V8 4.0.0 (2021-12-23)

If a call to ct$eval(),ct$get(), or ct$call() returns a JavaScript promise, you can set await = TRUE to wait for the promise to be resolved. It will then return the result of the promise, or an error in case the promise is rejected.
New section about promises in the intro vignette.
New function wasm_features() lists the supported WASM capabilities on the current installation.
Updated static libv8 for Mac and Linux to v8-v8-9.6.180.12
Windows ucrt: update libv8 to 9.1.269.38
Legacy libv8 versions (3.xx) are no longer supported. Package will still build but the examples and vignette now assume support for promises.
On Ubuntu, RHEL, and MacOS we now default to DOWNLOAD_STATIC_LIBV8=1 for supported architectures (amd64 and arm64). If this fails it will fall back on finding a local libv8. Opt-out by setting DISABLE_STATIC_LIBV8=1.

V8 3.6.0 (2021-11-10)

Try to give better error message when unable to allocate, probably due to hitting the stack limit. Previously we would see 'string conversion failed' which was very confusing.
The same stacklimit is now used across all platforms. Previously we would only set it on Linux, but apparently it is also needed on Windows sometimes.
Disable stacklimit when running in ASAN (which blows up the stack size)
Make DOWNLOAD_STATIC_LIBV8 the default on RHEL/CentOS based distros because these include a very old or no libv8.
Check and warn against very old libv8 when attaching the package.

V8 3.5.0 (2021-11-03)

On legacy systems which still have libv8 version 3.x we now try to download a more recent static libv8. We plan to deprecate support for libv8 3.x, which is now over 10 years old, and does not support ES6 (modern JavaScript).

V8 3.4.2 (2021-05-01)

Add Windows binaries for ucrt targets

V8 3.4.1 (2021-04-23)

Minor compatibility fixes by Jan Marvin for new versions of libv8.

V8 3.4.0 (2020-11-04)

When setting envvar DOWNLOAD_STATIC_LIBV8=1 on Linux at build-time, the configure script automatically downloads a static libv8, instead of looking for libv8 on the system. This allows the package to be installed on distros that do not have libv8, or ship with a very old V8.
The above should work for all x86_64 Linux systems with at least gcc-4.8.5 and is enabled by default on Travis and Github Actions.
Do not assume bash in configure script

V8 3.3.1 (2020-10-26)

Fix a bug in the configure script

Fix build for new V8 7.3.492.22 (Jan Marvin, #55)

V8 2.0 (2019-02-07)

Major upgrade: now support libv8 version 6.x and up. Note that this means we move to ES2015+ adding support for promises, async, etc. This may change the behavior of certain JavaScript libraries.
For now we also still stupport building with legacy V8 (3.14)
