Dear Android Studio Developer,

As an app developer on Google Play, we wanted to make you aware of an important security update for Android Studio.

On May 11th, we released the Android Studio 2.1.1 update. This incremental update addresses a security vulnerability in the underlying IntelliJ platform that affects all previous versions of Android Studio. The vulnerability concerns the IDE itself and has no effect on individual apps.

Please update to Android Studio 2.1.1 as soon as possible. More information about the vulnerability can be found in this G+ posting. JetBrains has also released more details on the vulnerability.

To address this security vulnerability, simply go into Android Studio and check updates. For OS X users, navigate to the Android Studio Menu and click Check for Updates. For Windows or Linux users, navigate to the Help menu and click Check for Updates. You should be running at least Android Studio 2.1.1. The update message was sent as a in-product notification to all users of Android Studio. If you want a new install, you can download v2.1.1 from the Android Studio website.

If you’re still using v1.5.x and not able to switch to v2.x immediately, please download Android Studio v1.5.2 from the Android Studio tools website.

Regards,

The Android Studio Team

バージョン 2.1.1 にしておけばいいということですかね.

いまやメールもすぐには信じられなくなってるのは私だけでしょうか.

きもくないすか?

ButterKnife 8.0 に更新で @Bind → @BindView など

更新されています.

Butter_Knife

Version 8.0.0 (2016-04-25)

- @Bind becomes @BindView and @BindViews (one view and multiple views, respectively).
- Calls to bind now return an Unbinder instance which can be used to null references. - This replaces the unbind API and adds support for being able to clear listeners.
- New: @BindArray binds String, CharSequence, and int arrays and TypeArray to fields.
- New: @BindBitmap binds Bitmap instances from resources to fields.
- @BindDrawable now supports a tint field which accepts a theme attribute.

-The runtime and compiler are now split into two artifacts.

compile 'com.jakewharton:butterknife:8.0.0'
apt 'com.jakewharton:butterknife-compiler:8.0.0'

- New: apply overloads which accept a single view and arrays of views.
- ProGuard rules now ship inside of the library and are included automatically.
- @Optional annotation is back to mark methods as being optional.

明示することで, バインドできるリソース範囲を広げながら処理速度は落とさない.

あと, proguard 記述は不要なのだとさ.
