The daily promotion moves to 20:00 UTC (21:00 in Paris in winter time):
PROMOTE_AT and promote.yml's cron (20:07, retries until 21:37), with the docs
that give the time. A launcher left open on Nightly looks for new releases
every 30 minutes; Stable keeps 4 hours. The launcher README's Settings
screenshot shows the Updates choice.

The launcher's "Beta builds" switch becomes an Updates choice of two channels,
stored as "update_channel": "stable" | "nightly" (an old "beta_builds": true
reads as nightly). The CLI (update-channel) and MCP (update_channel) show and
set it, and list each release's channel as stable or nightly.
Nightly ships constantly: the release train waits 5 minutes for a merge wave to
settle (20 at most) instead of 15 (an hour). Stable moves once a day:
promote.yml runs at 19:00 UTC (retries until 20:37) and promotes the newest beta
that had been out 6 hours by 19:00, so late runs and retries pick the same one.
The stalled-promotion issue waits 30 hours. Release notes, docs, the website's
install and FAQ pages say Stable and Nightly.

Pack-wide numbers after the modpacks-12 PRs (#1175, #1176, #1177, #1191):
structures that start, processors carried and dropped per mod, content,
load time and the play-through, and the gaps ranked by how much a player
notices them.

The game sends an anonymous ping once a minute while it runs (a random
session ID kept only in memory, the version, the platform, whether a LAN
or friends world is open). The telemetry server counts sessions seen in
the last 2 minutes, in memory only, with its own per-address rate limit
and a session cap, and serves rounded counts at GET /v1/live. The
launcher shows "N playing now" on the Play page when the count is
reachable, and tells players what the ping holds on the first-run
question, in Settings, and once on the Play page for players who
answered before. docs/telemetry.md and the privacy page say the same.
Like the rest of telemetry, nothing is sent until HORIZON_TELEMETRY_URL
is set or DEFAULT_ENDPOINT gets a server.

Formations' PiecedStructure starts like its SimpleStructure, then lays out
the element's jigsaw children with vanilla's jigsaw. The game's jigsaw
assembler now exposes its child layout (add_children) for a start piece
placed by another structure type; horizon:formations reads horizon:pieced
(max_depth, max_distance_from_center), which carry writes for
formations:pieced.

ctov:modular_compat runs another processor list only when the mod it names
is loaded: carry writes that list in when the mod is ported along and takes
the hook out otherwise (142 copies in ATM10, all for Nature's Spirit).
Repurposed Structures' mineshaft_sky_view_processor (71 lists) becomes the
game's horizon:mineshaft_sky_view: nothing at or above the world's
OCEAN_FLOOR_WG height, except plain rails over a block that can occlude,
waterlogged where the world holds water. Placement contexts gain
can_occlude.

Carry maps mostructures:generic to vanilla's jigsaw with horizon:start_checks
(terrain_radius 2, terrain_range = heightRange) and mostructures:type to a
random spread with the config's default spacing and separation and its sets
to avoid as horizon:exclusion_zone. The game's exclusion zone gains
"their_zones": false, which tests the avoided sets by spread and frequency
alone, as ModStructurePlacement does.

HORIZON_SPIKES spans keep the thread's CPU time beside their wall time,
and the slow-frame line gives the render thread's CPU time in the frame.
A span that mostly waited (for the GPU, a lock or a core) prints both
(`submit 30.2/0.1`), so a frame that waited reads apart from one that
worked. Found the cause of #678's long frames: the render thread losing
its core in queue.submit.

A new Horizon Extras option, Lighting > Dynamic lights (`dynamicLights`,
off by default): a torch, lantern or other light-emitting item held by a
player or mob, dropped as an item, or any entity on fire lights the blocks,
entities and hand around it, as LambDynamicLights and OptiFine do.
Client-only and at render time: the light engine, chunk meshes and saves
never see it. Each frame the game picks the 16 sources nearest the camera
(dynamic_light::select) and passes them in Globals; terrain.wgsl and
entity.wgsl raise each vertex's block light to `level - distance` when that
is brighter. Off, the count in globals.time.z is 0, nothing is gathered and
the shaders' loop runs zero times, so no pipeline is rebuilt either way.
An item glows like its block's default state (torch 14, lantern and
glowstone 15, lit redstone torch 7); a lava bucket 15; burning entities 15.

The Shader Pack setting cycled through what shaderpacks/ held, so with the
folder empty (or the packs in the launcher's version folder, as brabus_ had
them) it silently stayed Off. The row now opens a Shader Packs page: a
sidebar section in the Horizon menus, Video Settings > Shader Packs... in
the Classic ones. It shows the game home's shaderpacks/ path and an Open
Folder button (made if missing), says when there is no pack, and lists one
switch per pack. A pack that fails to load says why on its row. The list is
read again every second while the page shows.

