Release notes

Sourced from maplibre/martin's releases.

martin-v1.15.0

Hillshade postprocessing

Martin can now bake a hillshade from a source serving Mapzen normal tiles, so clients get shaded relief instead of a normal map they have to shade themselves.

passthrough:
  sources:
    terrain:
      url: https://elevation-tiles-prod.s3.amazonaws.com/normal/{z}/{x}/{y}.png
      maxzoom: 14
      convert_to_hillshade: auto

auto bakes with the defaults, a map of settings overrides light angle, exaggeration, contrast, banding and output format (png, webp or jxl). It is a per-source key only, since an inherited value would also reach sources that cannot be shaded. Baking reads a 3x3 neighborhood so tiles do not have seams at their edges, and caches the normal maps rather than the baked output. See the documentation. Done in #3180.

Contour postprocessing

convert_to_contour traces contour lines from a source serving Mapzen Terrarium elevation tiles and serves them as MVT. Each tile has one contour layer of linestrings tagged with their elevation (ele) and whether they are a major line (major), with the interval per zoom set by zoom_intervals. Unlike hillshade the output is vector, so the client styles and labels the lines itself. See the documentation. Done in #3183.

Added

• JPEG XL: jxl tiles are detected and decoded (via jxl-oxide), and hillshade can encode its output as lossless JPEG XL (via zune-jpegxl), which is usually smaller than PNG or lossless WebP (#3181)
• (cache-control) per-source Cache-Control overrides on top of the server-wide default. A composite request only uses one if all of its sources are configured with the same value (#3167, #3148)
• (postgres) --ssl-cert and --ssl-key flags for the client certificate and key, mirroring --ca-root-file (#3150 by @​reddynitish)
• (config) warn once at startup when Martin falls back to a legacy Postgres env var (DATABASE_URL, DEFAULT_SRID, PGSSLCERT, PGSSLKEY, PGSSLROOTCERT), naming the config key that replaces it. All five keep working, the removal is deferred to v2 (#3151 by @​reddynitish)

Fixed

• (mbtiles) avoid a full tiles scan when computing min/max zoom. Startup on a 5M tile file drops from 367ms to 203ms flat, and from 1650ms to 203ms normalized (#3185)
• (catalog) serialize the catalog in a stable key order, so /catalog no longer differs between restarts (#3189)
• (fonts) redirect glyph URLs ending in .pbf instead of answering 404, so OpenMapTiles styles work unedited (#3187)
• (pmtiles) pick up the ECS and EKS credential env vars, so S3 sources use the task role on Fargate and EKS (#3165)
• (reload) keep per-source convert_to_* overrides for file-backed (#3160) and Postgres (#3144) sources
• (config) gate the resolve_process_config imports on _process (#3191)
• fix cors logging logging unrecognisable (#3136)
• (deps) update npm dependencies (#3177, #3175)

Other

• (pmtiles) open file sources concurrently and share one client per store (#3131)
• Reload and config refactors: the reloader is now the single writer of Postgres sources, the tile reloaders moved into TileReloaders, file source ids resolve before the sources open, and Discovery::discover returns its warnings (#3130, #3178, #3190, #3133, #3142, #3143)

... (truncated)
