chore(license): Change license from GPL-3 to MIT (#4339)

* Change license from GPL-3 to MIT

Updated the project license from GPL-3 to MIT in DESCRIPTION, LICENSE, LICENSE.md, README.md, and package.json. Added LICENSE.md with the MIT license text and updated .Rbuildignore to exclude LICENSE.md from builds.

* `npm run build` (GitHub Actions)

* Update LICENSE and add LICENSE.note

Replaced the LICENSE file content with a summary including year and copyright holder. Moved detailed third-party license information to a new LICENSE.note file.

* Remove R check log file

Deleted the ..Rcheck/00check.log file, likely to clean up generated or temporary files from the repository.

 Description: Makes it incredibly easy to build interactive web
     applications with R. Automatic "reactive" binding between inputs and
     outputs and extensive prebuilt widgets make it possible to build
     beautiful, responsive, and powerful applications with minimal effort.

 # shiny (development version)
 
+# shiny 1.12.1
+
+## New features
+
+* `withOtelCollect()` and `localOtelCollect()` temporarily control
+  OpenTelemetry collection levels during reactive expression creation,
+  allowing you to enable or disable telemetry collection for specific modules
+  or sections of code. (#4333)
+
+## Bug fixes and minor improvements
+
+* OpenTelemetry code attributes now include both the preferred attribute names
+  (`code.file.path`, `code.line.number`, `code.column.number`) and the
+  deprecated names (`code.filepath`, `code.lineno`, `code.column`) to follow
+  OpenTelemetry semantic conventions while maintaining backward compatibility.
+  The deprecated names will be removed in a future release after Logfire
+  supports the preferred names. (#4325)
+
+* `ExtendedTask` now captures the OpenTelemetry recording state at
+  initialization time rather than at invocation time, ensuring consistent span
+  recording behavior regardless of runtime configuration changes. (#4334)
+
+* Timer tests are now skipped on CRAN. (#4327)
+
+# shiny 1.12.0

