Languages — Coverage Roadmap

Coverage Roadmap

What’s covered, what’s deferred. Updated as tiers complete.

Decision log

• 2026-05-06 — User selected Tier 1 (Top ~25) with web-first sourcing + citations. Tiers 2 and 3 deferred; structure below makes them easy to pick back up.

Tier 1 — Top 25 (in progress / completed)

Source basis: TIOBE 2026 + Stack Overflow Developer Survey 2025 + GitHub Octoverse 2025.

21	R	pending
22	Julia	pending
23	Zig	pending
24	Nim	pending
25	Crystal	pending
26	OCaml	pending

Tier 2 — Deferred (next batch)

When approved, add: Perl, Erlang, Racket, Common Lisp, Scheme, Fortran, COBOL, Ada, Pascal, Prolog, Tcl, Groovy, Bash, PowerShell, SQL dialects, V, Odin, Roc, Gleam, Pony, Idris, Lean, Coq, Agda, Smalltalk.

Estimated effort: similar pattern (parallel agent fetch + write), another session.

Tier 3 — Deferred (encyclopedic)

When approved, add an index of 200+ languages with one-line summary + link to syntax sample. This is more of a discovery aid than a learning resource.

Source basis: GitHub language stats, Wikipedia list of programming languages.

Cross-cutting notes (deferred — useful add-ons)

• Memory models comparison (GC vs RC vs ownership vs manual)
• Type system spectrum (dynamic ↔ gradual ↔ static ↔ dependent)
• Concurrency model spectrum (threads / actors / CSP / async / STM)
• Build/package manager comparison
• Macro / metaprogramming comparison
• “If you know X, learn Y next” graph

Maintenance

• Re-fetch official docs & update latest_version per note every ~6 months.
• When a language note is read by an agent and the agent finds it stale, log via obsidian-research log with the language name + what was wrong, so the next maintenance pass catches it.

Update — 2026-05-06T23:55:29.174Z (claude-code)

Tier 1 — COMPLETE (2026-05-06)

All 26 notes written and indexed. Verified via obsidian-research.mjs list --path Languages.

26	OCaml	ocaml.md	OCaml 5.4.1; multicore + effects

Caveats from this batch (worth re-verifying on next maintenance pass)

• PHP 8.5 — agent noted the official php.net page returned a release date matching today’s date (2026-05-06), looked like model-echo. Note records release as ~2025-11 (normal November cadence). Verify on the next pass via php.net/downloads.php.
• Ruby 4.0.3 — release date not on the downloads page; date field left blank.
• C++ — cppreference 403 — WebFetch was blocked by cppreference.com; agent fell back to isocpp.org/std/status + Wikipedia for version/feature claims. cppreference is still cited as the canonical reference URL.

What’s next (when approved)

• Tier 2 (~25 more): Perl, Erlang, Racket, Common Lisp, Scheme, Fortran, COBOL, Ada, Pascal, Prolog, Tcl, Groovy, Bash, PowerShell, SQL dialects, V, Odin, Roc, Gleam, Pony, Idris, Lean, Coq, Agda, Smalltalk.
• Tier 3 (encyclopedic, 200+): one-line + link per language, sourced from GitHub language stats + Wikipedia list of programming languages.
• Cross-cutting notes: memory models, type system spectrum, concurrency model spectrum, build/package manager comparison, macro/metaprogramming comparison, “if you know X, learn Y next” graph.

To resume Tier 2, the same parallel-agent pattern works: 5 agents x 5 languages each. Total wall-clock ~15-20 min based on this batch.

Update — 2026-05-07T00:21:01.329Z (claude-code)

51	Smalltalk	smalltalk.md	Pharo 13.x (2025); image-based live programming; becomeForward:; Iceberg git; Bloc/Roassal

Caveats from this batch (worth re-verifying on next maintenance pass)

• Coq → Rocq rename — corrected 2026-05-07: announcement was 2023-10-11; official rename completed with Rocq 9.0.0 release on 2025-03-12. Slug stays coq for canonical addressing; title is “Coq (Rocq) — Reference”; rename callout updated in coq.
• Roc has TWO compilers in parallel (Rust LLVM-backed alpha4 + Zig rewrite with diverging syntax) — note describes both architectures.
• Tcl 9 — meaningful breaking changes vs 8.x (unqualified namespace var lookup, no tilde expansion, fatal I/O encoding errors). Worth a heads-up for any agent porting Tcl 8 scripts.
• Bash 5.3 — ${ command; } value-substitution (captures stdout WITHOUT forking) is genuinely new and worth knowing.
• SQL:2023 — added JSON data type to Foundation + Part 16 (SQL/PGQ Property Graph Queries) — recent enough that few dialects implement it yet.

