202618 releases

  1. Squeeze 1.8.3.1Latest

    • Fix: do not flush all output buffers on shutdown — preserves page-cache buffers and avoids holding the response open after HTML output

  2. Squeeze 1.8.3

    • Optional anonymous usage telemetry (off by default): opt-in under Settings → Squeeze or the one-time Squeeze admin notice
    • Feature events (e.g. settings_saved option snapshot on Save, bulk/single/upload squeeze, upgrade UI) via first-party telemetry.pluginarium.com → PostHog EU — no image bytes, filenames, or media URLs
    • Settings toggles are not reported until Save Changes; restore-defaults is flagged separately — see Privacy

  3. Squeeze 1.8.2

    • Resize originals (max width/height) is free for everyone, including oversized-thumbnail cleanup after resize
    • Settings presets: WebP storage, Blog, and Max quality one-click recipes on Basic settings
    • Environment hints on Squeeze settings when Elementor, Gravity Forms, or WP Offload Media / CDN mapping is relevant
    • HEIC/HEIF: convert iPhone photos in the browser on upload — JPEG normally, or straight to WebP with your WebP quality when Direct WebP is on

  4. Squeeze 1.8.1

    • Security: require upload_files (and edit_post for the target attachment) on restore and related media AJAX actions — nonce alone is not authorization (CVE-2026-110029, reported by Naoki Kawahigashi)
    • Security: stop localizing the Squeeze AJAX nonce on admin/editor screens for users without upload_files

  5. Squeeze 1.8.0

    • Squeeze form uploads: compress visitor images in the browser on Contact Form 7 file fields (free) and Gravity Forms single-/multi-file fields (Premium); separate Basic Settings checkbox from Squeeze on upload
    • Soft megapixel limits and single-thread AVIF on low-RAM devices to reduce browser OutOfMemory on mobile / shared hosting
    • Huge uploads: skip after-upload thumbnail re-squeeze; mark attachment as client-compressed; optionally write the full-size WebP sidecar when sidecar mode is on
    • Plupload multipart markers (_squeeze_client) so precompressed uploads are recognized on add_attachment
    • Console timing summary table at the end of Bulk / upload runs ([Squeeze timing])
    • Bulk savings totals on Media → Squeeze Bulk Tools (tracked since 1.8.0) and a completion summary after each run
    • Admin UX: Squeeze Bulk Tools naming, clearer savings messaging, Upgrade UTM links; DE/ES/FR translations

  6. Squeeze 1.7.17

    • Fix WordPress.org automated review block: emit WebAssembly codecs as separate .wasm files instead of inlining them as multi-megabyte JavaScript lines

  7. Squeeze 1.7.16

    • Directory Squeeze: write .bak backups when Backup original is on; restore in place via “Restore backups in selected folders”; skip *.bak.* when scanning; block Media Library year/month folders (use Bulk Media Library Squeeze instead)
    • Direct WebP (Directory Squeeze): backups are .bak.webp beside the live WebP (same as Media Library); original JPG/PNG twins are removed more reliably after conversion
    • Direct WebP defaults: align stored options with the Direct WebP UI on fresh installs / when both delivery flags were off so bulk Directory Squeeze actually writes WebP
    • Settings / bulk UI: note that with Direct WebP and Backup original on, backups are WebP (e.g. photo.bak.webp)
    • Instant Images: squeeze imported stock photos after attach when Squeeze on upload is enabled (Media Library page, media modal, editor sidebar)
    • Media Library / attachment modal: refresh file-size labels after Squeeze, Re-Squeeze, or Restore (including Premium comparison)
    • WebP Express incompatibility notice is skipped when Direct WebP is already on
    • Admin assets: cache-bust script ?ver= with filemtime after rebuilds; load media-views on the Bulk Squeeze page so hooks attach reliably

  8. Squeeze 1.7.15

    • Cap bulk concurrency by device memory (not raw CPU cores) to reduce WebAssembly OutOfMemory errors on low-RAM devices
    • Lazy-load image codecs in the worker so JPEG-only jobs do not load AVIF/WebP/PNG WASM up front
    • Reuse a small worker pool instead of creating a new Worker per image
    • Force single-threaded AVIF encoding on low-memory devices; add megapixel guard and clearer OOM error messages
    • When max width/height resize is set, downscale during decode (createImageBitmap) and apply the megapixel guard to post-resize size

