Installing 10.4.1 安装10.4.1

If you have already installed 10.4 Sydney (May 26th, 2020), installing 10.4 Sydney - Release 1 requires a full uninstall and reinstall. As part of the uninstall process, you will see an option for preserving your settings. This is enabled by default. Separately, you can also preserve settings with Settings Migration Tool.

如果您已经安装了10.4 Sydney (2020年5月26日) ，那么安装10.4 Sydney-Release 1需要完全卸载并重新安装。作为卸载过程的一部分，您将看到一个保存设置的选项。这是默认启用的。另外，还可以使用设置迁移工具保留设置。

Key Enhancements by product area in 10.4.1 10.4.1中按产品领域分列的主要改进

Supported Platforms 支持平台

RAD Studio now supports deploying apps on Windows Server 2019.

现在支持在 Windows Server 2019上部署应用程序。

IDE

Projects 项目

  • Package AUTO libsuffix: packages can now have an automatic version suffix, instead of manually updating and specifying the right version suffix with each new release. (The compiler quietly supported this in 10.4, but full support for the feature in the IDE and package project settings is introduced in 10.4.1.) 包 AUTO libsuffix: 包现在可以有一个自动的版本后缀，而不是手动更新和指定每个新版本的正确版本后缀。(编译器在10.4中悄悄地支持这个功能，但是在10.4.1中引入了对 IDE 和包项目设置中特性的完全支持。)
  • The Pentium-safe FDIV compiler option is no longer shown in the Delphi compiler options. 奔腾安全的 FDIV 编译器选项不再显示在 Delphi 编译器选项中
  • The Projects pane context menu items that were no longer available after 10.3 (invoked by right-clicking on an empty area in the Projects pane) are now available via a drop-down in the Projects pane toolbar. “项目”窗格上下文菜单项在10.3之后不再可用(通过右键单击“项目”窗格中的空白区域进行调用) ，现在可以通过“项目”工具栏下拉菜单项

Layouts 布局

  • Improved support for multi-monitor desktop layouts for those using multiple editor windows across multiple screens 改进了对跨多屏幕使用多个编辑器窗口的多显示器桌面布局的支持
  • The floating form designer has been removed. Note that you can still have multiple edit windows including a form designer in a second window, and in fact, support for that has been enhanced. 已删除浮动表单设计器。请注意，您仍然可以在第二个窗口中有多个编辑窗口，包括一个表单设计器，实际上，对该窗口的支持已经得到了增强
  • When the IDE switches layout, such as to/from debugging, or to/from startup (e.g. when opening or closing a project), if the same layout is specified for both states, the layout won’t be applied. This avoids unnecessarily switching layouts. 当 IDE 切换布局时，如从调试切换到/从调试切换到/从启动切换到/从启动切换到(如在打开或关闭项目时) ，如果为两种状态指定了相同的布局，则不会应用布局。这样可以避免不必要地切换布局
  • Desktop layouts which cannot be applied (i.e. are floating layouts, no longer supported, see above) will be listed in gray in the Desktop Layout combo box in the title bar. When a floating layout is applied, the IDE will instead show a dialog. 无法应用的桌面布局(即浮动布局，不再受支持，见上文)将在标题栏的“桌面布局”组合框中以灰色列出。当应用浮动布局时，IDE 将显示一个对话框
  • Improved support for 4K monitors: IDE now correctly restores layouts on a 4K monitor in situations where the 4K screen is not scaled 改进对4K 显示器的支持: IDE 现在可以在4K 显示器上正确地恢复布局，在4K 屏幕没有缩放的情况下
  • If the IDE expects a project’s .dsk file but it does not find it, it opens using the default layout. 如果 IDE 需要一个项目的.dsk 文件，但是没有找到它，它会使用默认布局打开