What’s left (still deferred)

• Tier 3 (encyclopedic 200+): one-line + link per language, sourced from GitHub stats + Wikipedia list of programming languages. Fundamentally an index, not a learning resource.
• Cross-cutting notes: memory models comparison, type system spectrum (dynamic ↔ gradual ↔ static ↔ dependent), concurrency model spectrum (threads / actors / CSP / async / STM), build/package manager comparison, macro/metaprogramming comparison, “if you know X, learn Y next” graph.

To resume Tier 3: pattern likely changes — Tier 3 is best built as a single big list note + a small batch of agents doing 40 langs each (one-paragraph each). Cross-cutting notes are best done by a single focused agent that has access to all 51 existing notes for cross-referencing.

Update — 2026-05-07T11:30:04.953Z (claude-code)

Cross-cutting notes — COMPLETE (2026-05-07)

All 6 cross-cutting comparison notes written and indexed. Library structure now:

• 51 per-language notes (Tier 1 + Tier 2)
• 6 cross-cutting comparison notes (the SYNTHESIS layer)
• 3 framework files (_index, _schema, _roadmap)
• Total: 60 files in Languages/

Cross-cutting note	Topic
_compare_memory_models.md	Memory models comparison (manual / RAII / ownership / refcaps / RC / GC / image-based)
_compare_type_systems.md	Type system spectrum (dynamic → gradual → static → dependent + variance, linearity, set-theoretic)
_compare_concurrency.md	Concurrency model spectrum (threads / actors / CSP / async / STM / coroutines / data-parallel)
_compare_metaprogramming.md	Macros / decorators / codegen / reflection / type-level computation comparison
_compare_build_tools.md	Package managers + build tools per language; what good tooling looks like
_learn_next.md	Directed recommendation graph: “if you know X, learn Y to gain Z” for each of 51 langs

Build process notes

• First attempt used 3 parallel sub-agents; all 3 hit ECONNRESET API errors mid-task. Zero saves before failure.
• Recovery: wrote all 6 inline in the main session via temp-file pattern. Robust, complete, took longer.

What’s left (still deferred)

• Tier 3 (encyclopedic 200+ language index): one-line + link per language, sourced from GitHub stats + Wikipedia list of programming languages. Different shape from Tier 1/2 — fundamentally an index, not a learning resource. Best decomposed into language families (10-15 notes covering 200+ langs in a tabular format) rather than 1 note per language.

To launch Tier 3, the structure question is whether to use:

1. One big _tier3_index.md note with all 200+ in tables grouped by family.
2. One folder Languages/Tier3/ with ~10-15 family-grouped notes (Lisps, MLs, BASICs, esoteric, mainframe, hardware, etc.).
3. Per-language slug (200+ tiny notes), same as Tier 1/2 but much less depth each.

Recommendation: option 2 — folder of family-grouped notes. Easier to query, easier to extend, doesn’t bloat the top-level Languages/ folder.

Update — 2026-05-07T12:09:57.535Z (claude-code)

Tier 3 — COMPLETE (2026-05-07)

13 family-grouped index notes saved in Languages/Tier3/. ~310 languages catalogued across the family tables (not counting the 51 already in deep notes).

Library now totals 74 files and 588 indexed chunks:

• 3 framework files (_index, _schema, _roadmap)
• 51 deep per-language notes (Tier 1 + Tier 2)
• 6 cross-cutting comparison notes
• 14 Tier 3 files (family _index + 13 family notes)

Tier 3 family note inventory

File	Family	Approx count
Tier3/lisps.md	Lisp dialects beyond CL/Scheme/Racket/Clojure	~30
Tier3/ml-and-fp.md	ML family + extended FP beyond Haskell/OCaml/F#/Roc/Gleam	~22
Tier3/basics-and-teaching.md	BASIC + Smalltalk variants + teaching/visual	~44
Tier3/mainframe-legacy.md	PL/I, RPG, REXX, ABAP, Progress 4GL, etc.	~24
Tier3/hdl.md	Verilog, VHDL, Chisel, Amaranth, etc.	~17
Tier3/gpu-and-shaders.md	CUDA, GLSL, WGSL, Triton, Mojo, etc.	~18
Tier3/scientific.md	MATLAB, Mathematica, APL, Stan, Modelica, etc.	~27
Tier3/config-and-dsl.md	Nix, Dhall, HCL, Starlark, build DSLs	~25
Tier3/query.md	Datalog, Cypher, GraphQL, KQL, JQ, etc.	~22
Tier3/esoteric.md	Brainfuck, Befunge, code-golf langs	~22
Tier3/forth-and-concatenative.md	Forth, PostScript, Joy, Factor	~18
Tier3/logic-and-constraint.md	Datalog, miniKanren, Mercury, ASP family	~17
Tier3/experimental-and-cross-host.md	Carbon, Mojo, blockchain langs, transpiled-to-JS	~28

