Horizon EDA vs OpenEXR

Horizon EDA vs OpenEXR: at a glance
What is Horizon EDA?
Horizon EDA ships one feature release a year and spends the rest fixing what it broke.
Horizon EDA runs a slow, deliberate cadence: roughly one named feature release per year — Kepler in 2023, Luna in 2024, Mirage in 2025 — followed by two bugfix releases in the same series. The 2.7 series added pick-and-place export save/load, polygon pad rendering performance, project pool cache updates from the editors, and parameter fixing in the package editor. Its two patch releases were crash fixes and export correctness, mostly around silkscreen and PDF output.
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.

Horizon EDA
0.0DESIGN
Horizon EDA ships one feature release a year and spends the rest fixing what it broke.
◆ Current state
Horizon EDA runs a slow, deliberate cadence: roughly one named feature release per year — Kepler in 2023, Luna in 2024, Mirage in 2025 — followed by two bugfix releases in the same series. The 2.7 series added pick-and-place export save/load, polygon pad rendering performance, project pool cache updates from the editors, and parameter fixing in the package editor. Its two patch releases were crash fixes and export correctness, mostly around silkscreen and PDF output.
◆ Where it's heading
The feature work tracks a single theme across all three named releases: making the editors forgiving. Undo and redo that never forgets, undo/redo of selection, sticky selection and configurable selection modifiers arrived in 2.5 and 2.6; 2.7 pushed into export workflows and rendering speed. The bugfix pattern is consistent too — most patches land in the board editor, which is where the complexity lives.
◆ Prediction
On the established cadence a 2.8 feature release is due, and the recent bugfix concentration suggests export and silkscreen handling get attention in it.
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.
