We’ve added a ton of new features and improvements in this release:
- Manage your bookmarks easily with a new and colorful tab design
- Huge performance improvements
- Pixel-perfect per-monitor DPI support
Tabs and Header
We implemented a new tab-centric design to increase vertical space and to give readability to the the repository you’re currently working in. The new header design gives you an additional 20px vertically, while the removal of the bookmarks sidebar gives you 250px horizontally.

The New Tab….Tab
The repository browser now lives in the New Tab. The old sidebar crammed repository names and had a confusing relationship to your remote repositories. Now you have a dedicated experience for both in a full window. This approach also frees up more space to focus on code once you’re in a repository.
SourceTree for Windows 2.0 is screaming fast. We improved performance by adding a hybrid LibGit2 handler for most git operations. In many cases, performance for most operations increased by almost 2x. Look how fast reading stashes are with LibGit2!
Many primary feature workflows have been rethought and improved. Compare the steps needed for creating a remote repo in the current version of SourceTree, vs the new workflow. In 2.0, creating a remote repository and managing your remote accounts is front-and-center rather than living 2-3 menus or pop-up dialogs deep.
Before (left) and after
Animations, more vibrant colors, improved contrast, and per-monitor DPI support are just a few of the improvements we’ve made. Note the removal of the Windows 2000 era pinstripes, vivid colors, and branch label readability improvements. We’ve improved contrast in many areas by tweaking our use of gray colors, and added accents to window dialogs and notifications.
Before (left) and after
Per-monitor DPI support
On systems that support per-monitor DPI settings (Windows 10 Anniversary), SourceTree will automatically adjust icons and text to be crisp and pixel perfect when the window is moved between monitors. SourceTree will still use high-DPI icons and scale properly even if your OS doesn’t support per-monitor DPI and you still have a high-DPI monitor or laptop.
Before (left) and after
Readability has been improved on the sidebar, with more spacing between text and increased vertical spacing.
Before (left) and after
Additionally, the ahead/behind indicator will now float on the right-side of the sidebar, and will be visible even if there’s a scroll-bar in either direction.

There have been a few reports of memory leaks in recent versions of SourceTree for Windows. We understand these kinds of issues can adversely affect the SourceTree experience and are important to identify and address.
Identifying the leaky object
How does a memory leak appear? Most of the time it’s a fairly simple case of “I created some objects, and when I was done using those objects something was still referencing them”. In this case, identifying what was leaking in SourceTree was an easy task:
Determining the cause
Most of the time the cause of a leak is easy to spot:
- An event handler is still subscribed
- The object is not being removed from a list or is still held on to as a direct reference
- An unmanaged object wasn’t disposed/cleaned up
owever, the real difficulty isn’t figuring out if you have a leak – . In this case, I suspected that our UI library that quickly draws the sidebar was doing something wrong, and that it might be holding onto objects that it shouldn’t. After looking at the memory dump it was clear that assumption was correct:
more than 4x the correct number of nodes. Okay, so now we know that it involves the SidebarNode and the objects. The TreeNode holds a reference to the object it’s showing to the user, so something must be keeping a reference of it around, which is keeping our massive count of SidebarNodes around too.
After taking a peek into the the TreeNode class, there were a few issues (oops):
- A subscription to an event handler wasn’t unsubscribed
- The TreeNode objects were added to a cache and never removed from that cache
After running the tests, it appeared that the leak was fixed. As mentioned earlier this fix has been rolled out in 1.9.9 for Windows, and should address the memory issues we were seeing. Check it out for yourself!

We’ve been hard at work squashing bugs, fixing crashes, patching and upgrading parts of SourceTree for Windows in version 1.9.9. Remember that annoying memory leak in the TreeView? Patched. Want support for Git LFS 1.5.2? We’ve added that. Feel free to check that Spell Checker checkbox too – we’ve provided safeguards to protect against Windows’ own spellchecker performance issues. Performance when switching tabs have been improved too. And that’s just the tip of the iceberg.
We want to give a big shout out to members of our Beta community. Your participation helps us identify and fix the biggest pain points; thank you! And if you’re interested in joining the beta program you can do so here.

