Edge 80

Hello.

Microsft Edge 80 was released for Windows and MacOS in last weekend.

Edge on my mac was updated automatically by Microsoft AutoUpdate that check updates of not only Edge but also other MS apps. like MS word, excel, power point and so on.

I'm looking for a page that explain what's new on Edge 80. I expected that each release that count up major version number publishes corresponding release note. But I've not found that yet. Are the changes as same as Chrome 80?

I will keep conitnue to research how MS Edge is.

Microsoft Edge 79

Hello.

The new version of Microsoft Edge was released on Jan. 15. This is built on the Chromium engine and the released vesion is 79.0.

We should install new Edge by our hands instead of Microsoft update now. But I heard that current Edge will be updated to new one by Windows update in several manths.

How to get

New Edge is available on not only Windows 10, but also MacOS, android and iOS.

We can get new Edge installer from the web site below for Windows 10 and Mac users. New Edge has new icon. For android users or iPhone users, Google Play and Apple Store provide that.
https://www.microsoft.com/en-us/edge

Further information about upgrading Edge is here.
https://blogs.windows.com/msedgedev/2020/01/15/upgrading-new-microsoft-edge-79-chromium/

I understood that Edge 79 was provided for users to prepare to switch to new Edge before that will be provided by Windows update. After upgrading, new Edge will be automatically updated on aroud 6 week cycle, that will be like Chrome or Firefox.

References

We can download the installer and get support information here.

For people who want to know further or newer information, "Microsoft Edge Insider" will be fit them.

The latest information will be available at "community" page.

3) https://blogs.windows.com/msedgedev/2019/07/16/microsoft-edge-enterprise-evaluation-roadmap/

What will be changed.

New Edge will be upgraded on around 6 week cycle like Chrome or Firefox and this update is independent of Windows update. There are 4 update channels. The stable with 6 week cycle, the beta with 6 week cycle but newer version than stable, the DEV with every week and the CAN(Cannary) with every night. 1), 2)

Thanks to Choromium engine, new Edge can render web pages as same as Chome and boost the imprementation of HTML5 features and supporting developments of browser extentions. Firefox and Chrome have released new features (e.g. blocking user tracking by website, improving user password protection, imprimenting HTML5 features and so on) in short cycle. Additionaly, the user community have developed a lot of extensions with published browser API and documents. In the other hand, Edge looked steady even though Windows keeps IE11.

New Edge is considered to be used in enterprize. Acording to the article 3), administrators can controll updating of Edge. In addition, new Edge has (will have ?) IE 11 conpatible mode.

User Agent

I captured the HTTP_USER_AGENT of new Edge by every OS. Windows or MacOS versions are identified by "Edg/", Android version "EdgA/" and iOS or iPadOS versions "EdgiOS/".

We found nothing of problem to use WebClass with it.

Firefox 72

Hello.

Firefox Desktop Browser 72 was released last week.

Firefox release schedules

The release note for developers lists news and changes on APIs or developer tools that may be used by web contents developers or firefox plugin developes.

You can get overview of the new release changes and prepare to manage influence on WebClass functions or your learning materials.

Pickup for webclass

I think there is nothing special to do for using WebClass with new firefox.

The design to identify easily

Do you have difficulty to recognize buttons and notes on WebClass? If you have challanging to recognize or distinguish colors, how do you look at pages on WebClass? We have been trying to make the UI "easy to use for everyone", we think. But we haven't considered the accessibility from another person's view. So, we are going to improve that. This articles sumerize the references about the accessibility guideline and check tools in Japan.

"Public Site Operation Guidelines(みんなの公共サイト運用ガイドライン)" from Ministry of Internal Affairs and Communications

We can learn a lot about accessibility guideline at this page.

http://www.soumu.go.jp/main_sosiki/joho_tsusin/b_free/guideline.html

This is a guidance for the gavernment and public instutusions in Japan to make their websites barrier-free. For specific guidelines, refer to “JIS X 8341-3: 2016”, but the contents are almost the same as WCAG 2.0 (described later). There are survey reports and seminar guidance for national and local public organizations, too.

I was interested in the last one, “Introduction video on how to use web pages for people with disabilities (障害者のウェブページ利用方法の紹介ビデオ)”. Although it is very important to design UI with solid understanding about users, we tend to think all people as same as us. It's hard to imagene how visual or color challenging people use computer. I had never used the accessibility support tool that is installed on modern OSs. Theses videos help us to know that.

Web Content Accessibility Guideline

The website “Web Accessibility Infrastructure Committee” (https://waic.jp) provides the information on “JIS X 8341-3: 2016”. This page is linked from the guidance page on Ministry of Internal Affairs and Communications we read at last section. This committee held a seminar on October 17th.

In addition to JIS X 8341-3: 2016, the translation into Japanese of the original WCAG 2.0 is also posted here.

-Quick reference
  -https://waic.jp/docs/WCAG20/quickref/
-Explanation of each quick reference item
  -https://waic.jp/docs/UNDERSTANDING-WCAG20/Overview.html
-Examples of implementation and verification methods
  -https://waic.jp/docs/WCAG-TECHS/Overview.html#abstract

Looking at the quick reference, there are some aspects to treat accessibility, and each level and detailed explanation are associated. For example, looking at “1.4.3 Contrast (minimum) level AA”, a concrete reference value is also shown: “The visual presentation of text and text images has a contrast ratio of at least 4.5: 1.”

I think that having specific viewpoints and standards is important for implementation and inspection.

Color universal design

Regarding color, the NPO Color Universal Design Organization (https://www2.cudo.jp/wp/) has released the “Color Universal Design Recommended Color Set” (http://www2.cudo.jp/wp/?page_id=1565)

This is a color palette that combines color combinations that are easy to distinguish even to those who are difficult to distinguish colors. The color palette supports three patterns for painting, printing, and screen, and a guidebook for use is also available in PDF.

According to the FAQ of the guidebook, the colors that are difficult to distinguish, or the colors that appear to be the same color, are different by each person who is difficult to identify colors. Therefore, this color palette is not a perfect pattern, but it is a color that is relatively easy to distinguish for as many people as possible.

Regardless of whether or not to use this color palette, I thought that knowing a little about how the color palette was created would be helpful in our future inspections.

Check tool

How can I make sure that I met the WCAG 2.0 sentence:"Visual presentation of text and text images has a contrast ratio of at least 4.5: 1"? Regarding the contrast ratio, You can check that on this web page based on the WCAG 2.0 criteria.

https://lab.syncer.jp/Tool/Color-Contrast-Checker/

Also, The Ministry of Internal Affairs and Communications provides checker tool called "Minna Accessibility Assessment Tool: miChecker".

http://www.soumu.go.jp/main_sosiki/joho_tsusin/b_free/michecker.html

Firefox also has an accessibility check tool in a developer tool panel. Open the developer tools, open the "Accessibility" tab and enable it. I tried to check the contrast on the Datapacific homepage, but NG appeared.

Firefox accessibility check

In addition, Chrome has a browser extension that lets you recreate the web page view of people with low vision or color distinguishing hardlyness.

from now on

Actually, we cannot meet with WCAG2.0 at once. We should picking up the minimum items to be met. Next, I would like to establish know-how for checking and imprementing that. Then, we might be able to keep improving accessibility along with WCAG2.0.