A Mods page between Versions and Modpacks: resource packs, shader packs and
modpacks as tabs, a search field, Show everything, and Modrinth / CurseForge
once CurseForge has a key. Results are index rows with summary, author,
downloads, source, licence and how well each runs (with the reason), Page and
Install (Import for a modpack, which then shows on the Modpacks page).
Installed packs list their version, source, file and the checksum they were
checked against, with Update and Remove. Searches, installs and update checks
run on threads; stale search answers are dropped.

browser::installed installs a pack and its required dependencies into
resourcepacks/ or shaderpacks/, every file checked before any download
(a dependency that is a Java mod stops it) and checksum-verified on the
way in; mod-browser.json records source, version, file and checksum.
Update swaps the file, remove deletes only what the browser installed (a
player's own file of the same name is never overwritten). A modpack is
downloaded, checked, and imported through the Modpacks page's pipeline.
The CLI gains `mods list|search|install|update|remove`.

The launcher's core gains `browser`: search Modrinth for what Horizon loads
(resource packs, Iris/OptiFine shader packs, modpacks; never Java mod jars),
say how well each result runs, pick the newest version that runs, and
download a file only from Modrinth's or CurseForge's file servers, with a
plain file name, kept only when its size and SHA-512 (SHA-1 on CurseForge)
match. CurseForge is a pluggable source that stays off until an API key
exists (HORIZON_CURSEFORGE_API_KEY at run time or build time; the launcher
workflow passes the repository secret). docs/mod-browser.md.

🤖 Agent: merged. Verify passes. Local integration of #1121–#1125 on main 2d586fac: parity --changed, all 101 affected harnesses pass. Screenshots in the body.
Ludovic decided (2026-10-21) that the next release is 0.2 for both the game and the launcher, with one
clear scheme instead of vYYYY.MM.DD(.N) and launcher-vX.Y.Z. This page is the design the other 0.2
pull requests implement:
- tags vX.Y.Z and launcher@X.Y.Z (launcher-v0.2.0 is taken), on a line in .github/release-line.txt;
betas stay pre-releases under their final tag; semver pre-release tags reserved for previews;
- one order for every reader: each 0.2 tag above every tag from before;
- how release.yml, launcher.yml and promote.yml map onto it (HORIZON_VERSION, HORIZON_LAUNCHER_TAG);
- what launchers and servers from before 0.2 do with it, and the bridges that move them
(launcher-v0.17.0, the last dated game release made latest before v0.2.0);
- the orchestrator's steps for the day Ludovic says go, freeze off included.

Classic Extras laid every setting out as a full-width button. Pair each
section's buttons as vanilla's OptionsList.addSmall does (the same layout as
Video Settings), and shorten "Lower sensitivity while zoomed" to "Slower
turning" so it fits a half-width button.
Horizon's Extras page shows a switch's own settings (Zoom key, Minimap size,
FPS corner...) only while that switch is on, so it stays one row per extra
as the list grows. Classic keeps every button, as vanilla screens do.

docs/versioning.md: with .github/release-line.txt (MAJOR.MINOR) the train tags game releases
vMAJOR.MINOR.PATCH and launcher releases launcher@MAJOR.MINOR.PATCH, the patch after the newest
release on the line; the line's first release goes out at once (still not while RELEASES_PAUSED is
set). Without the file nothing changes: vYYYY.MM.DD[.N] and launcher-vX.Y.Z. The file is not added
here; the switch to 0.2 is a separate one-line pull request for the day Ludovic says go.
- tag_key: every 0.2 tag ranks above every dated or launcher-v tag; semver order within, a
pre-release before its release. release_channels.py uses the same key and tag test, so promotion
and "latest only moves forward" work across the switch.
- A line's first release says so in its notes; 0.2.0's explains the numbering and how a server
that says it is up to date takes it (horizon-server update --version v0.2.0).
- launcher.yml strips either prefix for HORIZON_LAUNCHER_VERSION and passes HORIZON_LAUNCHER_TAG,
which the launcher uses to know its own line.

🤖 Agent: merged after integration C: the desktop ran 322/325 harnesses on main + #1088–#1093, and its 3 failures were the known dedicated_server flake plus the two display harnesses; world_reopen and save_roundtrip pass on the Mac mini (main + the six branches).
🤖 Agent: merged. Creative pick block in inventories (fixes#1048, Visivel). Integration proof (main + #1079#1081#1082#1083#1085#1086#1087), 2026-10-21: desktop parity 103/105; the 2 others (world_reopen, save_roundtrip) need a display and pass on the Mac mini. Verify passed.
Measured on an Intel HD 620 (#897): rain and snow cost about 3 ms of GPU
per frame there, most of it from the weather radius; FXAA about 0.8 ms;
cave culling saves about 0.6 ms; mipmaps cost nothing measurable and
clouds about 0.1 ms. A new Cost::Saves tag ("Saves time", in the success
colour) marks a setting that makes frames faster when on.

The middle button (keyPickItem) over an inventory or the creative screen no
longer clicks like the left button: with infinite materials it clones the
hovered stack at full size (CLONE) or, holding a stack, drags full stacks into
slots (quick craft type 2); otherwise it does nothing. Agents can middle-click
widgets (click ID middle), and creative slots are ui widgets now.