Build process

• 5 parallel sub-agents launched, each handling 2-3 family notes
• All 5 succeeded on first attempt (unlike the cross-cutting batch where all 3 hit ECONNRESET)
• Total wall-clock: ~5 minutes for the parallel agents + 1 minute for the index file

Coverage gaps and intentional omissions

Documented in _index. Highlights:

• Markup-only formats (HTML/JSON/YAML standalone) — not languages.
• Per-game scripting (UnrealScript, Wren, Pawn) — could be a future family note.
• Embedded/firmware (TinyGo, MicroPython) — could be a future family note.
• Spreadsheet languages (Excel LAMBDA, M, DAX) — could be a future family note.

Library complete

The original ask “find every current programming language … categorize and store in vault” is fully addressed:

• ~360 languages catalogued (51 deep + ~310 indexed in family notes)
• 74 files in the vault
• 588 chunks indexed for semantic search
• All accessible to any agent on this machine via obsidian-research.mjs query / read / list

Future maintenance

• Re-fetch official docs and update latest_version per deep note every ~6 months
• When agents discover stale info, log via obsidian-research log with the language name + what was wrong
• Optional next family notes documented in _index under “Suggested next family notes”

Update — 2026-05-07 (expansion pass — 7 new family notes + maintenance)

Original library was 74 files; expansion added 7 family-index notes and 4 maintenance fixes. Library now 81 files, 20 family indexes, ~440 catalogued languages (51 deep + ~390 in family notes — was ~310).

New family notes added

#	Family	File	Approx count
14	Game scripting	Tier3/game-scripting.md	~15
15	Embedded / firmware	Tier3/embedded-firmware.md	~17
16	Spreadsheet languages	Tier3/spreadsheet.md	~18
17	AI / agent / prompt languages	Tier3/ai-prompt-languages.md	~18
18	Notation / specification / verification	Tier3/notation-spec.md	~19
19	Music / audio synthesis	Tier3/music-audio.md	~18
20	Visual / dataflow	Tier3/visual-dataflow.md	~22

Maintenance fixes applied

• PHP 8.5 — release date pinned to 2025-11-20 (was “2025-11” with caveat) — verified via https://www.php.net/releases/8.5/en.php.
• Ruby 4.0.3 — confirmed correct (released 2026-04-21 — note matches reality, no edit needed).
• Coq → Rocq rename — corrected dates: announced 2023-10-11, finalized with Rocq 9.0.0 on 2025-03-12 (was “2025-05-14” — that URL/date appears to have been hallucinated).
• Tcl 9.0 breaking changes — confirmed deep note already covers all four items in Gotchas (unqualified namespace var lookup, tilde expansion, fatal I/O encoding errors, tcl_precision deprecation). No fix needed.

Build process

• 7 parallel sub-agents launched in background, all completed successfully on first attempt (no ECONNRESET this time)
• Maintenance fixes done inline via Edit tool while agents ran
• Total wall-clock: ~4 minutes parallel + ~1 minute index updates

Verification

After saves:

• obsidian-research.mjs index re-run for semantic search
• Test queries against new family notes confirmed they’re discoverable via --hybrid search

What’s left after this pass

Library is again “complete” in the sense that the original ask is satisfied. Future-only items:

• Robotics/control DSLs family note (RDL, KRL, ROS launch)
• Document/typesetting family note (TeX, LaTeX, Typst, Pollen)
• Smart-contract DSL specialization (could split from experimental-and-cross-host)
• Six-month version refresh on all 51 deep notes (still scheduled for ~2026-11)

Update — 2026-05-09 (fourth Tier 3 expansion pass)

Added 4 more family-index notes: theorem-prover-dsls, regex-flavors, math-notation, game-engine-scripting. Library now 93 files, 32 family indexes, ~745 catalogued languages (51 deep + ~694 in family notes — was ~640).

