The empty inside release

This release adds an :empty pseudo-class which matches widgets with no children. You could use this to hide a container that doesn't have any children, for example:

.container:empty {
    display: none;
}

Also in this release, support for scrolling left and right via the trackpad or a mouse that supports it. This was a contribution from @fancidev

Full changes below:

The appended release

A hotfix. See below for details.

[5.0.1] - 2025-07-25

Fixed

• Fixed appending to Markdown widgets that were constructed with an existing document #5990

The Tabled release.

This is quite a large release! Fueled in part by my work on Toad

Markdown rendering has been improved, with full text selection, prettier code blocks and tables. Plus streaming support.

Plenty of other fixes and additions. Thats to everyone who contributed code and issues!

There are two breaking changes (see below). These are unlikely to affect anyone, but Semver requires bumping the major version number.

[5.0.0] - 2025-07-25

Added

• Added get_minimal_width to Visual protocol #5962
• Added expand and shrink attributes to GridLayout #5962
• Added Markdown.get_stream #5966
• Added textual.highlight module for syntax highlighting #5966
• Added MessagePump.wait_for_refresh method #5966
• Added Widget.container_scroll_offset e84600c
• Added Markdown.source attribute to MarkdownBlocks e84600c
• Added extension mechanism to Markdown e84600c
• Added index to ListView.Selected event #5973
• Added layout switch to Static.update #5973

Fixed

• Fixed TextArea issue with the css theme, where the background color was stuck from the previous theme #5964

Changed

• Improved rendering of Markdown tables (replace Rich table with grid) which allows text selection #5962
• Change look of command palette, to drop accented borders #5966
• Some style tweaks to Markdown e84600c
• Content markup can now accept component classes when preceded by a dot, e.g. "Hello [.my_custo_style]World[/]!" #5981
• Breaking change: Visual.render_strips has a new signature. If you aren't explicitly building Visuals then this won't effect you. #5981
• Breaking change: The component classes on Markdown have been moved to MarkdownBlock. This won't affect you unless you have customize the Markdown CSS #5981
• The textual-speedups library will now be imported automatically if it is installed. Set TEXTUAL_SPEEDUPS=0 to disable.

The Streaming Release

The highlight of this release is the new Markdown.append method which can be used to efficiently stream markdown content (like you might get from an LLM).

Screen.Recording.2025-07-12.at.10.46.30.mov

The Widget.anchor method has changed semantics (and also works much better), which is the reason for the major version bump. This will only impact you if you are actually using that method.

And there are a few fixes and additions. Thanks to the community for these contributions.

[4.0.0] - 2025-07-12

Fixed

• Fixed query_one and query_exactly_one not raising documented WrongType exception. #5945
• Fixed logging to a file on Windows #5941
• Fixed eight bit colors crashing when applying dim style #5957

Changed

• Breaking change: Widget.anchor now has different semantics. It should be applied to a container and anchors to the bottom of the scroll position. #5950

Added

• Added Markdown.append #5950
• Added Widget.release_anchor #5950
• Added compact parameter to MaskedInput #5952

The Selective Release

A hotfix for text selection with soft wrapping in the TextArea widget

[3.7.1] - 2025-07-09

Fixed

• Fixed broken text selection with soft_wrap=False #5940

The Lucky number Sevens release

A few enhancements, including a handy getters module for creating properties to get widgets.

Also a potentially breaking change, see below for the details...

[3.7.0] - 2025-07-07

Added

• Added textual.getters #5930
• Added a show_cursor boolean to TextArea #5934

Changed

• Potential breaking change: Changed default query_one and query_exactly_one search to breadth first #5930
• Cursor is now visible by default when in read only mode (restoring pre 3.6.0 behavior) #5934

Fixed

• Fixed issue with Keylines not scrolling #5936

The belated birthday release

Some substantial optimizations and tweaks for the TextArea widget, and the usual fixes.

[3.6.0] - 2025-07-06

Fixed

• Fixed issue with the "transparent" CSS value not being transparent when set using python #5890
• Fixed issue with pushing screens when Input has mouse captured #5900
• Implemented workaround for Ghostty bug which produces negative mouse coordinates #5926

Changed

• Widget.release_mouse will now only release the mouse, if it was captured by self #5900
• Some optimizations to TextArea, which may be noticeable during scrolling (note: may break snapshots with a TextArea) #5925
• Selecting in the TextArea now hides the cursor until you release the mouse #5925
• Read only TextAreas will no longer display a cursor #5925

Added

• Added TextArea.highlight_cursor_line toggle #5924

The faster startup release

This release contains some optimizations to startup time, which may be significant if you create a lot of widgets. There are also some visual updates to Markdown.

This release will break your snapshots, although I don't expect any visual changes. If you are using the snapshot plugin, you will need to regenerate those snapshots. Even if you give them a quick scan, this should only take a few minutes.

[3.5.0] - 2025-06-20

Changed

• Optimized startup #5869
• New blank visual which makes background faster to render (note this will break snapshots tests this version) #5869
• Exposed code_indent_guides boolean on Markdown widget #5874
• Changed code fence background to use CSS background rather than its code theme #5874

The lenient release

Mostly fixes, although there is a notable change to markup.

Previously anything in square brackets was considered a tag, which resulted in markup errors with Python list literals. i.e. [1,2,3] would be interpreted as a tag. The Content markup parser has been made more lenient in these cases, and treats them as literal text.

[3.4.0] - 2025-06-14

Fixed

• Fixed issues with initial flicker in TextArea rendering https://github.com/Textualize/textual/issues/5841vcomm
• Fixed issue with workers that have large parameter lists breaking dev tools #5850
• Fixed post_message failing on 3.8 #5848
• Fixed log not working from threads #5863

Added

• Added experimental opt-in support for https://github.com/willmcgugan/textual-speedups

Changed

• Content markup is now more lenient; if a 'tag' doesn't contain a valid style it will be included verbatim. #5851

The Community Supported Release

The first community supported release.

Mostly fixes and a few helpful additions. See below for details...

[3.3.0] - 2025-06-01

• Fixed VERTICAL_BREAKPOINTS doesn't work #5785
• Fixed Button allowing text selection #5770
• Fixed running App.run after asyncio.run #5799

Changed

• Added a few features to python -m textual.markup playground #5823