When it comes to rolling out new software updates, the SourceTree team is always looking to deliver a better experience to users with minimal disruption. In the past we an, detailed how we deliver releases, and now . By progressively rolling out updates we aim to deliver new features and functionality to users in a more robust fashion.
What’s the plan?
Where we used to roll a new update to all users on day one, we’re now progressively rolling out updates to users. This staged approach offers granularity during a release, allowing us to scrutinize each update for bugs and showstoppers before it hits critical mass.
The general flow of a build through our release pipeline is common across both Windows and Mac platforms. The below diagram – using our as an example – outlines our process and describes the granularity of our new staged rollout in more detail.
Once a release leaves beta it’s progressively rolled out to groups of users over a period of a few weeks, with time in-between for fixes to be implemented where necessary.
||Available exclusively for
How did we implement it?
The implementation is slightly different for Windows and macOS platforms, but aim to achieve the same goals:
- no dependency changes
- client self-assigns update group
- ability to release in stages (group 1 at 5%, group 2 at 15%, etc.)
- no impact on existing alpha/beta distribution
- minimal file duplication on server
- no need for a self-made web service
- automatable process
Having implemented Squirrel.Windows for SourceTree’s beta program, we’ve decided to move GA releases from AdvancedInstaller to Squirrel as well. Why Squirrel? We were attracted by its focus on simplicity and felt it aligned well with our goal of improving the installation process for users:
Windows apps should be as fast and as easy to install and update as apps like Google Chrome. From an app developer’s side, it should be really straightforward to create an installer for my app, and publish updates to it, without having to jump through insane hoops.
We’ve found it very easy to integrate Squirrel with our FAKE-based build process and CI. The resulting installer is much smaller, quicker to run, has a cleaner footprint, and comes with the added bonus of removing the requirement for Admin rights to install. Overall we felt the user install experience is much improved.
For progressive rollouts, Squirrel comes with built-in staged rollout functionality. SourceTree generates a release percentage for this local install; this defines which part of the release schedule the instance falls into. SourceTree will check at start up for any new updates, or the check can be manually triggered via the Tools/Options/Update tab. After each update, SourceTree will regenerate a new release percentage, ensuring a random distribution of updates.
Important information for Windows users
The switch from AdvancedInstaller to Squirrel will involve a number of changes you should be aware of:
- 1.9.x.x will be the last AdvancedInstaller update and will install as normal
- 1.9.x.x+1 will be the first progressive rollout release AND the first Squirrel release
- 1.9.x.x will detect 1.9.x.x+1 using the new Squirrel progressive rollout process
- 1.9.x.x+1 will be installed as a pure Squirrel install, i.e.
- installation location will move from ‘c:\program files x(86)\Atlassian\SourceTree’ to ‘c:\users\USERNAME\Appdata\Local\SourceTree’
- the new location means installation will no longer require Admin rights
- the new installation will for now still use the same configuration files held under ‘c:\users\USERNAME\Appdata\Local\Atlassia\SourceTree’ so all existing settings will be respected
- The Squirrel Update process does NOT include visible Release Notes before running.
- To uninstall you simply delete the folder
- It is possible to downgrade without uninstalling first, but data integrity of configuration and settings is not guaranteed.
For macOS we weren’t able to find any existing options that met our needs. But Sparkle, the update framework we’re already using, does include a number of hooks for customizing the experience, so we decided to build our own from that. In order to utilize staged updates we only need to take advantage of a single method:
Inside this method we use some randomization to choose groups; that logic is encapsulated in a thoroughly unit tested class (). On launch, a user’s group is assigned and cached, clearing when it’s a new app version (2.3.2 → 2.4, not 75 → 76).
On the Server
What happens on the server end is largely unchanged from what we have today. We’ve added new copies of feeds and tweaked release notes so they work in concert with randomization to make staged updates possible.
- direct download and update zip files – a release is uploaded like normal, access to them is managed by feeds; no duplication necessary
- appcast (update) XML feeds – Appcast.xml stays (legacy, no further updates), AppcastAlpha.xml and AppcastBeta.xml stay the same, adds AppcastGroup0.xml through AppcastGroup5.xml
- release notes – ReleaseNotes.html stays (legacy, no further updates), ReleaseNotesAlpha.html and ReleaseNotesBeta.html stay the same, now we use version specific release notes like 2.3.2.html
Build release process
Unsurprisingly, we continue automating via Fastlane:
fastlane update percentage:50
This former “early access” lane runs a relatively similar process as before: it takes the current version + build info and makes sure the appcast and release notes have been updated properly. If it’s already present no build is produced but the appcasts and release notes are prepared.
Iterating On Our Process
It’s been great revisiting the initial CI and deployment processes we put in place for the beta program and expanding upon them. Figuring out the path of least resistance and what options might work presented a fun challenge and our Fastlane suite is better than ever. Now that we’ve landed this important bit of infrastructure we look forward to the many successful deployments and exciting changes in SourceTree’s future!

