This Opus 1.2.1 minor release fixes a relatively rare issue where the 1.2 encoder would wrongly assume a signal to be bandlimited to 12 kHz and not encode frequencies between 12 and 20 kHz.
This only happens on a few clips, but it is good to update to avoid a potential loss of quality.
There are no other changes compared to 1.2.
Issues addressed:
- xcode build failed with
... was built for newer OSX version (10.10) than being linked (10.5)
fixed by setting GYP mac deployment target to the nix value
- a gyp bug when SDKROOT is not set (and removed an orphaned gyp patch
- path to python in generated gyp-mac-tool
- noisy build due to static assert warnings, by silencing warnings
- use of system xcodebuild and libtool replaced by darwin.cctools
Qt 5.8 is immediately removed because its support window is ended.
The qtlocation module is built with `enableParallelBuilding = false` so that the
clipper library will be built before the components which link to it.
kjs now depends directly on pcre. The dependency was previously propagated from
qtbase, which now depends on pcre2.
The setup hooks for many kdeFrameworks and plasma5 packages were erroneously
running before $outputDev was set. This lead to .dev outputs being propagated
into the user environment.
Packages get --host and --target by default, but can explicitly request
any subset to be passed as needed. See docs for more info.

Changes since 1.1.x include:
- Speech quality improvements especially in the 12-20 kbit/s range
- Improved VBR encoding for hybrid mode
- More aggressive use of wider speech bandwidth, including fullband speech starting at 14 kbit/s
- Music quality improvements in the 32-48 kb/s range
- Generic and SSE CELT optimizations
- Support for directly encoding packets up to 120 ms
- DTX support for CELT mode
- SILK CBR improvements
- Support for all of the fixes in draft-ietf-codec-opus-update-06 (the mono downmix and the folding fixes need --enable-update-draft)
- Many bug fixes, including integer wrap-arounds discovered through fuzzing (no security implications)
