Release Notes

1.3.4 - 2023-11-28

Fixed

• Significantly improved Aztec Code recognition rates for full-range codes.

• Removed transmission of unused URL parts in license verification and usage tracking.

1.3.3 - 2023-11-07

Fixed

• Fixed an issue on iOS where camera access failed with a camera device is not compatible error message rememberCameraDeviceId was set to true and the user's device changed, leading to the remembered camera device id no longer being valid.

Changed

• Expose detail message when license check fails, providing potentially useful information on how to resolve the issue (e.g. URL not in scope).

Added

• Throw a dedicated error if the SDK is initialized in an insecure context (non-HTTPS, non-localhost). Previously this was reported in a confusing fashion (invalid license).

1.3.2 - 2023-10-26

Fixed

• Fixed an issue that led to offline-capable license keys being reported as expired.

1.3.1 - 2023-10-14

Added

• Added configuration option focusOnTap (default: true) to overlay configuration: this toggles the autofocus that occurs when tapping on the overlay. Previously focusing on tap was always enabled.

Changed

• Adapted license service calls in order to re-enable detailed usage stats in Customer Portal using Client Hints. No changes to existing Content Security Policies are necessary.

1.3.0 - 2023-09-20

Added

• New configuration option rememberCameraDeviceId in frame source configuration: if set to true, the SDK will remember the selected camera device after a successful scan, and attempt to re-acquire it when re-initialized. Default value is false.

• Support for PDF417 and Compact PDF417 symbologies is now available, the new symbology can be activated by specifying pdf417 in the symbologies array of the engine configuration. PDF417 barcodes can only be read in horizontal direction at the moment.

Changed

• Under the hood improvements and removal of legacy code.

1.2.2 - 2023-08-16

Added

• Extended support for inverted codes to 1D barcodes. Setting invertedCodes to true will now also cause inverted 1D barcodes to be read.

• New helper method StrichSDK.hasCameraDevice() to check for the existence and availability of a camera device.

1.2.1 - 2023-07-28

Added

• Raw code data is now exposed through the rawData property of the CodeDetection.

1.2.0 - 2023-07-12

Added

• The GPU-accelerated barcode locator is now based on WebGL 2, which is widely supported by now. If you are for some reason required to use WebGL 1, set the new impl field on the locator configuration to webgl1. WebGL 2 supports asynchronous reads which we use to decrease the load on the main thread. Some older Safari versions have reported issues using the asynchronous reads, which is why for the moment we have disabled asynchronous reads on iOS. This will likely change in the future.

Fixed

• Fixed a rare engine crash that resulted from incorrect error handling.

Changed

• Changed the default values for hysteresisMinCount to 2 and hysteresisInterval to 350. The previous defaults were causing EAN/UPC codes to be unreadable on low-end Android devices.

1.1.4 - 2023-06-26

Added

• User-facing error messages (e.g. "Access to camera not permitted") are now localized. English, Spanish, German, French and Italian are the currently supported languages, with more to come.

• Prepared support for iOS 17 Safari OffscreenCanvas+WebGL support. STRICH will utilize a GPU-accelerated OffscreenCanvas if the browser supports it.

Fixed

• Improved performance when scanning EAN/UPC codes with hysteresis enabled.

1.1.3 - 2023-06-07

Added

• Configurable min/max length for variable-length symbologies. Instead of just the name, specify an object with name, minLen and/or maxLen in the symbologies array. Example: symbologies: ['ean13', { name: 'code128', minLen: 8, maxLen: 12 }]

Fixed

• Removed a stray console output statement that was meant for debugging purposes only.

1.1.2 - 2023-06-06

Fixed

• Improved error handling when encountering OverconstrainedError, especially on Firefox desktop. Special thanks to Jukka Aittokallio for reporting the issue.

1.1.1 - 2023-05-22

Added

• Added hysteresis for 1D barcodes with weak checksums (EAN/UPC symbologies) to decrease misreads. This feature improves reliability for EAN/UPC barcodes at the cost of slightly slower detection, and can be deactivated by setting the new hysteresisMinCount engine parameter to 0.

Fixed

• Fixed a memory violation in the Databar decoder, which would occasionally crash the engine.

