Microsoftは11月2日(現地時間)、Edgeブラウザの最新安定版「Microsoft Edge 119」をリリースしました。
Microsoft Edgeの最新版は自動更新機能によってインストールされますが、ブラウザのヘルプページ「edge://settings/help」を開き、手動でインストールすることもできます。
Edge 119では、通信を圧縮してパフォーマンスを改善する圧縮辞書トランスポートのオリジントライアルによるサポートが行われています。また、beforeunloadイベントの動作の変更や、分割タブの復元機能の改良(セッションの復元にも対応)、サイドバーアプリの管理機能の追加も行われています。
リリースノートは以下の通りです:
Feature updates
Compression Dictionary Transport support. A version of the Compression Dictionary Transport feature is available for sites to use by participating in the associated origin trial. If your network uses a middlebox that inspects network traffic and/or you previously encountered issues with the ZSDCH feature, review the Considerations for zstd-based Shared Dictionary Compression for HTTP page which contains updated guidance.
Behavioral changes to the beforeunload event. The behavior of the beforeunload event has changed such that calling preventDefault in a beforeunload event handler triggers a confirmation dialog. Setting returnValue to an empty string in a beforeunload event handler no longer triggers a confirmation dialog. This behavior takes effect starting in Microsoft Edge version 119. Administrators can temporarily opt out of this functionality by disabling the BeforeunloadEventCancelByPreventDefaultEnabled policy.
Split screen restore improvements. Split screen allows you to simultaneously work on multiple tasks across two, side-by-side screens in one browsing tab to boost your productivity and multitask more efficiently. Now after the browser is restarted and the previous session is restored, the split tab will also be restored.
Additional capability to manage sidebar apps. Administrators can utilize the "sidebar_auto_open_blocked" ExtensionSettings policy field to control the auto-open behavior of sidebar apps. For more information, see Detailed guide to the ExtensionSettings policy.
Updates to Microsoft Edge enterprise sync settings page. When the ForceSyncTypes and SyncTypesListDisabled polices are used concurrently, the sync settings page (
edge://settings/profiles/sync) accurately show the status for each data type.
- SwitchIntranetSitesToWorkProfile - Switch intranet sites to a work profile
- SwitchSitesOnIEModeSiteListToWorkProfile - Switch sites on the IE mode site list to a work profile
- OrganizationalBrandingOnWorkProfileUIEnabled - Allow the use of your organization's branding assets from M365 on the profile-related UI of a work profile