New family notes added

#	Family	File	Approx count
29	Theorem-prover DSLs (Ltac/Ltac2, Lean macros, Isar, Mizar, MetaCoq, CoqHammer, Sledgehammer)	Tier3/theorem-prover-dsls.md	~27
30	Regex flavors (PCRE2, RE2, .NET, Java, JS /v, Python, POSIX BRE/ERE, Vim, Hyperscan)	Tier3/regex-flavors.md	~22
31	Mathematical / proof notation (TeX/LaTeX, MathML, AsciiMath, Wolfram, Typst, OpenMath, TikZ)	Tier3/math-notation.md	~26
32	Game-engine scripting & level description (Quake .map, Source FGD/VMF, Unity prefabs, Unreal Blueprint, USD)	Tier3/game-engine-scripting.md	~30

Notable findings flagged this pass

• Coq → Rocq rename now fully complete: Rocq Prover 9.0 shipped 2025-03-12, Ltac2 promoted into rocq-core. Deep note already current.
• Lean 4 grind tactic (v4.25, 2025-11-14) added interactive grind => ... mode and show_splits / finish? / non-commutative semiring support — biggest mathlib4-adjacent tactic of late 2025.
• JS /v flag confirmed: ES2024, V8 11.2 / Chrome 112 / Safari 17 / Node 20 — set notation regex.
• .NET 7’s RegexOptions.NonBacktracking (MSR derivative-based) and [GeneratedRegex] source-generator are RE2-class guarantees in .NET — recent enough that few codebases use it yet.
• Counter-Strike 2 ships THREE scripting systems (cs_script JS, VScript2 TS, Pulse visual) — Pulse is Valve’s first first-party visual-scripting solution.
• Blueprint → UnrealScript-VM bytecode: the literal UE3 UnrealScript VM lives on inside UE5/5.6 powering Blueprint via FKismetCompilerVMBackend. The “nativise to C++” experiment was deprecated in UE5.
• Verse is the planned UE6 unification language per Tim Sweeney; targeted 2027–2028. UE 5.7 (2026) is the last UE5-line release.
• Oniguruma archived April 2025; Onigmo (the Ruby fork) continues as the canonical engine for Ruby regex.
• TeXmacs 2.1.5 (2026-03-17) is the current mathematical-WYSIWYG editor with Qt6 default.
• Wolfram Language v14.3 launched 2025-08; the InputForm/StandardForm/FullForm three-form architecture is the cleanest separation of parsing/display/term-tree of any system surveyed.

Build process

• 4 parallel sub-agents launched in background, all completed successfully on first attempt
• Total wall-clock: ~7 minutes parallel + ~1 minute index updates
• No ECONNRESETs this round

What’s left after this pass

The library is now extremely deep in coverage. Tier 3 _index updated to reflect 32 families. Remaining suggested gaps (smaller, more niche):

• Hardware low-level encoding (x86/ARM/RISC-V assembly dialects, GAS/MASM/NASM/FASM, ELF/PE/Mach-O notation)
• Constraint / SMT input formats (DIMACS CNF, SMT-LIB 2.6, MiniZinc, ASPCore-2)
• Educational pseudo-code dialects (CIE/AQA/IB CS exam pseudocode)
• Codec / signal-processing DSLs (SOUL, Cmajor, FFmpeg filter graphs)
• Six-month deep-note version refresh still scheduled for ~2026-11

Update — 2026-05-09 (fifth Tier 3 expansion pass — assembly)

Added the assembly-and-encoding family-index note. Library now 94 files, 33 family indexes, ~780 catalogued languages (51 deep + ~729 in family notes — was ~745).

New family note

#	Family	File	Approx count
33	Assembly & low-level encoding (17 ISA dialects + 8 assemblers + 10 binary/debug formats)	Tier3/assembly-and-encoding.md	~35

Notable findings flagged this pass

• RISC-V RVA23 profile ratified 2024-10-21 — vector + hypervisor now mandatory. Source: riscv.org.
• WebAssembly 3.0 released 2025-09 with GC, exnref exception handling, Memory64, and tail calls.
• NASM 3.00 (2025-10) — first major assembler with full Intel APX + AVX10 support; the long-stable 2.x series finally bumped. Anyone using NASM should know about the 3.x boundary.
• Intel APX spec at v8 (2025-07); kernel patches still landing H2 2025; first silicon not in next-gen but next-next-gen.
• DWARF 6 still working draft; latest snapshot 2025-05-05; DWARF 5 (2017) remains production-canonical.
• IBM z17 GA 2025-06-18 with Telum II.
• ARMv9.6-A announced 2024-10 with SME structured-sparsity improvements.
• Zilog officially EOL’d the Z80 in April 2024 with last orders mid-2024 — the 8-bit retro/educational dialect is now post-silicon.
• MIPS post-bankruptcy (2021-03) is now a Tallwood VC entity that has pivoted to RISC-V cores.
• DWARF expressions are formally Turing-complete — DW_OP_* includes branches and arithmetic, so .debug_loc sections contain compiled DWARF programs. Worth a deeper deep-dive someday.
• eBPF Foundation funded $100k in formal-verification grants in 2025 — unusual organisational backing for a kernel feature.

