What is LibreCAD?

Half of LibreCAD's release feed isn't releases — it's download links and nightly builds.

LibreCAD's releases page mixes three different things: actual versioned releases, a rolling Release Candidate tag that gets re-cut for single commits, and permanent entries that exist to keep download links and the latest master build visible at the top of the page. The real releases in this window are 2.2.1.5 in May, focused on translations and bug fixes, and 2.2.1.4 in March, which fixed file associations and copy-paste scaling.

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.

Half of LibreCAD's release feed isn't releases — it's download links and nightly builds.

◆ Current state

LibreCAD's releases page mixes three different things: actual versioned releases, a rolling Release Candidate tag that gets re-cut for single commits, and permanent entries that exist to keep download links and the latest master build visible at the top of the page. The real releases in this window are 2.2.1.5 in May, focused on translations and bug fixes, and 2.2.1.4 in March, which fixed file associations and copy-paste scaling.

◆ Where it's heading

The 2.2.1.x line is in pure maintenance: crashes, rendering accuracy, packaging and internationalization, with contributions concentrated in a small group of maintainers. Nothing in this window points at 2.3 or at new drafting capability. The more useful observation for anyone tracking the project is that release-feed volume here overstates activity, since a re-tagged release candidate carrying one commit looks identical to a real release from outside.

◆ Prediction

The pattern points to further 2.2.1.x maintenance releases gathered from accumulated fixes and translation updates; nothing in these entries indicates work on a next minor version.

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.
