EnglishWhere to Find the Latest Emgu CV Releases and Change Logs
Updated
The latest Emgu CV release is Emgu.CV-4.13.0, published on 2026-05-20 and available on GitHub and NuGet. Each release announcement on the EMGU site's Latest News section links to its change log and known issues, and older releases are listed in the News Archive.
Where releases are published
Emgu CV ships through two channels, and the release notes point to both:
- GitHub — source code and release artifacts
- NuGet — the package you add to a .NET project
The announcement for each version names both channels, so you can pick the one that matches how you consume the library.
Recent release history
The Latest News section lists releases with their dates. The most recent entries:
| Version | Release date |
|---|---|
| Emgu.CV-4.13.0 | 2026-05-20 |
| Emgu.CV-4.12.0 | 2025-10-04 |
| Emgu.CV-4.11.0 | 2025-07-27 |
| Emgu.CV-4.10.0 | 2025-01-21 |
| Emgu.CV-4.9.0 | 2024-05-12 |
| Emgu.CV-4.8.0 | 2023-09-10 |
| Emgu.CV-4.7.0 | 2023-04-23 |
| Emgu.CV-4.6.0 | 2022-10-30 |
Earlier versions (4.5.5 back to 4.5.1, dated 2022-01-09 through 2021-01-24) appear in the same list, and the News Archive holds release information older than that.
How to check what changed before upgrading
Each release entry includes links to the change log and known issues. Use them in this order:
- Open the change log for the target version and scan for changes affecting the APIs you call.
- Check the known issues list for that version to see whether any open problem overlaps with your use case.
- If you are jumping several versions, read the change logs for each intermediate release, since breaking changes may be documented only in the version where they were introduced.
Practical notes
- The release cadence is irregular — roughly two to four releases per year in the recent history above — so check the Latest News page rather than assuming a fixed schedule.
- Version numbers track the underlying OpenCV line (4.13.0, 4.12.0, and so on), which helps when matching Emgu CV against OpenCV documentation.
- The site does not state pricing or licensing terms for downloads on this page; the platform comparison table separately notes that the open-source Windows build is GPL-licensed while a commercial optimized build exists. Confirm licensing for your distribution scenario before shipping.
