Release 2.3.11 (1 Jan 2022) -- compared to 2.3.10

  • JPEG2000: enable multithreading for decoding (if using OpenJPEG >= 2.2)
    and encoding (if using OpenJPEG >= 2.4). This speeds up JPEG-2000 I/O
    by 3-4x. #2225
  • TIFF: automatically switch to "bigtiff" format for >4GB images. #3158
  • Security: New global OIIO attributes "limits:channels" (default: 1024) and
    "limits:imagesize_MB" (default: 32768, or 32 GB) are intended to reject
    input files that exceed these limits, on the assumption that they are either
    corrupt or maliciously constructed, and would, if read, lead to absurd
    allocations, crashes, or other mayhem. Apps may lower or raise these limits
    if they know that a legitimate input image exceeds these limits. Currently,
    only the TIFF reader checks these limits, but others will be modified to
    honor the limits over time. #3230
  • TextureSystem: enhance safety/correctness for untiled images that exceed
    2GB size (there was an integer overflow problem in computing offsets within
    tiles). #3232
  • Cleanup: Get rid of an obsolete header c-imageio.h that was experimental
    and the functions declared therein were not implemented in this release.
    #3237
  • Build: rely on env variable "OpenImageIO_CI" to tell us if we are running in
    a CI environment, not the more generic "CI" which could be set for other
    reasons in some environments. #3211
  • Build: Improvements in how we find OpenVDB. #3216
  • Build: If CMake variable BUILD_TESTING is OFF, don't do any automatic
    downloading of missing test data. #3227
  • Dev: Add Strutil::edit_distance(). #3229
  • Docs: Clean up intra-document section references, new explanations about
    input and output configuration hints, more code examples in both C++ and
    Python (especially for the ImageInput and ImageOutput chapters). #3238 #3244
