新版变化
Chrome v99.0.4844.51 正式版（2022-02-15）
谷歌浏览器v99正式版主要更新，优化了JavaScript（JS）adoptedStyleSheets规范的实现，这之前使用的是FrozenArray支持阵列，但现在将利用ObservableArray，新的方法将使突变JS数组变得更加容易，自2018年以来，微软、Mozilla、苹果和Google之间一直在争论这一规范的变化。新版本还整合了一个新的手写识别API，网络开发者可以利用它来提供墨迹功能，例如在笔记类网络应用中，他们将不需要依靠第三方的整合。谈到网络应用，Chrome 99将允许已安装的渐进式网络应用程序（PWA）在屏幕上覆盖更多区域，以便它们看起来更像本地应用而不是网络应用。
谷歌浏览器v98正式版主要更新，增加了对COLRv1彩色渐变矢量字体的支持，这是其COLRv0的进化版。它们以渐变、合成、变换、多色字母的形式带来了更具表现力的视觉能力，甚至在非常小的字体尺寸下也是如此。Google对此介绍说，它能够使用COLRv1字体格式渲染诺托彩色表情符号，经过WOFF2压缩后的大小为1.85MB。同时，对于同样的表情符号，标准的位图字体占用了9MB，在节省系统资源开销上，这是个重大的改进。
The official version of Google Chrome has ushered in the release of the first version of v99. The detailed version number is v99.0.4844.51. The last official version, v98.0.4758.102, was released on February 15. After 15 days, Google released a new version. Chrome browser, this upgrade is mainly to update the security fixes and stability improvements and user experience.
New version changes
Chrome v99.0.4844.51 official version (2022-02-15)
The main update of the official version of Google Chrome v99 has optimized the implementation of the JavaScript (JS) adoptedStyleSheets specification, which previously used FrozenArray to support arrays, but will now utilize ObservableArray, the new method will make it easier to mutate JS arrays, since 2018 This norm change has been debated for years between Microsoft, Mozilla, Apple and Google. The new version also integrates a new handwriting recognition API, which web developers can use to provide inking capabilities, such as note-taking web applications, they will not need to rely on third-party integration. Speaking of web apps, Chrome 99 will allow installed Progressive Web Apps (PWAs) to cover more area on the screen so that they look more like native apps than web apps.
The main update of the official version of Google Chrome v98 adds support for COLRv1 color gradient vector fonts, which is an evolutionary version of its COLRv0. They bring more expressive visual power in the form of gradients, composites, transformations, multicolor letters, even at very small font sizes. According to Google, it can render the Noto color emoji using the COLRv1 font format, which is 1.85MB in size after WOFF2 compression. At the same time, for the same emoji, the standard bitmap font takes up 9MB, which is a significant improvement in saving system resource overhead.
The main update of the official version of Google Chrome v97, the introduction of the WebTransport API, WebTransport is a protocol framework similar to the WebRTC data channel, but mainly used for clients limited by the network security model, using secure, multiplex transmission and remote servers. communication. WebTransport uses the HTTP/3 protocol for bidirectional transport. Unlike TCP-based WebSockets, WebTransport relies on UDP-like packets and cancelable streams. WebTransport is currently in Working Draft status at the W3C. Chrome 97 also adds CSS media queries for HDR display detection, new JavaScript methods, more native web app support, and more.
The main update of the official version of Google Chrome v96 allows users to enable a Windows 11-style right-click menu on the user interface by enabling the specified experiment flag in the Experiments page. More specifically, Google added a new Windows 11-style menu flag that allows the browser to "use Windows 11-style menus wherever possible," so it's consistent with the rest of the system's interface. This flag is still disabled by default, most likely because Google has been working hard to perfect it, so expect additional news on this in an upcoming update. Others also add some minor developer features, some user improvements such as backward caching on the desktop, and bug fixes and security maintenance work.
谷歌浏览器v97正式版主要更新，引入了WebTransport API，WebTransport是一个类似于WebRTC数据通道的协议框架，但主要是用于受网络安全模型限制的客户端，使用安全、多复式传输与远程服务器进行通信。WebTransport使用HTTP/3协议进行双向传输。与基于TCP的WebSockets不同，WebTransport依赖于类似UDP的数据包和可取消的流。WebTransport目前处于W3C的工作草案状态。Chrome 97还增加了用于HDR显示检测的 CSS媒体查询、新的JavaScript方法、更多的本地网络应用支持等。
谷歌浏览器v96正式版主要更新，允许用户在Experiments页面中通过启用指定实验flag，可以在用户界面上启用Windows 11风格的右键菜单。更具体地说，Google增加了一个新的Windows 11风格菜单标志，允许浏览器“尽可能使用Windows 11风格的菜单”，因此与系统的其他界面保持一致。默认情况下，这个标志仍然是禁用的，很可能是因为Google一直在努力完善它，所以预计在即将到来的更新中会有这方面的额外消息。其他还增加了一些次要的开发者功能，一些用户改进，如桌面上的后向缓存，以及问题修复和安全维护工作。
