+## [0.17.0] - Unreleased
+
+### Added
+
+- Added `Document::child_count(row_index)` to JSON and YAML for querying immediate container sizes independently of folding; empty containers return `Some(0)`, closing rows return their opening container's count, and non-container rows return `None`
+- Added optional child-count annotations for collapsed and empty JSON and YAML containers, such as `[…] (3 items)` and `{…} (2 keys)`, controlled by `show_child_count` and `child_count_style`
+
+### Changed
+
+- Added `child_count` to `ContainerNode::Open`; direct constructors and exhaustive patterns must account for the new field
+- Extended JSON and YAML `Config` with child-count settings, disabled by default; existing serialized configurations retain the previous display, and pretty-printed exports omit annotations
+- Updated `promkit-widgets` to `v0.10.0`
+
+## [0.16.0] - 2026-09-07
+
+### Added
+
+- Added `Document::row_index_for_path` and `Document::move_to_path` to JSON and YAML for navigating jq-style paths, including object keys, array indices, quoted string keys, and YAML non-string scalar keys
+- Added zero-based document indexes to path navigation for JSON Lines and YAML document streams; moving to a path expands folded ancestors while preserving unrelated folding state
+- Added `Document::selected_path()` to retrieve the selected row's document index and jq-style path
+
+### Changed
+
+- Improved selected-path lookup with compact per-row parent and array-index metadata
+- Updated workspace dependencies, `promkit-core` to `v0.6.1`, and `promkit-widgets` to `v0.9.0`
+
+## [0.15.0] - 2026-08-16
+
+### Added
+
+- Added `WidgetLayout::height_policy` with `HeightPolicy::OrderedContent`, `FairContent`, and `FairFill` for content-based allocation, equal-share limits, and padded fill areas
+- Added configurable text overflow through `text::config::OverflowMode`, supporting wrapping by default or truncation with an ellipsis
+- Added terminal regression scenarios for renderer height allocation
+
+### Changed
+
+- Replaced the mutating `PrefixSearch::search` API with `PrefixSearch::query`, which returns an independently selectable `PrefixSearchResult` snapshot
+- Changed prefix-search widget state from `State::prefix_search` to `State::result`, moving candidate selection and navigation to the result snapshot
+- Extracted renderer height allocation into a dedicated module; fair-content panes stay within their equal share without redistributing unused rows
+- Updated `promkit-core` to `v0.6.0` and `promkit-widgets` to `v0.8.0`
+
+### Removed
+
+- Removed the status widget and its `status` Cargo feature from `promkit` and `promkit-widgets`

+## JSON and YAML child counts
+
+JSON and YAML documents retain the number of immediate array/sequence elements
+or object/mapping entries, independently of folding. Query a container with
+`Document::child_count(row_index)`, using a zero-based index into `Document::rows()`.
+Empty containers return `Some(0)`; closing rows return the opening container's
+count. Scalars, YAML document separators, and invalid indices return `None`.
+
+Enable annotations through the widget configuration:
+
+```rust
+use promkit_widgets::json::{Config, Document, State};
+
+let mut state = State {
+    document: Document::from_str(r#"{"items": [1, 2, 3]}"#)?,
+    config: Config {
+        show_child_count: true,
+        ..Default::default()
+    },
+};
+assert_eq!(state.document.child_count(1), Some(3));
+state.document.toggle_at(1);
+// The items row now displays: "items": […] (3 items)
+```
+
+The same APIs are available under `promkit_widgets::yaml`. Annotations appear
+beside collapsed or empty containers, for example `{…} (2 keys)` and `[] (0 items)`.
+`show_child_count` defaults to `false`; `child_count_style` controls annotation
+styling. Changing these settings does not fold or expand containers. Existing
+`toggle()` / `toggle_at()` operations control folding. Pretty-printed data exports
+do not include annotations.
+
+When constructing `ContainerNode::Open` directly, supply its new `child_count`
+field. Existing exhaustive `Open` patterns must include the field or `..`.
+For `Config` struct literals, use `..Default::default()` or supply the new fields;
+stored Serde configurations without these fields keep the default display.
