== Upgrading from a previous release ==

Upgrading is not recommended because of various bugs. One of those bugs is Bug:1284635. But, if you still prefer to perform an upgrade, follow these instructions:

To upgrade from Ubuntu Studio 13.10 using GUI tools:
 * Open Software Sources.
 * Press Alt+F2 and type in "update-manager" (without the quotes) into the command box.
 * Update Manager should open up and tell you: New distribution release '14.04 LTS' is available.
 * Click Upgrade and follow the on-screen instructions.  

To upgrade from Ubuntu Studio 13.10 using CLI tools:
 * Install the {{{update-manager-core

package if it is not already installed.

}}}

== 前回のリリースからのアップグレード

様々なバグのため、アップグレードは推奨されません。そういったバグの一つがBug:1284635です。しかし、それでもまたアップグレードを望むのであれば、以下の案内に従います:

= Feature Changes for 14.04 LTS =

 * New installer ubiquity plugin which allows you to select packages to install from our workflow metas, audio, video, graphics, photography and publishing.
 * linux-lowlatency is now merged with linux-generic master branch, which means the two are almost identical feature wise. linux-lowlatency continues to be configured for preemtiveness and irq threading and depends on the rtirq script.
 * gtk3 indicator support in the panel
 * IBus was dropped (Bug:1284635)
 * Speech-dispatcher and espeak were added, in addition to Orca and brltty, to further improve accessibility with braille and speech support during installation.

14.04 LTSの機能変更

== Updated Packages ==

As with every new release, packages--applications and software of all kinds--are being updated at a rapid pace. Many of these packages came from an automatic sync from [[http://www.debian.org|Debian]]'s unstable branch; others have been explicitly pulled in for Ubuntu 14.04 LTS.

For a list of all packages being accepted for Ubuntu 14.04 LTS, please subscribe to [[https://lists.ubuntu.com/mailman/listinfo/trusty-changes|trusty-changes]].

アップデートされたパッケージ

全ての新リリース同様、全種類のアプリケーションとソフトウェアのパッケージが速いペースでアップデートされます。パッケージの多くは Debian の不安定版ブランチ由来で、残りはUbuntu 14.04 LTSのために用意されました。 

== Known issues ==
 * Wrong default kb layout in login screen after installation.
 * Wrong default language in session after installation (Bug:1308936)
 * usb2/usb3 audio devices may perform badly (Bug:1308628)
 * Xfce4 Power Manager does not restore screen power (Bug:1259339). You can try running {{{xrandr'

, which has worked as a problem-free workaround for some users. Alternatively, to restore a working desktop go to TTY1 (Ctrl+Alt+F1) and restart lightdm with sudo service lightdm restart. NOTE: You will lose all unsaved work in progress! It appears that all instances of this bug so far are caused by suspending by closing the laptop lid - suspending from the logout dialog works to the best of our knowledge.

To see a list of known bugs in the common infrastructure, refer to the Ubuntu release notes. }}}
