v1.11.1

Fixed

• python: get_language() and other download failures now surface the public exception type in tracebacks — tree_sitter_language_pack.DownloadError instead of _native.DownloadError (#147).
• java: generate ByteArraySerializer.java so the generated ObjectMapper compiles for every package.
• docs: correct stale "300+" language counts to "306".
