Mozilla's Thunderbird is an email client revered by many, and it has been getting a steady stream of updates over the years.

Earlier this year, when they gave us a [sneak peek](https://itsfoss.com/thunderbird-supernova/) at its upcoming folder design changes, we were quite excited to see how Thunderbird would look and perform.

And now, the time has finally come to experience the Thunderbird 115 'Supernova' release. 

## 🆕 Thunderbird 115: What’s New?

### Revamped Toolbar

Called the '**Dynamic Unified Toolbar**', Thunderbird's toolbar now has all the frequently used options placed neatly, with a few options being moved to the level below.

### Redesigned Inbox

The inbox has received a complete revamp **featuring a three-pane window design** with a **new folder pane** with a **decluttered layout** and **new icons**, an **updated message list**, and a **better message display window**.

Looks pretty clean!

### Calendar Redesign

The calendar integration has also received a makeover. It now features a **'mini-month' layout**, **various improvements to the day/week/month grid**, an **updated color palette**, and more subtle changes.

### Improved Menu

Thunderbird now features **a keyboard-accessible menu** that has been redesigned for a faster and easier navigation experience.

They have done away **with the old crowded look**, by opting for fewer submenus, persistent global options, and a consistent look across the menu.

### Density Control

The updated menu also features **new density controls** that allow you to set the perfect density and font size settings for the whole application. 

This **will come in handy in multi-monitor setups**, where text readability can be a major concern over different screen resolutions.

### 🛠️ Other Changes and Improvements

Other than that, Thunderbird 115 features the following changes:

- **Thunderbird can now open external .eml files in a tab**
- **Ability to upload OpenPGP public keys to VKS and HKP keyservers**
- **OAuth2 support for Fastmail**
- **Auto-migration of Office 365 accounts using password authentication to OAuth2**
- **Address book cards now have support for fax and phone number links**

## 📥 Get Thunderbird 115

You can get the latest Thunderbird release from its [official website](https://www.thunderbird.net/?ref=itsfoss.com). Or, you can wait for the update to arrive via your package manager (which can take a bit of time).

**You cannot upgrade from Thunderbird 102**. So, you need to perform a fresh installation to use it.

You can also opt for the [Flatpak](https://flathub.org/apps/org.mozilla.Thunderbird?ref=itsfoss.com) to get the latest version quickly.

📋

If the website is not reflecting the latest version yet, you can head to its [FTP portal](https://ftp.mozilla.org/pub/thunderbird/releases/115.0/?ref=itsfoss.com) and get the binaries you need. Or, you can choose to wait for them to update the official website.