A couple weeks ago we shared our beta development process. And If you’ve joined our beta program, you must be thinking, “when is SourceTree going to get to step 4: Early Access?” To elaborate a bit, an Early Access build is a production-ready build which has been tested by you, our Trusted Testers. We want to give you a heads up that will be available for download at www.sourcetreeapp.com in the coming days. Here are a few things to look out for in the update. The following will be available in OS X first, with Windows soon to follow later.
- Attic removed – While working on this upgrade we found that hg-attic, the Mercurial extension SourceTree used for shelving changes, was no longer compatible. SourceTree has now migrated to Mercurial’s built-in shelving implementation. Unfortunately, the two formats are incompatible and this means hg-attic and its contents are no longer supported in SourceTree. However, existing hg-attic shelves are not lost and are listed on the side bar under a new heading “SHELVED BY HG-ATTIC”. They are treated as standard patches with limited functionality to view, import or delete. We recommend applying any hg-attic shelves you have in your repos as soon as possible or convert to the new format by importing and creating a new shelve.
- No support for hgattic extension – From the next release onwards, v2.2.5 on OS X and on Windows, SourceTree will not support hgattic extension and recommend versions of Mercurial 3.7.3 or higher .
- on OS X build – Many of you might have seen errors which include the path “Users/mbasaralusrinivasa/workspace/git-scm/git-274/…”. Well, this is the path at which we installed Git 2.7.4 and was bundled with SourceTree 2.2.4. We had to address the Git security issues quickly and since an officially maintained build of Git was not available at the time, we built it ourselves. We later realized that there were some binaries that referenced the local install path which was visible in some error logs. To fix this, we bundled the (now) official Git 2.8.1 binaries.
If you notice any issues or bugs in the Early Access build, please feel free to file them at jira.atlassian.com. And if you haven’t already, please join our beta program to get access to a ton of features before they are made generally available.

SourceTree Beta 1 is here! Over the past couple of weeks, we’ve announced a beta program and given you a look behind the curtains. The wait is over. Today, those of you who’ve signed up to be a trusted tester will get access to SourceTree Beta 1. In our first beta we’ve addressed:
- Several bug fixes
- Updated icons to include color and increased contrast
- Force Push on Windows
- Improved reliability and localizations on OS X
- Commit Templates with markdown on OS X
- Crash reporting via Bugsplat and Fabric
and get access to new features before they’re made generally available. Thanks for being part of the SourceTree team.

