Update CHANGELOG.md

In rare cases, it seems either that `onDraw` is called before `onMeasure` or
that `onMeasure` is called with a view that has zero height/width. This causes
`reallocateCache` to produce an IllegalArgumentException. This patch ensures
that diameter is never zero.

Fixes #904

-## Features
-
-<b>Simple, beautiful and modern interface</b>
-Loop has a minimalistic interface that is easy to use and follows the material design guidelines.
-
-<b>Habit score</b>
-In addition to showing your current streak, Loop has an advanced algorithm for calculating the strength of your habits. Every repetition makes your habit stronger, and every missed day makes it weaker. A few missed days after a long streak, however, will not completely destroy your entire progress.
-
-<b>Detailed graphs and statistics</b>
-Clearly see how your habits improved over time with beautiful and detailed graphs. Scroll back to see the complete history of your habits.
-
-<b>Flexible schedules</b>
-Supports both daily habits and habits with more complex schedules, such as 3 times every week; one time every other week; or every other day.
-
-<b>Reminders</b>
-Create an individual reminder for each habit, at a chosen hour of the day. Easily check, dismiss or snooze your habit directly from the notification, without opening the app.
-
-<b>Optimized for smartwatches</b>
-Reminders can be checked, snoozed or dismissed directly from your Android Wear watch.
-
-<b>Completely ad-free and open source</b>
-There are absolutely no advertisements, annoying notifications or intrusive permissions in this app, and there will never be. The complete source code is available under the GPLv3.

+## Features
+
+* <b>Beautiful, minimalistic and lightweight interface.</b>
+Loop has an elegant and minimalistic interface that is very easy to use, even for first-time users. Highly optimized for speed, the app works well even on older phones.
+
+* <b>Habit score.</b>
+Loop has an advanced formula for calculating the strength of your habits. Every repetition makes your habit stronger and every missed day makes it weaker. A few missed days after a long streak, however, will not completely destroy your progress, unlike many other don't-break-the-chain apps.
+
+* <b>Flexible schedules.</b>
+In addition to daily habits, Loop supports habits with more complex schedules, such as 3 times per week or every other day.
+
+* <b>Reminders.</b>
+Schedule notifications to remind you of your habits. Each habit can have its own reminder, at a chosen time of the day. Easily check or dismiss your habit directly from the notification.
+
+* <b>Widgets.</b>
+Be reminded of your habits whenever you unlock your phone. Colorful widgets allow you to track your habits directly from your home screen, without even opening the app.
+
+* <b>Take control of your data.</b>
+If you want to further analyze your data, or move it to another service, Loop allows you to export it to spreadsheets (CSV) or to a database file (SQLite). For power users, checkmarks can be added through other apps, such as Tasker.
+
+* <b>No limitations.</b>
+Track as many habits as you wish. Loop imposes no artificial limits on how many habits you can have. All features are available to all users. There are no in-app purchases.
+
+* <b>Completely ad-free and open source.</b>
+There are no advertisements, annoying notifications or intrusive permissions in this app, and there will never be. The app is completely open-source (GPLv3).
+
+* <b>Works offline and respects your privacy.</b>
+Loop doesn't require an Internet connection or online account registration. Your confidential data is never sent to anyone. Neither the developers nor any third-parties have access to it.
+
+## Installing
+
+The easiest way to install Loop is through the [Google Play Store][playstore] or [F-Droid][fdroid].
+You may also download and install the APK from the [releases page][releases];
+note, however, that the app will not be updated automatically.  To build this
+app from the source code, see [build instructions][build].
