 # Changelog
 
+## 2020.1 (7)
+This is the first update since WWDC and the introduction of iOS 14. As such, most of the focus has been on fixing iOS 14-specific problems. However, there are still a couple new features, both for those on the iOS 14 beta and those not.
+
+Features/Improvements:
+- Add toggle between Posts, Posts and Replies, and Media on user profiles
+  - Remove 'Show Replies in Profiles' preference
+- Limit link preview animation to only link text
+- Add additional context menu actions for statuses, accounts, and hashtags
+- Add semi-translucent background to image descriptions, so they're legible against light images
+- iPadOS 14: Add sidebar
+  - When using multitasking on iPad and switching in and out of "compact" mode, the active tab as well as the navigation history for all tabs will be transferred between the sidebar and tab bar modes.
+- iOS 14: Use context menus on status/account '...' buttons
+- iOS 14: Replace 'More' status swipe action with 'Share'
+
+Bugfixes:
+- Fix crash when attempting to change post visibility on iPad
+- Fix attachment view corners not being rounded
+- Fix crash when viewing instance public timelines
+- Fix Preferences button not appearing on My Profile tab
+- Fix tapping current tab bar item not scrolling to top
+- Fix crash showing audio attachments on Mastodon
+- Fix timeline refreshing forever
+- Set app category (fixes usage not being categorized correctly under Screen Time)
+- iOS 14: Fix crash when searching for instances
+- iOS 14: Fix crash when displaying accounts with no pinned posts
+- iOS 14: Fix crash when displaying search results
+
 ## 2020.1 (6)
 This is the pre-WWDC update with lots of bugfixes and some small features. There will likely be another build this week to fix any pressing issues that arise from iOS 14.