+* Shiny now supports [OpenTelemetry](https://opentelemetry.io/) via
+  [`{otel}`](https://otel.r-lib.org/index.html). By default, if
+  `otel::is_tracing_enabled()` returns `TRUE`, then `{shiny}` records all
+  OpenTelemetry spans. See [`{otelsdk}`'s Collecting Telemetry
+  Data](https://otelsdk.r-lib.org/reference/collecting.html) for more details
+  on configuring OpenTelemetry. (#4269, #4300)
+
+* Supported values for `options(shiny.otel.collect)` (or
+  `Sys.getenv("SHINY_OTEL_COLLECT")`):
+  * `"none"` - No Shiny OpenTelemetry tracing.
+  * `"session"` - Adds session start/end spans.
+  * `"reactive_update"` - Spans for any synchronous/asynchronous reactive
+    update. (Includes `"session"` features).
+  * `"reactivity"` - Spans for all reactive expressions. (Includes
+    `"reactive_update"` features).
+  * `"all"` [default] - All Shiny OpenTelemetry tracing. Currently equivalent
+    to `"reactivity"`.
+
+* OpenTelemetry spans are recorded for:
+  * `session_start`: Wraps the calling of the `server()` function. Also
+    contains HTTP request within the attributes.
+  * `session_end`: Wraps the calling of the `onSessionEnded()` handlers.
+  * `reactive_update`: Signals the start of when Shiny knows something is to
+    be calculated. This span ends when there are no more reactive updates
+    (promises or synchronous) to be calculated.
+  * `reactive`, `observe`, `output`: Captures the calculation (including any
+    async promise chains) of a reactive expression (`reactive()`), an observer
+    (`observe()`), or an output render function (`render*()`).
+  * `reactive debounce`, `reactive throttle`: Captures the calculation
+    (including any async promise chains) of a `debounce()`d or `throttle()`d
+    reactive expression.
+  * `reactiveFileReader`, `reactivePoll`: Captures the calculation
+    (including any async promise chains) of a `reactiveFileReader()` or
+    `reactivePoll()`.
+  * `ExtendedTask`: Captures the calculation (including any async promise
+    chains) of an `ExtendedTask`.
+
+* OpenTelemetry Logs are recorded for:
+  * `Set reactiveVal <name>` - When a `reactiveVal()` is set
+  * `Set reactiveValues <name>$<key>` - When a `reactiveValues()` element is
+    set
+  * Fatal or unhandled errors - When an error occurs that causes the session
+    to end, or when an unhandled error occurs in a reactive context. Contains
+    the error within the attributes. To unsanitize the error message being
+    collected, set `options(shiny.otel.sanitize.errors = FALSE)`.
+  * `Set ExtendedTask <name> <value>` - When an `ExtendedTask`'s respective
+    reactive value (e.g., `status`, `value`, and `error`) is set.
+  * `<ExtendedTask name> add to queue` - When an `ExtendedTask` is added to
+    the task queue.
+
+* All OpenTelemetry logs and spans will contain a `session.id` attribute
+  containing the active session ID.
+
+## New features
+
+* `updateActionButton()` and `updateActionLink()` now accept values other than
+  `shiny::icon()` for the `icon` argument (e.g., `fontawesome::fa()`,
+  `bsicons::bs_icon()`, etc). (#4249)
+
+## Bug fixes and minor improvements
+
+* Showcase mode now uses server-side markdown rendering with the
+  `{commonmark}` package, providing support for GitHub Flavored Markdown
+  features (tables, strikethrough, autolinks, task lists). While most existing
+  README.md files should continue to work as expected, some minor rendering
+  differences may occur due to the change in markdown processor. (#4202,
+  #4201)
+
+* `debounce()`, `reactiveFileReader()`, `reactivePoll()`, `reactiveValues()`,
+  and `throttle()` now attempt to retrieve the assigned name for the default
+  label if the srcref is available. If a value cannot easily be produced, a
+  default label is used instead. (#4269, #4300)
+
+* The default label for items described below will now attempt to retrieve the
+  assigned name if the srcref is available. If a value can not easily be
+  produced, a default label will be used instead. This should improve the
+  OpenTelemetry span labels and the reactlog experience. (#4269, #4300)
+  * `reactiveValues()`, `reactivePoll()`, `reactiveFileReader()`, `debounce()`,
+    `throttle()`, `observe()`
+  * Combinations of `bindEvent()` and `reactive()` / `observe()`
+  * Combination of `bindCache()` and `reactive()`
+
+* `updateActionButton()` and `updateActionLink()` now correctly render HTML
+  content passed to the `label` argument. (#4249)
+
+* `updateSelectizeInput()` no longer creates multiple remove buttons when
+  `options = list(plugins="remove_button")` is used. (#4275)
+
+* `dateRangeInput()`/`updateDateRangeInput()` now correctly considers the time
+  zones of date-time objects (POSIXct) passed to the `start`, `end`, `min` and
+  `max` arguments. (thanks @ismirsehregal, #4318)
+
+## Breaking changes
+
+* The return value of `actionButton()` and `actionLink()` now wraps `label`
+  and `icon` in an additional HTML container element. This allows
+  `updateActionButton()` and `updateActionLink()` to distinguish between the
+  `label` and `icon` when making updates, and allows spacing between `label`
+  and `icon` to be more easily customized via CSS.
+
+# shiny 1.11.1
+
+This is a patch release primarily for addressing the bugs introduced in v1.11.0.
+
+## Bug fixes
+
+* Fixed an issue where `InputBinding` implementations that don't pass a value to their `subscribe` callback were no longer notifying Shiny of input changes. (#4243)
+
+* `updateActionButton()` and `updateActionLink()` once again handle `label` updates correctly. (#4245)
+
+# shiny 1.11.0
+
+## Improvements
+
+* When auto-reload is enabled, Shiny now reloads the entire app when support files, like Shiny modules, additional script files, or web assets, change. To enable auto-reload, call `devmode(TRUE)` to enable Shiny's developer mode, or set `options(shiny.autoreload = TRUE)` to specifically enable auto-reload. You can choose which files are watched for changes with the `shiny.autoreload.pattern` option. (#4184)
+
+* When busy indicators are enabled (i.e., `useBusyIndicators()`), Shiny now:
+    * Shows a spinner on recalculating htmlwidgets that have previously rendered an error (including `req()` and `validate()`). (#4172)
+    * Shows a spinner on `tableOutput()`. (#4172)
+    * Places a minimum height on recalculating outputs so that the spinner is always visible. (#4172)
+
+* Shiny now uses `{cli}` instead of `{crayon}` for rich log messages. (thanks @olivroy, #4170)
+
+* `renderPlot()` was updated to accommodate changes in ggplot2 v4.0.0. (#4226)
+
+* When adding the new tab via `insertTab()` or `bslib::nav_insert()`, the underlying JavaScript no longer renders content twice. (#4179)
+
+## New features
+
+* `textInput()`, `textAreaInput()`, `numericInput()` and `passwordInput()` all gain an `updateOn` option. `updateOn = "change"` is the default and previous behavior, where the input value updates immediately whenever the value changes. With `updateOn = "blur"`, the input value will update only when the text input loses focus or when the user presses Enter (or Cmd/Ctrl + Enter for `textAreaInput()`). (#4183)
+
+* `textAreaInput()` gains a `autoresize` option, which automatically resizes the text area to fit its content. (#4210)
+
+* The family of `update*Input()` functions can now render HTML content passed to the `label` argument (e.g., `updateInputText(label = tags$b("New label"))`). (#3996)
+
+* `ExtendedTask` now catches synchronous values and errors and returns them via `$result()`. Previously, the extended task function was required to always return a promise. This change makes it easier to use `ExtendedTask` with a function that may return early or do some synchronous work before returning a promise. (#4225)
+
+* The `callback` argument of Shiny.js' `InputBinding.subscribe()` method gains support for a value of `"event"`. This makes it possible for an input binding to use event priority when updating the value (i.e., send immediately and always resend, even if the value hasn't changed). (#4211)
+
+## Changes
+
+* Shiny no longer suspends input changes when _any_ `<input type="submit">` or `<button type="submit">` is on the page. Instead, it now only suspends when a `submitButton()` is present. If you have reason for creating a submit button from custom HTML, add a CSS class of `shiny-submit-button` to the button. (#4209)
+
+* Shiny's JavaScript assets are now compiled to ES2021 instead of ES5. (#4066)
+
+* Upgraded jQuery from 3.6.0 to 3.7.1. (#3969)
+
+* Updated jQuery UI from 1.13.2 to 1.14.1. (#4175)
+
+## Bug fixes
+
+* The Shiny Client Console (enabled with `shiny::devmode()`) no longer displays duplicate warning or error message. (#4177)
+
+* Synchronous errors that occur inside a `ExtendedTask` no longer stop the session. (#4225)
+
+* Calling `removeModal()` immediately after `showModal()` no longer fails to remove the modal (this would sometimes happen if the remove message was received while the modal was in the process of being revealed). (#4173)
+
+* `runExample("08_html")` now (correctly) requests to 'shiny.min.css', eliminating a network request failure. (#4220)
+
+* `shiny::shinyAppTemplate()` no longer errors without a call to `library(shiny)`. (#3870)
+
+# shiny 1.10.0
+
 ## New features and improvements
 
