Natron vs OpenEXR: at a glance
What is Natron?
Natron's last real release was 2024, and the feed since then is build infrastructure.
The most recent item in Natron's release feed is not a release at all — it is a pacman repository of MinGW build packages used to compile the compositor on Windows. Before that, the last substantive publication was a 2.5.1 pre-release in September 2024 carrying Qt deprecation cleanup, UNC path support and rendering fixes. The 2.6 line exists only as a 2023 test snapshot for Apple Silicon that was posted asking users whether it starts.
What is OpenEXR?
A second IDManifest flaw lands two weeks after OpenEXR's forty-CVE sweep
OpenEXR's recent history is dominated by security response. On 2026-08-05 three branches were tagged within two minutes — v3.4.14, v3.3.13 and v3.2.11, fixing 15, 15 and 10 CVEs from one fuzzing and audit campaign, all memory corruption reachable by opening a crafted .exr file. Two weeks later v3.4.15 and v3.3.14 fix two further memory-allocation issues, this time confined to the code that decodes the idmanifest attribute, with CVEs requested but not yet assigned. The 3.4 tag also carries a missing Windows export and reduced compiler warnings in example code.

Natron
0.0DESIGN
Natron's last real release was 2024, and the feed since then is build infrastructure.
◆ Current state
The most recent item in Natron's release feed is not a release at all — it is a pacman repository of MinGW build packages used to compile the compositor on Windows. Before that, the last substantive publication was a 2.5.1 pre-release in September 2024 carrying Qt deprecation cleanup, UNC path support and rendering fixes. The 2.6 line exists only as a 2023 test snapshot for Apple Silicon that was posted asking users whether it starts.
◆ Where it's heading
This reads as a project sustained by maintainers keeping it compilable rather than one being developed. The through-line across the last several years is platform survival: off Python 2, off Qt4, onto Apple Silicon, onto compilers that default to C++17 — each change forced by the environment moving underneath it rather than chosen. Known issues listed in 2021 releases, including silently stalling renders, are still listed unchanged in later ones.
◆ Prediction
Nothing in this feed indicates active feature development or a dated 2.6 release; the recent activity is build tooling, so the most likely next publication is another packaging or CI artifact rather than a user-facing version.
OpenEXR

A second IDManifest flaw lands two weeks after OpenEXR's forty-CVE sweep
◆ Current state
OpenEXR's recent history is dominated by security response. On 2026-08-05 three branches were tagged within two minutes — v3.4.14, v3.3.13 and v3.2.11, fixing 15, 15 and 10 CVEs from one fuzzing and audit campaign, all memory corruption reachable by opening a crafted .exr file. Two weeks later v3.4.15 and v3.3.14 fix two further memory-allocation issues, this time confined to the code that decodes the idmanifest attribute, with CVEs requested but not yet assigned. The 3.4 tag also carries a missing Windows export and reduced compiler warnings in example code.
◆ Where it's heading
The pattern is now established: findings arrive from a continuing fuzzing effort and are patched simultaneously across every supported stream, with the release notes written to tell integrators precisely which code paths are reachable. The narrowing scope is the useful signal — August's first batch spanned the C++ libraries, the command-line tools and the Python bindings, while this one touches only idmanifest decoding and explicitly states other code is unaffected even on files carrying the attribute. Both new tags are release candidates dated ahead of their tagging, and the 3.3 backport reuses the 3.4 note verbatim, down to naming v3.4.15 in its own body.
◆ Prediction
Expect the requested CVEs to be assigned identifiers and the two RCs to be promoted to final tags, with a matching 3.2 backport if the idmanifest code is present in that stream. Further attribute-parser findings are likely while the fuzzing campaign continues.
