Version 1.25.0

[snehankekre]

Highlights

• Introducing st.toast — a command to briefly show toast messages to users in the bottom-right corner of apps. See our documentation on how to use this feature.

Notable Changes

• st.map now has parameters for latitude, longitude, color, and size to customize data points (#6896).
• st.multiselect supports setting placeholders and specifying the maximum number of selections via the placeholder and max_selections keyword-only arguments, respectively (#6901, #4750). Thanks, @fhiroki!
• Customize the date format for st.date_input with the format parameter (#6974, #5234).
• Forms can now be submitted with Enter/Return while inside st.text_input, st.number_input, or st.text_area (#6911, #3790).
• The app menu icon in the upper-right corner of apps has been changed from “☰” to “⋮” (#6947).

Other Changes

• Minimum required versions increased for multiple Python dependencies, including numpy>=1.19.3 and pandas>=1.3.0 (#6802).
• protobufjs was bumped from 7.2.1 to 7.2.4 (#6959).
• Visual design tweaks to Streamlit’s input widgets (#6944).
• Bug fix: st.slider now accepts general number types like numpy.int64 instead of just int and float (#6816, #6815). Thanks, @milliams!
• Bug fix: Data labels for st.slider and st.select_slider no longer overflow when inside st.expander (#6828, #6297).
• Bug fix: Elements no longer re-render from scratch with each rerun (#6923, #6920).
• Bug fix: st.data_editor hashes styler objects correctly for stability across reruns (#6815, #6898).
• Bug fix: Fixed the padding for embedded apps using st.chat_input to prevent messages being cutoff (#6979).

Love this upgrade
I’ve already implement toast, multiselect placeholders and date_input format in my apps!

Would love to see a similar feature (placeholders) for selectbox too.
I mean, I’m looking for a combo with empty choice and placeholder.

Currently I have this setup:

st.selectbox("Animals", ["", "dog", "cat"])

# looking for something like this
st.selectbox("Animals", ["dog", "cat"], empty=True, placeholder="Choose an animal")

Keep up the awesome work with this magical framework!

Love to see it @Mortafix

You’re more than welcome to submit a feature request on Streamlit’s GitHub repo if there isn’t already one.

It’s definitely on the team’s radar! It’s on the roadmap for next quarter.

Setting None as initial widget value
Allows you to initialize st.selectbox, st.date_input, and other widgets without a value.

In the st.selectbox documentation there’s a little hint to this:

A future update will allow selectboxes to be empty.

Many thanks!
I read the roadmap before, but I think I missed this details

Can’t wait to see more

When will this be pushed to Conda Forge? 1.24 was pushed out pretty quickly.

It looks like there were some technical difficulties but that it is published on conda-forge now.