-* Added new functions, `useBusyIndicators()` and `busyIndicatorOptions()`, for enabling and customizing busy indication. Busy indicators provide a visual cue to users when the server is busy calculating outputs or otherwise serving requests to the client. When enabled, a spinner is shown on each calculating/recalculating output, and a pulsing banner is shown at the top of the page when the app is otherwise busy. (#4040)
+* When busy indicators are enabled (i.e., `useBusyIndicators()` is in the UI), Shiny now:
+    * Shows the pulse indicator when dynamic UI elements are recalculating and no other spinners are visible in the app. (#4137)
+    * Makes the pulse indicator slightly smaller by default and improves its appearance to better blend with any background. (#4122)
+
+* Improve collection of deep stack traces (stack traces that are tracked across steps in an async promise chain) with `{coro}` async generators such as `{elmer}` chat streams. Previously, Shiny treated each iteration of an async generator as a distinct deep stack, leading to pathologically long stack traces; now, Shiny only keeps/prints unique deep stack trace, discarding duplicates. (#4156)
+
+* Added an example to the `ExtendedTask` documentation. (@daattali #4087)
+
+## Bug fixes
+
+* Fixed a bug in `conditionalPanel()` that would cause the panel to repeatedly show/hide itself when the provided condition was not boolean. (@kamilzyla, #4127)
+
+* Fixed a bug with `sliderInput()` when used as a range slider that made it impossible to change the slider value when both handles were at the maximum value. (#4131)
+
+* `dateInput()` and `dateRangeInput()` no longer send immediate updates to the server when the user is typing a date input. Instead, it waits until the user presses Enter or clicks out of the field to send the update, avoiding spurious and incorrect date values. Note that an update is still sent immediately when the field is cleared. (#3664)
+
+* Fixed a bug in `onBookmark()` hook that caused elements to not be excluded from URL bookmarking. (#3762)
+
+* Fixed a bug with stack trace capturing that caused reactives with very long async promise chains (hundreds/thousands of steps) to become extremely slow. Chains this long are unlikely to be written by hand, but `{coro}` async generators and `{elmer}` async streaming were easily creating problematically long chains. (#4155)
+
+* Duplicate input and output IDs -- e.g. using `"debug"` for two inputs or two outputs -- or shared IDs -- e.g. using `"debug"` as the `inputId` for an input and an output -- now result in a console warning message, but not an error. When `devmode()` is enabled, an informative message is shown in the Shiny Client Console. We recommend all Shiny devs enable `devmode()` when developing Shiny apps locally. (#4101)
+
+* Updating the choices of a `selectizeInput()` via `updateSelectizeInput()` with `server = TRUE` no longer retains the selected choice as a deselected option if the current value is not part of the new choices. (@dvg-p4 #4142)
+
+* Fixed a bug where stack traces from `observeEvent()` were being stripped of stack frames too aggressively. (#4163)
+
+# shiny 1.9.1
+
+## Bug fixes
+
+* Fixed a bug introduced in v1.9.0 where the boundaries of hover/click/brush regions on plots were being incorrectly scaled when browser zoom was used. (#4111)
+
+# shiny 1.9.0
+
+## New busy indication feature
+
+Add the new `useBusyIndicators()` function to any UI definition to:
+  1. Add a spinner overlay on calculating/recalculating outputs.
+  2. Show a page-level pulsing banner when Shiny is busy calculating something (e.g., a download, side-effect, etc), but no calculating/recalculating outputs are visible.
+
+In a future version of Shiny, busy indication will be enabled by default, so we encourage you to try it out now, provide feedback, and report any issues.
+
+In addition, various properties of the spinners and pulse can be customized with `busyIndicatorOptions()`. For more details, see `?busyIndicatorOptions`. (#4040, #4104)
+
+## New features and improvements
+
+* The client-side TypeScript code for Shiny has been refactored so that the `Shiny` object is now an instance of class `ShinyClass`. (#4063)
+
+* In TypeScript, the `Shiny` object has a new property `initializedPromise`, which is a Promise-like object that can be `await`ed or chained with `.then()`. This Promise-like object corresponds to the `shiny:sessioninitialized` JavaScript event, but is easier to use because it can be used both before and after the events have occurred. (#4063)
+
 * Output bindings now include the `.recalculating` CSS class when they are first bound, up until the first render. This makes it possible/easier to show progress indication when the output is calculating for the first time. (#4039)
 
