Summary

Two related pieces of the 1.5.0 release: the extraction/CI hardening work, and a new visual identity replacing the pre-redesign gradient logo.

Security and robustness

  • Column-detection histogram rebuilt on a difference array: O(items + size) instead of O(rows x size), so a crafted PDF with thousands of sparse rows across a wide coordinate range no longer freezes the tab
  • Fragment merging skips rows with more than 400 fragments (the containment scan is quadratic)
  • Excel exports mark formula-leading cells with the Text number format, so an in-place edit cannot silently convert them into live formulas
  • check-cdn-versions.sh now fails on a missing/invalid SRI attribute, a missing crossorigin, or mismatched digests for the same asset
  • Renovate no longer auto-merges Actions digest repoints; they now require dependency-dashboard approval
  • Note: an Egret CI integration was trialed and removed for now - GitHub-hosted runners trip a false positive on the Azure wireserver IP (False positive: Azure wireserver (168.63.129.16) flagged as raw-ip egress on GitHub-hosted runners Egret#10); it returns once that is fixed upstream

Identity

The previous logo was a blue-to-green gradient that predated the Feb 2026 monochrome redesign. It is replaced by a grid monogram - table cells arranged into an "E" - in the existing palette (#18181b ground, #fafafa cells, one #a1a1aa accent cell), no gradients.

  • easyconvert-icon.svg (app tile, maskable) and easyconvert-logo.svg (header mark, transparent)
  • PNG favicons at 16 and 32, Apple touch icon, and 192/512 PWA icons
  • og-image.png (1200x630) plus OpenGraph and Twitter card metadata, for shared links and the GitHub social preview
  • _worker.js allowlist corrected: it listed /icons/icon-192x192.png and /icons/icon-512x512.png, paths that never existed on disk

Testing

  • Extraction: unit harness plus end-to-end runs against generated LTR and RTL (Hebrew, mixed-direction) PDFs with pdfjs-dist 3.11.174 - all pass
  • Histogram rewrite verified equivalent to the previous implementation across 300 randomized tables (identical output)
  • DoS inputs: 3000 sparse rows over a 43k-pt range completes in ~9ms; a 5000-fragment row in ~1ms
  • Excel export round-tripped through SheetJS: formula-leading cells stay inert literal text, values intact, all cells string-typed
  • Assets served locally: every allowlisted path returns 200, manifest/sw/worker parse clean, check-action-pins.sh and check-cdn-versions.sh pass

Manual step after merge

GitHub's social preview image can only be uploaded through the web UI: Settings > General > Social preview > Upload, using public/og-image.png.

Warning

Review limit reached

@NX1X, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 40 minutes

Enable usage-based reviews in Billing to review now. Otherwise, wait until the next included review is available.
You're only billed for reviews past your plan's rate limits ($0.25/file).

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.
