streamlit 1.23.1

on Python PyPI

Highlights

• ✂️ Announcing the general availability of st.data_editor, a widget that allows you to edit DataFrames and many other data structures in a table-like UI. Breaking change: the data editor’s representation used in st.session_state was altered. Find out more about the new format in Access edited data.
• ⚙️ Introducing the Column configuration API with a suite of methods to configure the display and editing behavior of st.dataframe and st.data_editor columns (e.g. their title, visibility, type, or format). Keep an eye out for a detailed blog post and in-depth documentation upcoming in the next two weeks.
• 🔌 Learn to use st.experimental_connection to create and manage data connections in your apps with the new Connecting to data docs and video tutorial.

Notable Changes

• 📊 Streamlit now supports Protobuf 4 and Altair 5 (#6215, #6618, #5626, #6622).
• ☎️ st.dataframe and st.data_editor can hide index columns with hide_index, specify the display order of columns with column_order, and disable editing for individual columns with the disabled parameter.
• ⏱️ The ttl parameter in st.cache_data and st.cache_resource accepts formatted strings, so you can simply say ttl="30d", ttl="1h30m" and any other combination of w, d, h, m, s supported by Pandas’s Timedelta constructor (#6560).
• 📂 st.file_uploader now interprets the type parameter more accurately. For example, "jpg" or ".jpg" now accept both "jpg" and "jpeg" extensions. This functionality has also been extended to "mpeg/mpg", "tiff/tif", "html/htm", and "mpeg4/mp4".
• 🤫 The new global.disableWidgetStateDuplicationWarning configuration option allows the silencing of warnings triggered by setting widget default values and keyed session state values concurrently (#3605, #6640). Thanks, @antonAce!