Build process

• Single sub-agent in background, completed first try
• Wall-clock: ~5 minutes for the agent + ~1 minute for index/roadmap updates
• 7 caveats flagged at bottom of the note for unverifiable items (MASM version stream, FASM 2 vs FASMg, DWARF 6 ratification, PE/COFF spec versioning, Intel HEX canonical URL, MIPS 2026 status, “is eBPF really assembly”)

What’s left after this pass

• Constraint / SMT input formats (DIMACS CNF, SMT-LIB 2.6, MiniZinc, FlatZinc, ASPCore-2)
• Educational pseudo-code dialects (CIE/AQA/IB CS exam pseudocode)
• Codec / signal-processing DSLs (SOUL, Cmajor, FFmpeg filter graphs)
• Optional split-out of DWARF expressions as a Turing-complete sub-DSL
• Six-month deep-note version refresh still scheduled for ~2026-11

Update — 2026-05-09 (sixth Tier 3 expansion pass — final niche batch)

Added 4 more family-index notes: constraint-and-smt-input, exam-pseudocode, codec-and-dsp, dwarf-expressions. Library now 98 files, 37 family indexes, ~872 catalogued languages (51 deep + ~821 in family notes — was ~780).

New family notes added

#	Family	File	Approx count
34	Constraint / SMT / SAT input languages	Tier3/constraint-and-smt-input.md	~40
35	Educational exam pseudocode	Tier3/exam-pseudocode.md	~19
36	Codec / DSP / signal-processing	Tier3/codec-and-dsp.md	~17
37	DWARF expressions & debug-info sub-DSLs	Tier3/dwarf-expressions.md	~16

Notable findings flagged this pass

• SMT-LIB roadmap: 2.6 (current, latest revision 2021-05-12), 2.7 draft (2025-02-05), 3.0 in design — bigger refresh wave coming.
• MiniZinc 2.9.7 (2026-04-30 release) is current.
• DRAT/LRAT/FRAT chain emerged after the 2016 “Schur five-coloring” SAT proof had a 200TB resolution proof that nobody could check by eye — formal proof-format trust crisis is a real story.
• CP-SAT’s cp_model.proto is the first protobuf-native solver input format in widespread use.
• AP CSA went fully digital in May 2025 (Bluebook sandbox) — students now type-and-run real Java in the exam itself, dissolving the pseudocode/code distinction for AP CSA.
• CIE 9618 (2026 cycle) doubled down on strict Pascal-flavoured pseudocode against the Python-takeover trend — fresh 2026 Teachers’ Guide PDF (697401-2026).
• AP CSP, IB CS Diploma, NCEA are quietly letting Python become the answer language alongside pseudocode.
• CLRS pseudocode is arguably the most-read pseudocode dialect on Earth despite never appearing on an exam — every CS grad student internalises it.
• Knuth TAOCP “pseudocode” is fundamentally different (numbered-step English prose paired with MIX/MMIX assembly listings) from CLRS — they’re stylistically nothing alike yet both called “textbook pseudocode.”
• FFmpeg 8.1.1 (2026-05-04) is current; FFmpeg filter-graph syntax has more lines deployed in production than any music DSL by orders of magnitude despite no formal language identity outside libavfilter/graphparser.c.
• VST3 SDK is now MIT-licensed (GPLv3 + Steinberg-proprietary withdrawn) — a meaningful licensing pivot for plugin developers.
• SOUL (ROLI) deprecated 2022 after ROLI’s collapse; Cmajor (SoundStacks, Storer + Ferrari) is the named spiritual successor — split between SoundStacks/cmajor and cmajor-lang/cmajor GitHub orgs; cmajor.dev is canonical.
• DWARF 6 working draft snapshot 2025-05-05 confirmed at sourceware.org. libdwarf 2.3.1 released 2026-03-04. GCC has begun emitting DW_AT_language_name / DW_AT_language_version for DWARF 6.
• Turing-completeness of DWARF expressions is precise: DW_OP_bra + DW_OP_skip give bounded loops; full Turing-completeness requires DW_OP_call_ref (cross-CU recursion).
• CodeView and Mach-O __compact_unwind are both officially undocumented — LLVM and community reverse-engineering serve as de-facto specs.
• WebAssembly DWARF and AMDGPU heterogeneous DWARF extend the family beyond CPU/OS combinations.

What’s left after this pass

The Tier 3 library is now extremely comprehensive at 37 families / ~872 languages. Remaining suggested gaps are deep-niche (chatbot intent DSLs, bibliographic citation formats, crystallography/biology file-format languages, GPS/geo-spatial DSLs). Six-month deep-note version refresh still scheduled for ~2026-11.

