Polar 1.60 and 1.50 Release Update

Polar 1.60 and Preparing for 2.0

Another big release is out to help prepare us for 2.0.

Most of the changes here are small to moderate features and improving stability but there have also been a lot of library
updates too which were important.

Prompting for Premium and Locked Features

One of the big changes in this release is that we're now requiring that users upgrade for features in premium
for which (in the past) we weren't requiring an upgrade.

This might mean at this point you will need to upgrade to premium if you depend on one of these features.

Features

The sidebar no longer shows the color for the buttons unless you hover over them. The colors
are also more muted to help not distract more when using the annotation sidebar.

Flashcards stats in the mobile app now work. This way you can do a review and them immediately see the size of your
queue and also the number of tasks completed.

Ability to revise the text of a text highlight. This was requested by a number of users due to some annotations
having hyphens or errors in representation of mathematical formulas.

Big refactor of the context menu so that range selection and context menus work properly.

Multi-selection for deletes implemented.

The context menus now have icons

Ability to remove items from folders via right click

Bronze now officially required for reading stats and recommended tags

Major refactor of how text selection works using the new modern text layer code in pdf.js which has
been a major complaint since 1.0. Excited to finally have this fixed!

Fixes
