We have tagged v2.3.19.0 as the latest production release and moved the
"release" branch marker to that point. This is guaranteed to be API, ABI, and
link back-compatible with prior 2.3 releases.
This is likely to be the last "current" 2.3 release, as the beta for 2.4 is
imminent, and 2.4 will almost certainly become the release family before
September is over. After that, the 2.3 branch will be considered the "obsolete"
branch and will get progressively more infrequent and smaller updates. You
should expect that from here on out, only important bug fixes, and no new
features, will be put into 2.3.
Release 2.3.19 (1 Sep 2022) -- compared to 2.3.18
---------------------------------------------------
* idiff: `--allowfailures` allows the specified number of pixels to differ by
any amount, and still consider the images to compare successfully. #3455
* idiff: `--failrelative` and `--warnrelative` allows the failure and warning
threshold to use a symmetric mean relative error (rather than the absolute
error implied by the existing `--fail` and `--warn` arguments). #3508
* A new flavor of `ImageBufAlgo::compare()` allows relative as well as
absolute error thresholds. #3508
* Build: Fixes for ffmpeg 5.1 detection. #3516
* Build: suppress incorrect warnings for gcc 12. #3524
* CI: New test on MacOS 12, remove test on MacOS 10.15 (GitHub Actions is
imminently removing MacOS 10.15). #3528
* oiiotool, maketx, iinfo, igrep, and iv now all take a `--version` command
line argument, which just prints the OIIO version and exits. #3534
* `OIIO::getattribute("version")` now retrieves the version string. #3534
* Developer goodies: `ArgParse::add_version(str)` tells ArgParse the version
string, which will automatically add an option `--version`. #3534
