+# Changelog
+
+All notable changes to this project will be documented in this file.
+
+The format is loosely based on [Keep a Changelog](https://keepachangelog.com).
+
+--------------------------------------------------------------------------------
+
+## [Unreleased] - 2024-10-06
+
+### Changed
+
+- Updated cudacpp version to 1.00.01.
+
+### Fixed
+
+- Platform-specific issues
+  - AV ([#1011]) Added workaround for Floating Point Exceptions in vxxxxx in the HIP backend.
+
+- Infrastructure issues
+  - AV ([#1013]) Fix release scripts to create 'v1.00.01' tags from a '(1,0,1)' python tuple.
+  - AV ([#1015]) Remove add_input_for_banner from output.py (plugin_run_card is not needed in cudacpp).
+  - AV ([#995]) In cudacpp_config.mk move default FPTYPE from 'd' to 'm' (already the default floating_type in run_card.dat).
+
+--------------------------------------------------------------------------------
+
+## [1.00.00] - 2024-10-03
+
+### Added
+
+- (OM+AV+SR+SH+ZW+JT+DM) First release of the MG5aMC CUDACPP plugin.
+  - Validated and released for MG5aMC version 3.6.0.
+  - Hosted in the https://github.com/madgraph5/madgraph4gpu original repo.
+  - Repo uses the original directory structure (plugin is epochX/cudacpp/CODEGEN/PLUGIN/CUDACPP_SA_OUTPUT).
+
+### Known issues
+
+- This section lists some of the main new issues identified in release v1.00.00.
+
+- General issues
+  - ([#959]) Cross-section instabilities when changing vector size between 32 and 16384.
+  - ([#993]) LHE file mismatch (fortran vs cudacpp) in the experimental multi-backend gridpacks.
+
+- Platform-specific issues
+  - ([#1011]) Floating Point Exceptions in vxxxxx in the HIP backend.
+
+- Physics-process-specific issues
+  - ([#944]) Cross-section mismatch (fortran vs cudacpp) in Drell-Yan plus 4 jets.
+  - ([#942]) Floating Point Exceptions in Drell-Yan plus 0 to 2 jets (workaround: `CUDACPP_RUNTIME_DISABLEFPE=1`).
+  - ([#846]) ME mismatch (HRDCOD=1 vs HRDCOD=1) in EWdim6 models.
+  - ([#601]) Builds fail with very complex final states (e.g. gg to ttgggg).
