Four separate 0.15 changes, all fixable with spellings that both
versions accept, so this widens support rather than cutting over.
Build system:
- addStaticLibrary/addSharedLibrary fold into addLibrary with an
explicit .linkage, and target/optimize move onto a module passed as
.root_module.
Calling convention (52 sites in src/vst3.zig and the gain example):
- callconv(.C) -> callconv(.c). The CallingConvention union was
reworked; 0.14.1 already accepted the lowercase form.
std.Io rework:
- net.Stream.readAll was removed. Replaced with a single read, which
is the correct semantic here anyway: readAll blocks until the 8 KB
buffer fills or the peer closes, so a keep-alive HTTP client would
hang.
ArrayList:
- 0.15 made ArrayList unmanaged by default and dropped
.init(allocator). ArrayListUnmanaged names the same type in both, so
the allocator is passed per call instead.
The webview dependency also had to move: its pinned commit used the
removed build API. Bumped to a5eef0b, which uses the new one. That in
turn renamed WindowSizeHint.Fixed to .fixed.
Verified on both toolchains from a clean cache:
0.14.1 24/24 build steps, 35/35 tests
0.15.2 24/24 build steps, 35/35 tests, vst3 bundle still fat
(x86_64 arm64)
CI runs a matrix over both. Also corrects two stale README claims: the
Zig version requirement, and a License section pointing at a project
root that no longer holds the license.