Update — 2026-05-10 (seventh Tier 3 expansion pass — deep-niche batch)

Added 4 more family-index notes: chatbot-intent-dsls, citation-formats, bio-fileformats, geospatial. Library now 102 files, 41 family indexes, ~977 catalogued languages (51 deep + ~926 in family notes — was ~872).

Notable findings flagged this pass

Chatbot intent / NLU:

• 4 parallel sub-agents in background, all completed first try.
• Wall-clock: ~5 minutes parallel + ~1 minute index/roadmap + cross-link fixes.
• No ECONNRESETs.

What’s left after this pass

Notable findings flagged this pass

Government / civic-tech:

• CSAF 2.0 became ISO/IEC 20153 in May 2025 — procurement-tipping moment.
• CycloneDX 1.6 is now an ECMA standard (ECMA-424), parallel to SPDX’s ISO status.
• MITRE ATT&CK v19 (April 2026) — split Defense Evasion into Stealth + Defense Impairment.
• SPDX 3.0.1 (Aug 2025); MISP v2.5.37 (May 2026); DCAT-AP 3.0.1 aligned with W3C DCAT 3 Recommendation (Aug 2024).
• NIEMOpen transitioned to OASIS, community-run since Oct 2025; v6.0 in progress.

Cryptography / keys:

• OpenPGP RFC 9580 (July 2024) obsoletes 4880/5581/6637. LibrePGP fork (still active) is the first real OpenPGP split since 1998 — GnuPG 2.4.x is NOT tracking RFC 9580; interop between RFC-9580 keyrings and GnuPG can fail silently.
• OASIS KMIP 3.0 CSD01 (Aug 2024); public review Sept 2024.
• OASIS PKCS#11 v3.2 (Nov 2025), succeeding v3.1 (July 2023).
• SOPS v3.12.2 (Mar 2026, CNCF Sandbox since 2023); age v1.3.x current.
• Cosign v3.0 with bundles default-on (2025); TUF 6.0 (2025-03-11) with attestation bundles.

• HashiCorp Vault 1.20.x GA (June 2025), IBM-stewarded.
• RFC 9579 (May 2024) retired the legacy PKCS#12 v1 KDF in favour of PBKDF2/PBMAC1.
• DSSE (Dead Simple Signing Envelope) is the actual signature wrapper under in-toto/SLSA/Sigstore, replacing JWS for canonicalisation reasons.
• Sigstore keyless-signing adoption wave: Homebrew (May 2024) → PyPI (Nov 2024) → Maven Central (Jan 2025) → NVIDIA NGC (July 2025); Debian/RPM ecosystem still the gap.

Genealogy:

• GEDCOM 7.0.18 current; 7.0.16 (March 2025), 7.0.17 (Feb 2026); 7.1 working draft on GitHub.
• GEDCOM 5.5.1 still dominant despite GEDCOM 7 being out 5 years — network-effect lock-in. webtrees explicitly targets 5.5.1 + supports only a “very small list” of G7 tags on read.
• Gramps 6.0.4 (Aug 2025); Family Tree Maker 2024 (Software MacKiev, May 2025).
• 23andMe filed Chapter 11 in March 2025 — raw-data download still active mid-2026 but at-risk; vendor-lock-in alarm bell for consumer DNA data. GEDmatch (Verogen → Qiagen) remains the cross-vendor comparison hub of record.
• PAF (Personal Ancestral File) discontinued 2013, last update 2002.

Construction / BIM:

• IFC 4.3 = ISO 16739-1:2024 (approved 4 Jan 2024); IFC 4.3.2 docs current. Brought rail/road/bridge/ports into openBIM scope.

• IDS 1.0 official 2024-06-01 — supersedes mvdXML for BIM information requirements.
• BCF 3.0 current with Documents folder addition.
• gbXML 8.01 current.
• Brick Schema 1.4.4 (2025-05-01); Brick merged with RealEstateCore in 1.4.0.
• ISO 19650 P1-3 revisions in public consultation since 2026-03-10, expected 2027.
• OpenStudio 3.11.0 + EnergyPlus 25.2.0 (2026).
• CIM XML (IEC 61970) is the electrical-grid CIM, easily confused with generic BIM.

Build process

• 4 parallel sub-agents in background, all completed first try.
• Wall-clock: ~5 minutes parallel + ~1 minute index/roadmap.
• All four agents avoided broken Languages/xml/html/css cross-links per the explicit hard rule.

• MFA 3.3.9 (Feb 2026); MaryTTS frozen at 5.2.1 (May 2022, maintenance-only); CMUdict 0.7b (Nov 2014) still canonical.
• Classical phoneme-intermediate TTS is now the low-resource/controllability path, not the flagship — gpt-realtime, ElevenLabs v3, XTTS, F5-TTS bypass phonemes entirely.

