德尔福语言特性列表及其引入/不推荐的版本 [英] List of Delphi language features and version in which they were introduced/deprecated

问题描述

在我开始之前，我想指出，我已经通过Google诚恳地，真诚地搜索了这样一个事情，并找不到一个。

我需要（对于我正在开发的项目）所有Delphi的列表（2007年到最新发布的版本，我不再支持2007年以前的任何版本）语言特性，以及它们被引入的版本（如适用）已被弃用，改进或删除。

之前我已经注意到有关Stack Overflow的类似问题，尽管其中大部分都是以哪个功能是最好的，并被视为不合适。

如果有人知道这样的列表（或有足够的空闲时间编译一个），我将非常感谢。

接受的答案将包含一个链接到这样的列表或列表本身。

  Before I begin, I would like to point out that I have honestly and genuinely searched repeatedly and exhaustively via Google for such a thing, and been unable to find one.

  I require (for a project I'm developing) a list of all Delphi (2007 to the very latest released version, I no longer support any version older than 2007) "Language Features", and the versions in which they were introduced and (where applicable) deprecated, improved or removed.

  I have noted similar questions to this on Stack Overflow before, though most of those were phrased in the form of "which feature is best", and closed as deemed unsuitable.

  If anyone knows of such a list (or has enough spare time to compile one), I would be very grateful.

  The accepted answer will either contain a link to such a list, or the list itself.
