com/Guide/tailwindcss.html
• NPM Documentation: We also added a short documentation on how to work with NPM and the JS ecosystem in your IHP projects. You can find the guide here: https://ihp.digitallyinduced.com/Guide/npm.html
• IHP Telemetry: To answer questions like How many people are running at which IHP version? What is the primary OS people are using IHP on? How many active users are working with IHP? we added Telemetry to the local dev server that runs when you call ./start. The dev server reports ihpVersion, os, architecture and a anonymous project id to ihp-telemetry.digitallyinduced.com. You can opt-out by setting a env var IHP_DISABLE_TELEMETRY=1
• Schema Designer: ON DELETE SET DEFAULT: Next to ON DELETE SET NULL you can now use SET DEFAULT.
• Postgres Point Type: You can now use tables that have a POINT column in IHP. The Point type is also supported inside the param functions.

Other Changes

• Old references to ViewContext in the docu have been updated
• The New Migration Generator now automatically creates the Application/Migration directory on first use
• When setLayout is not called inside the application lifecycle IHP will now continue to render a view. Previously it would crash when calling render without a layout.
• Fixed a bug where migration without a description would not be found by the migrate command
• The documentation now has a more visible Next button at the bottom of the first sections.
• Fixed paramOrDefault failing on empty parameters. We also added tests to make sure this won't happen again.
• The IHP version is now displayed when running the dev server in debug mode (DEBUG=1 ./start).
• Some IHP build warnings have been fixed.
• Fixed a regression where the production request logger was not used anymore in production environments by default.
• Removed the error state Cannot start app as postgres is not ready yet. This error cannot happen anymore since we added database pools. Usually when this happens it's usually a false alarm.
