Blender 4.4.1 was released on April 15, 2025, as a corrective update to Blender 4.4. It focused on bug fixes and stability rather than introducing a new feature generation. Release notes report 108 fixes, including problems affecting Grease Pencil, Rigify, NLA, Cycles, sculpting, asset search, localization, and selection.
It is no longer the newest release in the 4.4 branch: Blender 4.4.3 arrived on April 29, 2025. Unless you need the exact 4.4.1 build for compatibility or reproducibility, evaluate 4.4.3 instead. For long-running production work, Blender 4.2 LTS may be the more appropriate choice.

- 4.4 identifies the feature-release branch.
- .1 identifies the corrective patch release.
It is not Blender 4.1, a separate product, or a new feature release comparable to Blender 4.3 or 4.4. The major feature story belongs to Blender 4.4; version 4.4.1 addresses issues discovered after 4.4.0.
Release date and support status
Blender 4.4.1 was released on April 15, 2025. A translated corrective-release summary attributes 108 fixes to the update. Blender 4.4.3, released on April 29, 2025, is a later patch in the same branch.
Blender 4.4.1 is not an LTS release. Blender 4.2 is the LTS branch associated with this release generation. The practical distinction is simple:
- Choose the 4.4 branch for its newer feature set.
- Choose Blender 4.2 LTS when long-term maintenance and predictable deployment matter more than newer features.
- Do not describe Blender 4.4.1 as a stable LTS version.
What Blender 4.4.1 fixed
The fixes are most useful when considered by workflow rather than as a long issue-number list.
What’s actually slowing this PC down?
Pick the symptom - the matching free tool is one click away.
Animation, rigging, and actions
The corrective release addressed crashes in Rigify during bone-rotation conversion, along with NLA and slotted-action problems. These issues matter most to character-animation workflows and scripted animation pipelines. They do not mean that every animation project will behave differently, but they can make a narrow operation fail severely for affected files.

Grease Pencil
Reported fixes included Grease Pencil crashes involving empty layers and the Merge Group operation. Artists using Grease Pencil should test the operations that are central to their files rather than assuming that every Grease Pencil scene needs conversion.
Modeling and sculpting
Blender 4.4.1 fixed a remesh modifier crash during numeric input and a display problem when cancelling Sculpt Transform. These are particularly relevant when interactively editing dense meshes or entering modifier values during a modeling session.
Cycles and viewport display
The release addressed Cycles viewport and reference-image display problems. A display correction is not the same as a performance improvement: there is no basis for assuming that 4.4.1 renders faster than 4.4.0.

Scan for outdated or missing drivers - takes under a minuteDriver Scan →Clear out junk files and repair common Windows errorsFree Scan →Fix the driver behind crashes, sound loss and screen glitchesFind Drivers →Blender 4.4 also introduced compatibility changes affecting Cycles GPU rendering, including higher minimum driver requirements for some AMD and Intel configurations. That is a branch-level consideration, not necessarily a new 4.4.1-only requirement. The relevant requirement depends on the GPU vendor, operating system, rendering backend, and installed driver.
Assets, search, and localization
Fixes covered asset search and reload behavior, as well as text-editing problems in files translated into Chinese. These issues may be invisible in a simple modeling test but important in asset-heavy libraries, localized installations, and team workflows.

Selection and clipping
Selection failures inside a clipping region created with Alt+B were also addressed. If your work depends on clipping-region selection, test that operation directly in a copy of the project.
The full corrective-release information is available in the release summary. The 108-fix figure should be understood as the count reported there, rather than as a claim that every possible Blender issue was resolved.
Should you upgrade from Blender 4.4.0?
| Situation | Best approach |
|---|---|
| You want the latest patch in the 4.4 branch | Evaluate Blender 4.4.3 rather than 4.4.1. |
| You need to reproduce a historical project or deployment | Use the exact 4.4.1 build. |
| A known 4.4.0 bug affects your workflow | Update after testing the affected operation. |
| You are close to final delivery | Keep the working version and delay a production-wide change. |
| You rely on unsupported add-ons or scripts | Validate compatibility before updating. |
| You need a long-lived studio environment | Evaluate the applicable LTS branch, including Blender 4.2 LTS. |
For most users already committed to Blender 4.4, moving from 4.4.0 to a later corrective release is sensible. However, 4.4.3 is the normal choice today when exact 4.4.1 compatibility is not required. A patch release can fix crashes without making every add-on, script, cache, or render result interchangeable.
Blender 4.4.1 versus Blender 4.4.3
Both versions belong to the 4.4 feature generation, but 4.4.3 is later. Use 4.4.1 when a studio, plug-in, classroom, render farm, or reproducibility requirement explicitly names that version, or when you are investigating a historical behavior between 4.4.0 and 4.4.1.
Use 4.4.3 when you simply want a mature 4.4 installation and have no reason to reproduce the earlier patch. Before switching, check the add-on author’s supported versions and test any pipeline-specific behavior.

