Changed

[BREAKING] Make --script-mode default behavior; resolve tsconfig relative to entrypoint script instead of cwd (#949, #1197, #1155)
- In most cases this change will have no noticeable effect
- Primarily benefits portable shell scripts on your $PATH, because ts-node will respect the script's local tsconfig.json
- Use --cwd-mode or ts-node-cwd if you need legacy behavior
[BREAKING] ignore rules evaluate relative to tsconfig.json directory, otherwise cwd (#1155)
[BREAKING] Remove support for node 10. Minimum supported version is node 12 (#1312)
Rename --dir to --cwd; rename TS_NODE_DIR to TS_NODE_CWD (#1155)
- --dir and TS_NODE_DIR are deprecated but still parsed for backwards-compatibility
- --dir effectively changed the working directory of ts-node; renaming makes this behavior more obvious

Deprecated

Removed

[BREAKING] Internal APIs removed from type declarations (#1242)
- Removed DEFAULTS, normalizeSlashes, parse, split
- No features were removed
- This will only affect consumers of ts-node's programmatic API

Fixed

[BREAKING] Fix #1229 and #1235: always throw ERR_REQUIRE_ESM when attempting to execute ESM as CJS, even when not using --loader ts-node/esm (#1232)
- This aligns our behavior with vanilla node
[BREAKING] Fix #1225: compiler is loaded relative to tsconfig.json instead of entrypoint script (#1155)
- In most cases this change will have no noticable effect
Fix #1217: REPL not always using passed stdout and stderr (#1224)
Fix #1220: ts-node ./index may execute the wrong file extension because tsconfig search poisons the require.resolve cache (#1155)
Fix #1322: Sourcemaps fail for filenames with spaces or other characters which are percent-encoded in URLs (#1160, #1330)
Fix #1331: Resolution of node builtin modules in ESM loader fails on node >=12.20.0, <13 (#1332)