+* A new `shiny.client_devmode` option controls client-side devmode features, in particular the client-side error console introduced in shiny 1.8.1, independently of the R-side features of `shiny::devmode()`. This usage is primarily intended for automatic use in Shinylive. (#4073)
+
+* Added function `reactlogAddMark()` to programmatically add _mark_ed locations in the reactlog log without the requirement of keyboard bindings during an idle reactive moment. (#4103)
+
 ## Bug fixes
 
 * `downloadButton()` and `downloadLink()` are now disabled up until they are fully initialized. This prevents the user from clicking the button/link before the download is ready. (#4041)
+
 * Output bindings that are removed, invalidated, then inserted again (while invalidated) now correctly include the `.recalculating` CSS class. (#4039)
+
 * Fixed a recent issue with `uiOutput()` and `conditionalPanel()` not properly lower opacity when recalculation (in a Bootstrap 5 context). (#4027)
 
+* Image outputs that were scaled by CSS had certain regions that were unresponsive to hover/click/brush handlers. (#3234)
+
 # shiny 1.8.1.1
 
 * In v1.8.1, shiny.js starting throwing an error when input/output bindings have duplicate IDs. This error is now only thrown when `shiny::devmode(TRUE)` is enabled, so the issue is still made discoverable through the JS error console, but avoids unnecessarily breaking apps that happen to work with duplicate IDs.

