0.1.3 (unreleased)

New:

project: NIAR_WORKING_DIRECTORY can be used to override the origin.
project: externals can be specified to pull in Verilog/RTLIL to build and Verilog to CXXRTL.
project: extension commands can be added.

Changed:

cxxrtl: don't show a Python backtrace when a build step fails.
cxxrtl: don't show a Python backtrace when interrupting the running program.
build/cxxrtl: show failing commands' exit statuses.

0.1.2

New:

build: platform_kwargs defined on the platform will be included in the platform.prepare() call.
build: timing information from place-and-route shown as part of post-build log.

Changed:

template: build CXXRTL with optimisations by default in CI (cf. amaranth-lang/amaranth-yosys#12).
XXX cxxrtl: disabled dependency tracking for now, as it's broken in the important case of source files which depend on the CXXRTL module itself (e.g. those which instantiate it!).

Fixed:

python: use PDM and declare dependencies correctly.
build: use generated IL to calculate digest, not what's on disk.
build: synthesis depends on the yosys script too, not just IL.
build: fix path used with cached synthesis when programming.

0.1.1

New:

setup-action: GitHub Actions support for preparing.
workflows: test in CI.
template: getting started template.

Changed:

python: move to src layout.
project: define root where pyproject.toml found.
cxxrtl: dependency tracking to avoid needless rebuilds.
cxxrtl: fix distinction between optimising RTL and code.
build: only resynthesise when RTLIL changes.
build: build subdirectory per platform.

Fixed:

cxxrtl: correctly disable when not used.
