v1.4.0

Compare Source

Date: 2024-03-25

This minor release packs a punch both in terms of features, the number of enhancements and bug fixes and perhaps most importantly the addition of a set of tutorials that aim to get novices up-to-speed. The main new feature is a so called EditableTemplate which allows arranging dashboards using a drag-and-drop interface and also has strong integration with JupyterLab previews to go from a notebook to a deployed app without having to worry about writing layout code. Next, this release includes a number of need widgets (NestedSelect, DateRangePicker, ButtonIcon), layouts (Feed) and panes (Textual, WebP), and overhauls the autoreload feature with faster and more robust support for reloading entire modules. Lastly this release, along with Param 2.1.0, continues to build on the new reactive expression API making it easy to write reactive expressions and pipelines including support for streaming data with generators. We really appreciate all the work that went into this release and especially want to call out @​MarcSkovMadsen's effort in putting together the new tutorial materials. There's more work to do but it's a huge step forward and we're excited to hear your feedback. We want to extend a special thanks to our amazing new crop of new contributors including @​atisor73, @​Osuwaidi, @​suryako, @​Davide-sd, @​doraaki, @​mayonnaisecolouredbenz7, @​CTPassion, @​J01024, @​l3ender and @​Coderambling. Next we want to recognize our returning contributors @​vaniisgh, @​cdeil, @​limx0m, and @​TheoMaturin, and the finally the dedicated crew of core contributors which include @​maximelt, @​Hoxbro, @​MarcSkovMadsen, @​ahuang11, @​mattpap and @​philippjfr.