 * Added a JavaScript error dialog, reporting errors that previously were only discoverable by opening the browser's devtools open. Since this dialog is mainly useful for debugging and development, it must be enabled with `shiny::devmode()`. (#3931)
 
-* `runExamples()` now uses the `{bslib}` package to generate a better looking result. It also gains a `package` argument so that other packages can leverage this same function to run Shiny app examples. For more, see `?runExamples`. (#3963, #4005)

 * Added `onUnhandledError()` to register a function that will be called when an unhandled error occurs in a Shiny app. Note that this handler doesn't stop the error or prevent the session from closing, but it can be used to log the error or to clean up session-specific resources.

-#' When busy indicators are enabled (see [useBusyIndicators()]), a spinner is

+#' @description
+#' Shiny automatically includes busy indicators, which more specifically means:
+#'   1. Calculating/recalculating outputs have a spinner overlay.
+#'   2. Outputs fade out/in when recalculating.
+#'   3. When no outputs are calculating/recalculating, but Shiny is busy

+#'     pulsing banner is shown.

+#' This function allows you to customize the appearance of these busy indicators
+#' by including the result of this function inside the app's UI. Note that,
+#' unless `spinner_selector` (or `fade_selector`) is specified, the spinner/fade
+#' customization applies to the parent element. If the customization should
+#' instead apply to the entire page, set `spinner_selector = 'html'` and

+# # Approach
+# Use flags on the reactive object to indicate whether to record OpenTelemetry spans.
+#
+# Cadence:
+# * `$.isRecordingOtel` - Whether to record OpenTelemetry spans for this reactive object
+# * `$.otelLabel` - The label to use for the OpenTelemetry span
+# * `$.otelAttrs` - Additional attributes to add to the OpenTelemetry span
+
+
+#' Add OpenTelemetry for reactivity to an object
+#'
+#' @description
+#'
+#' `enable_otel_*()` methods add OpenTelemetry flags for [reactive()] expressions
+#' and `render*` functions (like [renderText()], [renderTable()], ...).
+#'
+#' Wrapper to creating an active reactive OpenTelemetry span that closes when
+#' the reactive expression is done computing. Typically this is when the
+#' reactive expression finishes (synchronous) or when the returned promise is
+#' done computing (asynchronous).
+
+#' @section Async with OpenTelemetry:
+#'
+#'   With a reactive expression, the key and/or value expression can be
+#'   _asynchronous_. In other words, they can be promises --- not regular R
+#'   promises, but rather objects provided by the
+#'   \href{https://rstudio.github.io/promises/}{\pkg{promises}}  package, which
+#'   are similar to promises in JavaScript. (See [promises::promise()] for more
+#'   information.) You can also use [mirai::mirai()] or [future::future()]
+#'   objects to run code in a separate process or even on a remote machine.
+#'
+#'   When reactive expressions are being calculated in parallel (by having
+#'   another reactive promise compute in the main process), the currently active
+#'   OpenTelemetry span will be dynamically swapped out according to the
+#'   currently active reactive expression. This means that as long as a promise
+#'   was `then()`ed or `catch()`ed with an active OpenTelemetry span, the span
+#'   will be correctly propagated to the next step (and subsequently other
+#'   steps) in the promise chain.
+#'
+#'   While the common case is for a reactive expression to be created
+#'   synchronously, troubles arise when the reactive expression is created
+#'   asynchronously. The span **must** be created before the reactive expression
+#'   is executed, it **must** be active for the duration of the expression, and
+#'   it **must** not be closed until the reactive expression is done executing.
+#'   This is not easily achieved with a single function call, so we provide a
+#'   way to create a reactive expression that is bound to an OpenTelemetry
+#'   span.
+#'
+#' @section Span management and performance:
+#'
+#' Dev note - Barret 2025-10:
+#' Typically, an OpenTelemetry span (`otel_span`) will inherit from the parent
+#' span. This works well and we can think of the hierarchy as a tree. With
+#' `options("shiny.otel.collect" = <value>)`, we are able to control with a sliding
+#' dial how much of the tree we are interested in: "none", "session",
+#' "reactive_update", "reactivity", and finally "all".
+#'
+#' Leveraging this hierarchy, we can avoid creating spans that are not needed.
+#' The act of making a noop span takes on the order of 10microsec. Handling of
+#' the opspan is also in the 10s of microsecond range. We should avoid this when
+#' we **know** that we're not interested in the span.  Therefore, manually
+#' handling spans should be considered for Shiny.
+#'
+#' * Q:
+#'   * But what about app author who want the current span? Is there any
+#'     guarantee that the current span is expected `reactive()` span?
+#' * A:
+#'   * No. The current span is whatever the current span is. If the app author
+#'     wants a specific span, they should create it themselves.
+#' * Proof:
+#'   ```r
+#'   noop <- otel::get_active_span()
+#'   noop$get_context()$get_span_id()
+#'   #> [1] "0000000000000000"
+#'   ignore <- otelsdk::with_otel_record({
+#'     a <- otel::start_local_active_span("a")
+#'     a$get_context()$get_span_id() |> str()
+#'     otel::with_active_span(noop, {
+#'       otel::get_active_span()$get_context()$get_span_id() |> str()
+#'     })
+#'   })
+#'   #> chr "2645e95715841e75"
+#'   #> chr "2645e95715841e75"
+#'   # ## It is reasonable to expect the second id to be `0000000000000000`, but it's not.
+#'   ```
+#'   Therefore, the app author has no guarantee that the current span is the
+#'   span they're expecting. If the app author wants a specific span, they should
+#'   create it themselves and let natural inheritance take over.
+#'
+#' Given this, I will imagine that app authors will set
+#' `options("shiny.otel.collect" = "reactive_update")` as their default behavior.
+#' Enough to know things are happening, but not overwhelming from **everything**
+#' that is reactive.
+#'
+#' To _light up_ a specific area, users can call `withr::with_options(list("shiny.otel.collect" = "all"), { ... })`.
+#'
+#' @param x The object to add caching to.
+#' @param ... Future parameter expansion.

