Releasesby Glyphpy-shiny shiny 1.6.4
Bug fixes Fixed a path-traversal vulnerability in bookmark restore (CWE-22). Introduced in 1.4.0. Reported by @0xRenSec. When bookmarked state cannot be restored, the notification shown in the client is now a generic message. The reason is logged server-side as a warning on the shiny.bookmark._restore_state logger, so app authors can still see it. (1d8ecb46)

shiny 1.7.0
New features Added test mode, enabled via the SHINY_TESTMODE=1 environment variable or the App(test_mode=) argument (which defaults to that env var). The pytest app-launch fixtures (local_app, create_app_fixture) now run apps in test mode.
shiny 1.8.0
Deprecations ui.output_text_verbatim() is deprecated and now emits a ShinyDeprecationWarning. Please use ui.output_code() / @render.code to create an output container for code (monospaced text), or ui.output_text() / @render.text to create an output container for plain text.
shiny 1.6.3
New features session.destroy() now accepts an optional module id. The parent that inserted a module's UI under an id can tear down that module's scope with session.destroy(id), without the module having to hand back a cleanup handle. Added the brite theme preset, available wherever Shiny theme presets are accepted (e.g. ui.Theme() and ui.page_(theme=)).
shiny 1.6.2
Bug fixes Adapted py-shiny to the htmltools 0.7.0 sibling-classes refactor. No runtime behavior change. Bumped lodash/lodash-es to 4.18.1 in the js-react template lockfile for CVE-2025-13465. Fixed render.DataGrid() column headers and hovered rows not adapting to dark mode when ui.input_dark_mode() is enabled.

Breaking changes OpenTelemetry reactive_update spans now follow each session's cycle: one span per session, from when the session turns busy until all of its effects (including async ones) have finished, carrying the session's session.id. The session's calc, effect, and output spans are its children.
shiny 1.6.0
OpenTelemetry Added the SHINY_OTEL_COLLECT environment variable to set the default collection level globally. Available levels: "none" - Disables all Shiny-specific telemetry collection. Use this for sensitive operations where you don't want Shiny to emit any spans or logs.
shiny 1.5.1
New features - Added toast notification system with ui.toast(), ui.toast_header(), ui.show_toast(), and ui.hide_toast(). Toast notifications are temporary, non-intrusive messages that support multiple semantic types (success, warning, error, etc.), flexible positioning (9 positions: top/middle/bottom × left/center/right), auto-hide with configurable...
