◆ From the next release, the version number will be 3 digits
With the next Chrome update scheduled for March 29th, the version number will finally be a 3-digit '100' . Some server code presume that the browser version number is two digits, so use the ' # force-major-version-to-100 ' flag in advance. It is recommended to check if the site works properly.
To test, just access 'chrome: // flags / # force-major-version-to-100' and set the setting to 'Enabled'.

◆ Supports ' cascade layer ' that can set CSS priority for each layer

'Cascade layer' supported from Chrome 99 determines the layer name and priority at the beginning of the file, and describes each style in the layer to resolve conflicts according to the layer priority. It is a mechanism.
◆ It is possible to display the date selection UI from JavaScript
In Chrome, if the page has a date type input field, a 'date picker' will be displayed where you can easily enter the date by clicking the calendar mark to the right of the input field. From Chrome 99, it is possible to call and display the UI of the input field from JavaScript, including the date picker.