Last week we announced a new beta program for SourceTree, and I want to thank everyone who signed up to be a trusted tester. We received a lot of interest and are in the process of building a few new features and improvements for you to try out. For those who haven’t signed up yet, don’t wait too long. We’re still accepting trusted testers, get in now by signing up here.
we’ll release our first SourceTree Beta and want to give you a look behind the curtains at the testing process, both internal and external, so you can see how the beta program will work.
Step 1: Alpha
SourceTree Alpha is where we turn your feedback in to features that we test internally. SourceTree Alpha will not be available for public download. However, in one off cases, we will reach out to a few trusted testers for early feedback.
Step 2: Blitz!
1 Mississippi, 2 Mississippi, …, BLITZ!!!
Once we determine a set of improvements that are ready for a public release, we will build a b candidate. The beta candidate will go through intensive acceptance testing with our QA team- essentially making the beta candidate feel like a college quarterback on their first day against the top-ranked NFL defense.
Step 3: Beta
All systems go! When the beta candidate passes internal acceptance testing, it’s ready for our beta community to give it a spin. Initially, the SourceTree Beta will be available for download from our public repository and will not replace your production copy. Your version of SourceTree and the SourceTree Beta will be able to run side by side, and each instance will offer updates independent of each other. Beta releases will have features in early preview that may have stability or performance issues so they will be kept separate from production.
The best part of the beta program is the feedback loop. To make feedback reporting seamless for the trusted testers, we’ve implemented Fabric and BugSplat (tools that make crash reporting easy) in SourceTree for OS X and Windows respectively. is to report any issues with the “trusted_tester” via our Trusted Tester Issue Tracker.
Step 4: Early Access
Once we’ve confirmed there aren’t any show stoppers reported by our trusted testers, the most current version of the SourceTree Beta (Early Access build) will be made available for public download via www.sourcetreeapp.com or https://www.atlassian.com/software/sourcetree/overview, rather than prompting users with an in-app update. To get notified about Early Access builds, follow us on Twitter.
Step 5: General Availability
The final stretch! We will take this last week to make sure nothing falls through the cracks before we prompt you with in-app updates. Assuming all systems are pointing to ‘go’, roughly one week after being made available for early access, the last Early Access version of SourceTree will be made .
Sign up to become a trusted tester in the SourceTree Beta
Now that you know the process, we would love you to be a part of it. Our never-ending goal is to make SourceTree the best Git and Mercurial client out there, and we’re only at our best with your contributions and your feedback. So, if you haven’t already, sign up to become a trusted tester today and keep an eye out for the newest updates from SourceTree.

We’re thrilled to launch a new beta release process for our upcoming SourceTree releases. This will give you an opportunity to engage directly with the SourceTree team and provide feedback on future updates. If you’re interested in becoming a trusted tester and would like to get early releases from SourceTree, join this google group. We’re still hammering out the program’s last few details, and will share updates here soon.
We look forward to working with you. Thank you for your support!

Our goal with SourceTree is to move towards a cleaner, simpler interface for developers new to Git while keeping all the powerful features advanced users love. The last release was a step in that direction. We’re excited to share with you our future plans, but first let’s take a step back and look at how far we’ve come:
SourceTree in 2012
SourceTree in 2015
We’ve made huge strides in improving usability and UI consistency throughout SourceTree, but we’re just scratching the surface.
Addressing approachability and “interface bloat”
There’s no doubt that Git has a steep learning curve. SourceTree has always helped by offering an excellent visual counterpart to the command line interface. We don’t “dumb down” Git, but we believe we could do a better job of making SourceTree more approachable for new users.
Many SourceTree users asked us to tackle SourceTree’s “interface bloat”. One way we tackled this problem was with data. By thoroughly looking at the click data, we found a set of buttons that were rarely used in the toolbar. We surveyed roughly 180,000 unique users and found that the “Reset”, “Add”, “Remove”, “Add Remove”, and “Git Flow” buttons, each individually, were used by less than 5% of those surveyed. So we created some new mockups without these buttons in the UI and tested these mockups with our existing users for over six weeks. They loved it!
Don’t worry, we did not remove any functionality, all of those options are still accessible via right click and the “Repository” and “Actions” menus.
Modern design across two platforms
We’re trying to make SourceTree for Windows as beautiful as the OS X App, and we finally approached a point of convergence. Windows users – we promise that a bright future is ahead. Here is a sneak peek:
