SpeedCrunch 1.0 released

SpeedCrunch 1.0 is available now for Windows, with installer and portable ZIP packages, and for macOS, with an Apple Silicon-only DMG. We hope to have an official 1.0 package on Flathub soon for Linux users.

Before upgrading: back up any sessions you want to keep.

This version introduces a completely new session system and file format, so sessions from previous releases won't be loaded. In your current version, use Session > Save to keep a backup, and Session > Export > Plain text to save a readable copy of your calculations. You can then recreate your sessions in 1.0 by pasting the expressions into the editor. See the session export instructions for details.

The unit syntax has also changed. Units now go in square brackets, for example 10[m], so expressions using the old syntax will need adjusting.

You can find a summary of the main changes since version 0.12, released in 2016, on the download page.

A few highlights:

• Keep multiple sessions open across tabs, split panes and separate windows.
• Sessions are saved automatically and easy to back up.
• Edit an earlier calculation and recalculate all the expressions below it.
• Work with lists and matrices, with new statistics and linear algebra functions.
• Use a much improved unit system.
• View results as fractions or in several formats at once.
• Choose from more built-in themes or create your own.
• A new logo.

This release includes many fixes and features requested over the past 10 years, but it isn't perfect, and development doesn't end here. As more people start using it, the community will no doubt find bugs and suggest improvements. The plan is to release new minor versions (1.1, 1.2, etc.) every 4 to 12 weeks, depending on the app's stability and demand for new features.

For developers and package maintainers: the official Git repository is now hosted on GitHub. The Bitbucket repository is obsolete.

Unfortunately, the entire issue tracking history was lost because Bitbucket did not give a final warning before shutting down its Issues platform. If you previously reported a bug or requested a feature that still needs attention, please submit it again on the GitHub issue tracker or any of our communication channels. Translation corrections are welcome too, as is feedback on any other part of the app.

Thank you to everyone who has contributed over the years, whether through code, translations, bug reports or suggestions.