OCI / cloud-native:

• OCI 2024 triple-bump: Image v1.1.0 (Feb 15), Runtime v1.2.0 (Feb 18), Distribution v1.1 — first major movement on Image since 2017. Artifact manifest formalisation is the single highest-impact change.
• CloudEvents reached CNCF Graduated 2024-01-25; v1.0 deliberately frozen, all new work in extensions + bindings + CloudEvents SQL (v1 July 2024).
• CUE v0.14 (Mar 2026) added cue get crd; v0.13 made eval-v3 the default.
• Falco v0.43.0 (Jan 2026); graduated CNCF in 2024.
• Dagger CUE SDK was discontinued 2023-12-14 — Dagger pivoted to multi-language SDKs (Go, Python, TS, etc.); now belongs in build-devops not here.

Build process

• 4 parallel sub-agents in background, all completed first try.
• Wall-clock: ~5 minutes parallel + ~1 minute index/roadmap.
• All four agents avoided broken Languages/xml/html/css cross-links per the explicit hard rule.

What’s left after this pass

The library is at 77 families / ~1939 catalogued languages — well past saturation. End-of-curve candidates remaining:

• Astronomy / space-data (FITS, CDF, NetCDF cross-link, VOTable, IVOA)
• Agriculture / FarmingOps (ISOBUS / ISO 11783, ADAPT, AgGateway PAIL)
• Legal contract / smart-clause (Accord Concerto/Ergo, OpenLaw, Catala)
• Semantic web extras (OWL 2 + Profiles, SHACL, ShEx, R2RML, RML)

Six-month deep-note version refresh still scheduled for ~2026-11.

Update — 2026-05-10 (seventeenth Tier 3 expansion pass — post-saturation batch)

Added 4 more family-index notes: astronomy-space, agriculture-farming, legal-contract, semantic-web. Library now 142 files, 81 family indexes, ~2040 catalogued languages — crossed the 2000-language threshold.

New family notes added

• OpenLaw pivoted to AI-assisted legal access with $3.5M seed July 2025.
• Aragon BORGs (Bylaws-Onchain-Registered-Governance) shipped Sept 2025 — bridge between smart-contract and legal-contract worlds.

Semantic web:

• RDF 1.2 is W3C Candidate Recommendation, Rec NET 2026-05-05 (not yet final).
• SPARQL 1.2 Query WD published 2025-08-14; SPARQL 1.2 Federated Query WD 2026-01-26.
• Brief correction: Schema.org current is v30.0 (2026-03-19), not v27.x.
• SHACL 1.2 has 4 separate FPWDs (Core, SPARQL Extensions, Rules in Dec 2025, Node Expressions early 2026).

What’s left after this pass

The library is at 81 families / ~2040 catalogued languages — past the 2000-language threshold. End-of-curve candidates remaining are highly speculative or naturally already covered:

• GenAI / LLM-runtime config DSLs (HF transformers config.json, vLLM engine config, llama.cpp GGUF, ONNX runtime providers) — overlaps ai-prompt-languages + oci-cloud-native
• Cybersecurity-specialised DSLs deep tier (eBPF KRSI, Falco extensions, AWS GuardDuty filter) — overlaps identity-auth-policy + forensic-evidence
• 3D/AR/VR scene description (OpenUSD, glTF 2.0, X3D, KTX2, WebXR) — overlaps game-engine-scripting + geospatial + construction-bim
• Linguistic-resource publishing (Wiktionary template syntax, DBnary, OntoLex-Lemon) — overlaps nlp-corpus + semantic-web

Six-month deep-note version refresh still scheduled for ~2026-11.

Update — 2026-05-14 (eighteenth Tier 3 expansion pass — final saturation batch)

Added 4 more family-index notes: genai-llm-runtime, cybersec-deep, 3d-scene, linguistic-resources. Library now 146 files, 85 family indexes, ~2163 catalogued languages.

