0.13.13

0.13.13 has 127 commits from 5 contributors. Selected changes:

Fixes:

• Correctly resolve wildcards on this and carry column aliases through natural joins, by fixing how the compiler's internal tuple_map applies redirects, folds expressions, and propagates aliases. (@kgutwin, #5875, #5877, #5980)
• Resolve identifiers up the parent module chain. (@prql-bot, #5976)
• Return a compiler error instead of panicking in lookup_cid. (@prql-bot, #5938)
• Catch a panic in the CLI's compile path so the debug log is still written. (@kgutwin, #5869)
• Set the minimum chrono version to 0.4.40 for compatibility with arrow-arith. (@prql-bot, #5841)

Documentation:

• Numerous typo, grammar, and stale-content fixes across the book, tutorials, bindings docs, and code comments.

Integrations:

• Fix several FFI defects in the .NET binding that prevented it from working correctly on 64-bit platforms or returning more than one diagnostic: map size_t as UIntPtr (was int), advance the pointer when iterating the messages array, dereference indirect string fields and Span / Location pointers, call result_destroy to free native memory, and tighten exception types and doc references. Also guard result_destroy in prqlc-c against a null messages pointer, which is set on the success path. (@prql-bot, #5848)
• Modernize the .NET binding to net10.0 using LibraryImport source generators. (@prql-bot, #5850)
• Throw a Java exception instead of panicking in the JNI bindings. (@prql-bot, #5934)
• Exit the LSP server only on the exit notification, matching the LSP spec. (@prql-bot, #6001)

Internal changes:

• Update the tend (Claude-powered CI) workflows; most of this release's bot-authored fixes were filed by tend.
• Scope release secrets to a protected GitHub environment. (@max-sixty, #5910)
• Replace the internal tuple_every helper with a more general tuple_reduce. (@kgutwin, #5878)
• Update the Rust toolchain version. (#5966)

0.13.12

0.13.12 has 81 commits from 10 contributors. Selected changes:

Language:

• Remove the deprecated std.prql_version function. Use prql.version instead, which has been the supported replacement since 0.11.1. (@prql-bot, #5806)

Features:

• Add a very early sql.oracle dialect. It currently only forces identifier quoting to accommodate Oracle's case-folding rules; most other features fall back to generic SQL. (@julien-pinchelimouroux, #5821)
• Add date.trunc function for date truncation. (@happyso, #5729)
• Add date.now function for current timestamp. (@happyso, #5721)
• Add date.diff function for date differences. (@happyso, #5726)
• Add DuckDB target to the Elixir bindings. (@prql-bot, #5817)

Fixes:

• Loosen the chrono constraint from 0.4.44 to 0.4 to avoid version conflicts with downstream crates such as polars. (@lukapeschke, #5834)
• Correct the SQLite div_i formula so integer division returns the right result when |dividend| < |divisor| (e.g., 1 // 2 now returns 0 instead of -1). (@queelius, #5736)
• Return an error rather than emitting invalid SQL when date.trunc is used against SQLite. (@prql-bot, #5733)
• Sync :duckdb into the Elixir PRQL.Native.CompileOptions target typespec so target: :duckdb actually reaches the DuckDB dialect. (@prql-bot, #5823)
• Correct the Vec::from_raw_parts element type in prqlc-c to fix undefined behavior in result_destroy. (@prql-bot, #5732)
• Prevent panic in prqlc-macros by correcting a stale macro name in the panic message. (@prql-bot, #5811)
• Align Emacs grammar keywords and regex with the lexer. (@prql-bot, #5795)
• Correct the playground's decimal regex and transforms list in syntax highlighting. (@prql-bot, #5788)
• Correct the aarch64 target path in the Java cross-compilation script. (@prql-bot, #5781)

Documentation:

• Numerous typo, grammar, and stale-content fixes across the book, tutorials, bindings docs, and code comments.

Integrations:

• Kakoune 2026.04.12 has syntax highlighting for PRQL. (@vanillajonathan)

Internal changes:

• Add tend (Claude-powered CI) workflows for autonomous PR review, issue triage, CI-failure fixes, and a nightly code-quality sweep. Most of this release's bot-authored fixes were filed by tend. (#5727)
• Update the Rust toolchain version. (#5807)
• Switch from mypy to ty for Python type checking. (#5761)