UI 用户界面

  • Options and other dialogs: 选项和其他对话框:
    • The Project Options, IDE Options, GetIt, and New Items dialogs now have scrollbar tracking (will move as you drag the scrollbar.) This includes scrolling with the mouse wheel 项目选项、 IDE 选项、 GetIt 和 New Items 对话框现在都有了滚动条跟踪(将在拖动滚动条时移动)这包括用鼠标滚轮滚动
    • The Options dialog (environment options) used to always open to show settings for the Win64 target platform; now it opens according to the currently active platform. “选项”对话框(环境选项)过去总是打开以显示 Win64目标平台的设置; 现在它根据当前活动平台打开
  • Several listview controls, which can be difficult to read in the dark theme, have been replaced by the virtual treeview. 一些在黑暗主题中难以阅读的 listview 控件已经被虚拟树视图所取代
  • The guided tour was removed from the Welcome page 欢迎页面上的导游已被删除
  • Several Object Inspector fixes, especially around flickering and selecting the wrong property 几个对象检视器修复，特别是在闪烁和选择错误的属性时
  • Improved the selection of items on the Structure pane, including where you would click on an item and another item was selected 改进了“结构”窗格中的项的选择，包括单击项和选择另一项的位置

General 

  • Broadcast to devices’ is off by default. This always accessed the network on IDE startup, causing errors for some customers. Now that it’s disabled, (valid) network errors will only occur if you turn it on. “向设备广播”默认是关闭的。这总是在 IDE 启动时访问网络，导致一些客户出错。现在它被禁用了，只有当您打开它时才会发生(有效的)网络错误
  • The names of the 64-bit Windows debuggers (visible in the Attach To Process dialog) have been clarified to explain which is for Delphi and which for C++. This should help you choose which debugger to use when attaching to a process. 64位 Windows 调试器的名称(在“附加到进程”对话框中可见)已经被澄清，以解释哪些是用于 Delphi，哪些是用于 c + + 。这应该有助于您选择在附加到进程时使用哪个调试器

  • The debug symbols search path now supports $(Platform) and $(Config) environment variables 调试符号搜索路径现在支持 $(Platform)和 $(Config)环境变量
  • The code editor used to let you select invalid encodings for a unit (applicable only to forms); these are now no longer available. 用于为单元选择无效编码的代码编辑器(仅适用于表单) ; 现在不再可用
  • An issue installing packages that presented as being unable to load a package, caused by packages with the filename case differing on disk and usually seen with large projects, has been resolved. 由于软件包的文件名在磁盘上不同，通常在大型项目中可以看到，所以安装软件包时出现了无法加载软件包的问题，这个问题已经得到解决

  • When code completion’s list was set to sort by name instead of scope, selecting an item inserted the wrong text. This is fixed. 当代码完成的列表被设置为按名称而不是范围排序时，选择一个插入错误文本的项。这是固定的
  • 10.4.1 also includes all fixes from 10.4 Patch 2, such as not inserting () braces when they already exist, pressing Space not selecting the current completion, completion lagging, and then not entering text correctly, Error Insight in the Structure pane lagging by a keystroke, and so forth. 10.4.1还包括来自10.4补丁2的所有修复，例如当已经存在时不插入()括号，按空格键不选择当前完成，完成滞后，然后不正确输入文本，结构窗格中的错误洞察滞后于按键，等等

There are some improvements in package references and C++ HPP files generation. The release also improves compiler performance in a few areas, optimizing unit names lookup and other internal searches, benefiting large projects. There are also a few code generation improvements (that is, cases in which the compiler can generate code that performs better).

10.4.1版本在几个方面改进了 Delphi 编译器。特别是重点是支持 LSP 代码完成，以及提高托管记录的质量，但我们也处理了一些10.4回归和意外的变更(包括 goto 语句和其他不常见场景的问题)。在包引用和 c + + HPP 文件生成方面有一些改进。该版本还提高了编译器在一些领域的性能，优化了单元名称查找和其他内部搜索，使大型项目受益。还有一些代码生成方面的改进(也就是说，编译器可以生成性能更好的代码)。