  9. Squeeze 1.7.14

    • Fixed admin UI layout in RTL languages (logical CSS insets instead of left/right)
    • WordPress 7.1: disable core client-side media processing while Squeeze on upload is enabled, so Gutenberg uploads keep Squeeze quality, Direct WebP, backups, and thumbnail overwrite
    • Gutenberg: intercept only create uploads to /wp/v2/media (skip sideload/finalize)
    • HEIC/HEIF: on-upload conversion added in 1.8.2; older releases left HEIC unsqueezed (turn Squeeze on upload off for WordPress 7.1 core HEIC / HDR)

  10. Squeeze 1.7.13

    • Fixed: “Bulk Squeeze from a Page” now compresses Media Library thumbnail sizes and marks attachments as squeezed (previously only the original was written when process=path)
    • Fixed: fatal error on the Settings page when checking WP Offload Media compatibility (SqueezeOffloadMedia class not loaded yet)

  11. Squeeze 1.7.12

    • Fixed: after resizing an original image to max width/height, thumbnail sizes that are now larger than the resized original are deleted instead of being left on disk
    • Added optional “Delete plugin data on uninstall” setting (off by default) to clear Squeeze options, stats, and related postmeta when the plugin is removed
    • Fixed: “Bulk Squeeze from a Page” now recognizes offloaded/CDN-hosted images via the shared media URL resolver (WP Offload Media and related filters)
    • Fixed: background images and other page images at a specific size are compressed in place when not found in the Media Library, instead of only attempting a guessed original filename
    • Fixed: “Rewrite src to WebP URLs in HTML” falls back to the base WebP sidecar when a sized WebP file is missing
    • Security: reject non-image extensions in per-size AJAX thumbnail uploads

  12. Squeeze 1.7.11

    • WP Offload Media: added a same-origin image proxy so the Web Worker can fetch CDN-hosted images for compression without CORS errors (works even when “Remove Local Files” is enabled)
    • WP Offload Media: thumbnail sizes with no local original on disk (offloaded) are now compressed and uploaded correctly
    • Failed compression state is tracked per attachment — “larger than original” images show a warning with Restore and Re-Squeeze options; changing compression settings clears failed state so images can be retried
    • Excluded images are now omitted from Bulk Squeeze and the Media Library “Non Squeezed Images” filter
    • Bulk Squeeze skips a failed image and continues with the rest instead of retrying the same failure
    • Security: upload format validation now uses a hardcoded allowlist; settings saves require manage_options; unknown option keys are stripped on save
    • Fixed: upload errors now show readable messages (including HTTP 413 payload-too-large guidance) instead of [object Object]
    • Fixed: compression comparison table no longer breaks when an original size is missing from disk

  13. Squeeze 1.7.10

    • WP Offload Media: added incompatibility notices in the WebP delivery settings — the “Keep JPEG/PNG URLs — server serves WebP” and “Rewrite src to WebP URLs in HTML” modes do not work with WP Offload Media; the Direct WebP mode is recommended and works automatically
    • WP Offload Media: provider/CDN base URL is now auto-detected so Squeeze can download images from external storage for compression (no CORS issues)
    • Fixed: “Restore original image” button was missing after a failed compression (result larger than original) when a backup exists — button is now always shown when a backup is available
    • Fixed: clicking “Restore original image” no longer throws a JS error when the image was in the “larger than original” failed state
    • Combined the two-line “Could not compress” error into a single message with an inline link to compression settings

  14. Squeeze 1.7.9

    • Redesigned WebP delivery settings with three clear modes: Direct WebP, separate squeeze-webp folder with URL rewrite, and separate folder with server-side delivery (.htaccess)
    • Voxel theme: pre-upload compression for create-post and file/gallery field uploads
    • CDN URL setting (Premium): works with all WebP delivery modes, including Direct WebP
    • Improved URL-to-filesystem resolution when checking WebP files (CDN-aware, Premium CDN URL)
    • Bulk directory browser returns site-relative paths only (no absolute server paths in API responses)
    • Fixed Media Library bulk squeeze completion popup (missing JavaScript helper import)
    • PHPUnit and bulk browse path handling improvements
