About these release notes. Phew, what a release! Since the last release 4 years ago, we have merged 1700+ patches with 9000+ method changes. Beyond documenting technical changes in detail, these notes highlight the bigger picture and the overall impact of major developments. Along the way, you will find plenty of links to code pointers and interactive examples. Thus, these release notes serve not only as a changelog but also as a hands-on guide to exploring new features and mechanisms in Squeak. 关于这些版本说明。呼，真是个大版本！自 4 年前的上一个版本发布以来，我们合并了 1700 多个补丁，涉及 9000 多处方法更改。除了详细记录技术变更外，这些说明还强调了宏观背景和重大开发带来的整体影响。在此过程中，您会发现大量指向代码指针和交互式示例的链接。因此，这些版本说明不仅是变更日志，也是探索 Squeak 中新功能和机制的实践指南。

Morphic (up to Morphic-ct.2218/MorphicTests-ct.97) Morphic (更新至 Morphic-ct.2218/MorphicTests-ct.97)

Major overhaul of tree morphs: Improves colors and mouse and keyboard shortcuts for navigating trees. Revises type-to-filter similar to lists, highlights search terms, and enables searching single columns via [TAB]. Adds a configurable filter mode to search within the current selection, all visible nodes, or the entire tree. Introduces a recursive “find”/“find again” feature available via [CMD] + [F]/[CMD] + [G]. Adds a flag for automatic expansion of trees. Improves support for drag’n’drop by automatically expanding nodes during dragging after one second of hovering. Miscellaneous improvements for layouting, rendering, and event handling in trees.
树状 Morph 的重大重构：改进了用于导航树的颜色以及鼠标和键盘快捷键。修改了类似于列表的“输入即过滤”功能，高亮显示搜索词，并支持通过 [TAB] 键搜索单列。增加了可配置的过滤模式，以在当前选择、所有可见节点或整个树中进行搜索。引入了可通过 [CMD] + [F]/[CMD] + [G] 使用的递归“查找”/“再次查找”功能。增加了树自动展开的标志。改进了拖放支持，在拖动过程中悬停一秒后自动展开节点。对树的布局、渲染和事件处理进行了各种改进。
In the world, supports dropping of class references, system and method categories, and inspector and explorer fields to display them in a new window/widget.
在工作区（World）中，支持拖放类引用、系统和方法类别，以及检查器和资源管理器字段，以便在新的窗口/小部件中显示它们。
For mouse interactions, adds new preferences to customize the double-click time and drag thresholds.
对于鼠标交互，增加了自定义双击时间和拖动阈值的新首选项。
In the docking bar window menu, adds an item to collapse windows. Makes “find workspace” easier to use by expanding the selected window if collapsed. Reorders and decorates items in the help menu.
在停靠栏窗口菜单中，添加了折叠窗口的选项。通过在折叠时展开选定窗口，使“查找工作区”更易于使用。重新排序并装饰了帮助菜单中的项目。
Text editors: Underlines links (like this one!) during hovering and makes clicking and text selection through them more convenient. When enclosing/unenclosing a selection in single/double quotes, nested quotes are now automatically escaped/unescaped.
文本编辑器：在悬停时为链接（比如这个！）添加下划线，并使点击和通过链接进行文本选择更加方便。在用单/双引号括起或取消括起选定内容时，嵌套引号现在会自动转义/反转义。
Morphic API: Allows morphs to opt out of individual halo events and to specify a balloon text via a block instead of a selector.
Morphic API：允许 Morph 选择退出个别光环（halo）事件，并允许通过代码块（block）而不是选择器（selector）来指定气泡提示文本。
Menu construction: Adds new utilities for adding item groups and temporarily switching action targets during construction. #addList: now interprets backslashes in help tuples as line breaks. Automatically trims trailing lines between menu items.
菜单构建：增加了用于添加项目组和在构建期间临时切换操作目标的新工具。#addList: 现在将帮助元组中的反斜杠解释为换行符。自动修剪菜单项之间的尾随空行。
Revises the debug menus of several morphs by adding a time-profiler shortcut for buttons, providing access to the list and tree contents, and making existing “browse action” and “debug action” commands faster and more reliable.
修改了多个 Morph 的调试菜单，为按钮添加了时间分析器快捷方式，提供了对列表和树内容的访问，并使现有的“浏览操作”和“调试操作”命令更快、更可靠。
Honors the preference “Open Tools Attached to Mouse Cursor” in Morph>>openAsTool.
在 Morph>>openAsTool 中遵循“打开工具时跟随鼠标光标”的首选项。
Lots of UI tweaks and stability improvements: Improves theme support for progress bars, text morph menus, and dialog windows. Improves high-DPI support for buttons, scroll panes, sliders, menus, multi-selection lists, trees, drop-shadows, the scratch pad, the keyboard exerciser, and others. Improves multilingual support in different places.
大量的 UI 调整和稳定性改进：改进了对进度条、文本 Morph 菜单和对话框窗口的主题支持。改进了对按钮、滚动窗格、滑块、菜单、多选列表、树、投影、便笺簿、键盘练习器等的高 DPI 支持。在不同位置改进了多语言支持。
