2.5.12

• Make evaluate handle expressions in which indices have been fixed to integers explicitly (e.g. an epsilon tensor with one index fixed to a number).
• New functionality to update and re-run cells based on the value of a slider, to enable e.g. interactive plots.
• Initial support for numerical solving of ODEs.
• Bug fixes for nevaluate.
• Enable evaluate to figure out index ranges from Integer properties.
• Avoid multiple identically-named notebook files used in import mapping to the same converted .py file.
• Various fixes for hDPI displays to make plots and icons sharp and decorations render at the correct size.
• Scrolling notebook to cell is now smooth.
• (Internal) Remove all dependence on deprecated gtkmm-3.0 features, in preparation of making the notebook build with gtkmm-4.0.
• Add option to hide all input cells (for presentation purposes).
• Add context menu for graphics/plot output to save as SVG.
• Make semicolons more reliably print the expression they terminate.
• Add nintegrate for numerical integration.
• Make nevaluate handle complex-valued expressions.
• Better handling of floating point numbers. All multipliers are now either rationals or doubles.
• New nval function to act as a generic frontend for numerical evaluation of (sub-)expressions (work-in-progress).
• Add safeguards against passing expressions through the SymPy bridge which SymPy cannot (yet) handle.
• Add functionality to drive the notebook via an external script.
• New, more modern Windows installer, which also adds a desktop icon.
• Removed terminal window on Windows.
• Fix export of notebooks to HTML.
• Ubuntu and Fedora packages now available for arm64 in addition to x86_64 architecture.