+#' Temporarily set OpenTelemetry (OTel) collection level
+#'
+#' @description
+#' Control Shiny's OTel collection level for particular reactive expression(s).
+#'
+#' `withOtelCollect()` sets the OpenTelemetry collection level for
+#' the duration of evaluating `expr`. `localOtelCollect()` sets the collection
+#' level for the remainder of the current function scope.
+#'
+#' @details
+#' Note that `"session"` and `"reactive_update"` levels are not permitted as
+#' these are runtime-specific levels that should only be set permanently via
+#' `options(shiny.otel.collect = ...)` or the `SHINY_OTEL_COLLECT` environment
+#' variable, not temporarily during reactive expression creation.
+#'
+#' @section Best practice:
+#'
+#' Best practice is to set the collection level for code that *creates* reactive
+#' expressions, not code that *runs* them. For instance:
+#'
+#' ```r
+#' # Disable telemetry for a reactive expression
+#' withOtelCollect("none", {
+#'   my_reactive <- reactive({ ... })
+#' })
+#'
+#' # Disable telemetry for a render function
+#' withOtelCollect("none", {
+#'   output$my_plot <- renderPlot({ ... })
+#' })
+#'
+#' #' # Disable telemetry for an observer
+#' withOtelCollect("none", {
+#'   observe({ ... }))
+#' })
+#'
+#' # Disable telemetry for an entire module
+#' withOtelCollect("none", {
+#'   my_result <- my_module("my_id")
+#' })
+#' # Use `my_result` as normal here
+#' ```
+#'
+#' NOTE: It's not recommended to pipe existing reactive objects into
+#' `withOtelCollect()` since they won't inherit their intended OTel settings,
+#' leading to confusion.
+#'
+#' @param collect Character string specifying the OpenTelemetry collection level.
+#'   Must be one of the following:
+#'
+#'     * `"none"` - No telemetry data collected
+#'     * `"reactivity"` - Collect reactive execution spans (includes session and
+#'       reactive update events)
+#'     * `"all"` - All available telemetry (currently equivalent to `"reactivity"`)
+#' @param expr Expression to evaluate with the specified collection level
+#'   (for `withOtelCollect()`).
+#' @param envir Environment where the collection level should be set
+#'   (for `localOtelCollect()`). Defaults to the parent frame.
+#'
+#' @return
+#' * `withOtelCollect()` returns the value of `expr`.
+#' * `localOtelCollect()` is called for its side effect and returns the previous
+#'   `collect` value invisibly.
+#'