1.1.0 - 2023-05-17

Added

• Added experimental support for EAN-2/EAN-5 supplements (new ean2 and ean5 symbology options). Note that this feature is experimental: supplemental symbologies will not be enabled if you enable all symbologies (which we do not recommend).

• Added an optional onError callback to the BarcodeReader instance.

1.0.9 - 2023-05-15

Fixed

• Fixed an issue where an error in the WebAssembly engine was misinterpreted, and wrong results where generated.

• Do not draw the red 'laser line' when a 2D symbology is scanned

1.0.8 - 2023-05-11

Added

• Not calling BarcodeReader.destroy() after no longer needing a BarcodeReader is a common cause of camera access errors. A warning is now logged to the browser console if a BarcodeReader is initialized when another instance remains that was not destroyed yet.

• If no regionOfInterest is specified in the configuration, an appropriately sized region will now be automatically selected based on the configured symbologies.

Fixed

• The horizontal targeting line in the scanning overlay was not being shown if all symbologies were enabled.

1.0.7 - 2023-05-06

Fixed

• When a BarcodeReader was used in standalone display mode on iOS (PWA, added to home screen), camera access was lost when the user unfocused the PWA. An error is now displayed in this case, along with a button to resume scanning.

Changed

• Clarified acceptable use of StrichSDK.setCustomId(), personally identifying data must not be sent.

1.0.6 - 2023-04-19

Fixed

• The combination of Enterprise offline license with analytics opt-in did not work, no usage data was sent.

1.0.5 - 2023-04-18

Fixed

• Deactivating audio feedback (beep) was not possible.

Added

• Log a warning to the browser console if an invalid resolution (e.g. 'qhd') is specified in the frame source configuration.

1.0.4 - 2023-03-30

Fixed

• Internal code change that addresses a "ReferenceError: Must call super constructor in derived class before accessing 'this' or returning from derived constructor" build error in older optimized Angular versions.

1.0.3 - 2023-03-30

Changed

• Not setting a duplicateInterval in the engine configuration will now lead to a default 750ms interval to be used.

Fixed

• Ensured compatibility with iOS 16.4, do not attempt to instantiate a WebGL context on an OffscreenCanvas.

1.0.2 - 2023-03-23

Added

• Activated custom logo on overlay feature (Enterprise-only).

Fixed

• Added missing fallback to medium precision on devices which do not support WebGL high precision floats.

1.0.1 - 2023-03-20

Fixed

• Gracefully handle the situation where MediaStream does not implement getCapabilities() (e.g. Firefox Android).

• Avoid spurious exception after BarcodeReader.destroy() from an asynchronous overlay update in destroyed state

• Aztec code detection rectangle was not displayed on overlay for some non-compact Aztec codes.

1.0.0 - 2023-03-15

This is the first public release. A special thank you to all pilot users for getting us here!

Added

• Log engine version on initialization.

0.9.11 - 2023-03-13

Fixed

• Fixed memory access violations which manifested quickly when all symbologies are activated

0.9.10 - 2023-03-10

Changed

• Force WebGL context loss when destroying WebGL resources, avoiding warning messages when too many WebGL contexts are allocated.

Fixed

• BarcodeReader.destroy() did not destroy all engine resources, leading to intermittent crashes on iOS Safari

0.9.9 - 2023-03-10

Fixed

• BarcodeReader.destroy() now properly removes all elements added to the host element

• Respect analyticsOptOut: false for offline-capable licenses that still want usage data

0.9.8 - 2023-02-28

Fixed

• Fixed bug where online license verification was not retried on network errors, only on non-200 HTTP status codes.

0.9.7 - 2023-02-23

Fixed

• Fixed accidental inclusion of dependency.

0.9.6 - 2023-02-22

Fixed

• Fixed bug that prevented offline licenses from activating the SDK.

0.9.5 - 2023-02-22

Added

• Activated support for Offline licenses.

0.9.4 - 2023-02-21

Fixed

• Fixed a regression that caused problems reading rotated Aztec codes.

0.9.3 - 2023-02-14

Added

• Added this CHANGELOG.md file to the project.

0.9.2 - 2023-10-02

Changed

• Started using main instead of browser target in package.json to avoid problems with SSR frameworks such as Next.js.

0.9.1 - 2023-07-02

This is the first public release, distributed via NPMJS.