New family notes added

#	Family	File	Approx count
82	GenAI / LLM-runtime / model-serving	Tier3/genai-llm-runtime.md	~30
83	Cybersecurity deep-tier (vendor / eBPF / SAST)	Tier3/cybersec-deep.md	~32
84	3D / AR / VR scene description	Tier3/3d-scene.md	~33
85	Linguistic-resource publishing / lexicon	Tier3/linguistic-resources.md	~28

Notable findings flagged this pass

GenAI / LLM-runtime:

• GGUF v3 + Dynamic GGUF 2.0 (2025) is the local-inference standard.
• Safetensors ~42% HuggingFace Hub coverage (March 2025).
• TGI in maintenance mode since Dec 2025 — added vLLM and TensorRT-LLM as backends earlier in 2025, then HuggingFace deprioritised the project.
• GGUF’s 2024 embedded-Jinja2 chat-template created a security surface (CVE-2024-34359 in llama-cpp-python).
• OpenAI Structured Outputs GA Aug 2024 (GPT-4o-2024-08-06); Anthropic Structured Outputs public beta 2025-11-13.
• Tool-calling vs structured-outputs split has effectively collapsed by 2026.
• GPTQ/AWQ/EXL2 all live in safetensors shards — only GGUF is a genuinely different container.
• Ollama switched Apple Silicon backend to MLX in 2025.

Cybersecurity deep-tier:

• Falco v0.43.1 (2026-04-09); legacy eBPF/gVisor/gRPC deprecated in v0.43.0.
• CodeQL 2.25.4 (2026-05-12) added Swift 6.3.1; 2026 Semantic Delta Engine cuts PR scan ~80%.
• Semgrep Multimodal launched March 2026.
• Linux 6.19 (Feb 8 2026) added Landlock + LSM hardening.
• CVE-2026-43010 (BPF kprobe.multi) fixed mainline 2026-04-15.
• Google completed Wiz acquisition 2026-03-11 ($32B).
• Lacework → Fortinet (Aug 2024) → now FortiCNAPP v26.2.0.
• Microsoft Sentinel UI migrating to Defender portal effective 2026-07-01.

3D / AR / VR:

• OpenUSD 26.05 released 2026-04-24 (Pixar adopted year-month calendar versioning in 2024).
• AOUSD founded August 2023 (Pixar, Apple, NVIDIA, Adobe, Autodesk).
• MaterialX 1.39.4 (Sep 2025); OCIO 2.4 = CY2025 VFX Reference Platform base.
• OpenEXR 3.3.8 (Mar 2026).
• X3D 4.0 ISO/IEC IS published Dec 2023; OpenXR 1.1 (Apr 2024).
• KHR_gaussian_splatting announced Feb 2026 (RC, Q2 2026 ratification expected).
• OpenUSD 26.03 (Mar 2026) added native 3DGS support.
• Emerging 3DGS containers: .splat, SPZ, KSPLAT.

Linguistic-resource publishing:

• OntoLex-Lemon core is a W3C Final Community Group Report (May 2016); lexicog module is separate Final CG Report (Sep 2019); FrAC still a Working Draft in 2026.
• LMF ISO 24613 modular split now complete: Parts 1 (2024), 2 (2020), 3 (2021), 4 (2021), 5 (2022), 6 (2024).
• WN-LMF 1.4 (2024) — brief said 1.3, corrected.
• TEI Lex-0 current release Jul 2025; TEI Guidelines 4.10.0 Aug 2025.
• CIDOC CRM = ISO 21127:2023 (community version 7.1.3).
• DBnary publishes twice-monthly RDF dumps synced to Wikimedia Wiktionary cycle (26+ language editions, 2024).
• Wikibase Lexemes launched 2018 with wikibase-lexeme/-form/-sense datatypes.

Build / infrastructure notes

• 4 parallel sub-agents in background, all completed first try.
• Obsidian Local REST API went offline mid-batch — three of four agents reported fetch failed when running obsidian-research log. The cybersec-deep agent appended directly to today’s session log as a fallback. I appended the other three agents’ log entries inline after they returned.
• Re-index step skipped this pass (REST API down); will catch up on next session.
• Brief corrections caught: WN-LMF 1.4 (not 1.3).

Maintenance applied this pass

• climate-carbon.md cross-link to energy-power added (grid data feeds Scope 2 emissions; OCPP/OCPI EV data feeds fleet emissions). This patched the parallel-agent miss from the fifteenth pass.
• Frontmatter languages_catalogued counts spot-audited — apparent deltas across all 85 family notes are sub-table-separator artifacts in naive row-counting, not real undercounts. The _index uses “~N” approximations regardless, so no mass renumber.

What’s left

The library is functionally complete at 85 families / ~2163 catalogued languages. Further families would require splitting existing ones rather than adding genuinely new ground. Remaining scheduled work:

• Six-month deep-note version refresh (~2026-11): re-verify all 51 Tier 1+2 deep notes against current upstream releases. Highest-velocity to check: Python, Rust, Go, Swift, Java, Lean/Rocq/Agda.
• Obsidian semantic re-index when the Local REST API plugin is back up — adds the 4 new family notes’ chunks to the searchable index.
• GCN Classic VOEvent retirement follow-up when the GCN-over-Kafka migration completes (post-Oct 2025).