Blender 4.4.1 versus Blender 4.2 LTS
Blender 4.4.1 offers the 4.4 branch’s newer features, while Blender 4.2 LTS is designed for users who value a longer maintenance horizon. An LTS branch is often easier to validate across a studio because teams can avoid frequent feature-branch changes.

Independent reader supportYour contribution helps us test, update, and keep practical guides available for everyone.Compatibility with files, add-ons, and scripts
Blend files
Do not assume that files behave identically across Blender versions. Version changes can affect data, modifiers, simulations, node evaluation, and other elements of a scene. Saving a file in a newer version can make returning to an older version difficult or impossible without a backup.
Before testing 4.4.1 or 4.4.3:
- Duplicate the
.blendfile. - Preserve the original Blender installation.
- Back up linked libraries, textures, caches, simulations, and output settings.
- Test the copy before saving the production file.
Add-ons and Python
Blender 4.4 introduced compatibility-sensitive changes involving Actions, Sequencer strips, Blender type subclassing, and Python API behavior. A corrective release may fix a Blender crash but cannot automatically make an older add-on compatible with the 4.4 API.
A safe migration sequence is:
- Back up the project, preferences, startup files, and add-on installers.
- Install 4.4.1 or 4.4.3 alongside the existing version.
- Test the add-on in a duplicate project.
- Check the vendor’s stated Blender-version support.
- Run automated scripts from a clean command-line invocation.
- Keep the previous executable available for rollback.
Blender’s 4.4 release notes document the branch-level compatibility changes.

How to install Blender 4.4.1 safely
- Back up the project. Keep the original
.blendfile untouched. - Preserve the current installation. Do not overwrite the only known-good Blender executable.
- Download from Blender’s archive. Use the previous-versions page or the official Blender 4.4 archive.
- Select the correct build. Check the operating system and architecture. Available platform categories can include Windows installer or portable ZIP, Windows ARM, macOS Intel, macOS Apple Silicon, Linux, and source code; exact archive contents can change.
- Test preferences and add-ons. Confirm that required extensions load and that their versions are supported.
- Open a project copy. Check links, textures, modifiers, simulations, compositing, and exports.
- Compare a known test scene. Check render engine, GPU or CPU device, color management, resolution, sampling, and output.
- Adopt it only after validation. Keep the old executable, preferences, caches, and test scene for rollback.
Blender’s release guidance also provides a bug-report route through Help → Report a Bug. Use it for reproducible Blender problems after checking whether an add-on or local configuration is responsible.
Common problems after upgrading
An add-on disappears or fails to load
- Check the author’s supported Blender versions.
- Look under Edit → Preferences → Add-ons.
- Confirm that the add-on was installed for the Blender version you launched.
- Test with a clean preferences directory.
- Consider whether a Python API change, rather than installation, caused the failure.
Assets are missing
Work from a duplicate file, then use File → External Data → Find Missing Files and select the project’s asset directory. Confirm that paths are correct before repacking or relinking anything. Keep the original project unchanged until the result is verified.
Rendering changes
Compare the render engine, GPU or CPU device, color-management settings, resolution, sampling, driver version, linked libraries, and textures. Save a known test scene and compare output before deploying the update to a team or render farm.
Blender crashes at launch
Try factory settings, temporarily disable recently installed add-ons, test the official portable build where available, or move back to the previous known-good version. Avoid deleting configuration data before preserving a copy.
Recommended Free Tools
A file will not return cleanly to the older version
Use the untouched backup rather than relying on an older Blender version to reverse every change. This is why versioned project copies and retained executables are essential for production work.
Where to download Blender 4.4.1
Use Blender’s official sources:
Do not substitute 4.4.3 for 4.4.1 without telling your team or documenting the change. Conversely, do not install an unofficial repackaged installer merely because it is easier to find. Check the archive for the correct operating-system and architecture package, and verify checksums where provided.
Final verdict
Blender 4.4.1 was a legitimate corrective release that fixed 108 reported problems across several workflows. It is worth considering if you are pinned to that exact version or if a documented 4.4.0 problem affects your work.
It is not the default download for most users now. Choose Blender 4.4.3 when you want the later 4.4 patch, and evaluate Blender 4.2 LTS when long-term production stability matters more than the newest 4.4 features. Whichever version you choose, install it alongside the working build, test a copy of the project, and keep a rollback path.
