+# Releasing lonboard 0.13!
+
+Lonboard is a Python library for fast, interactive geospatial vector data visualization in Jupyter.
+
+This post gives an overview of what's new in Lonboard version 0.13.
+
+<!-- more -->
+
+Refer to the [changelog] for all updates.
+
+## New layer types: H3, S2, Geohash, A5
+
+Lonboard supports new layer types for [H3][h3], [S2][s2], [Geohash][geohash], and [A5][a5] data.
+
+[h3]: https://h3geo.org/
+[a5]: https://a5geo.org/
+[s2]: http://s2geometry.io/
+[geohash]: https://en.wikipedia.org/wiki/Geohash
+
+- [`H3HexagonLayer`][lonboard.H3HexagonLayer]: render hexagons from the [H3][h3] geospatial indexing system
+- [`S2Layer`][lonboard.S2Layer]: render polygons based on the [S2][s2] geospatial indexing system.
+- [`A5Layer`][lonboard.A5Layer]: render polygons based on the [A5][a5] geospatial indexing system.
+- [`GeohashLayer`][lonboard.GeohashLayer]: render polygons based on the [Geohash][geohash] geospatial indexing system.
+
+![](../../assets/kontur-h3.jpg)
+
+> Screenshot from [H3 Population](../../../../../examples/kontur_pop) example
+
+Additionally, the [HeatmapLayer][lonboard.HeatmapLayer], which has been broken since Lonboard v0.10 due to upstream changes in deck.gl, has been fixed and is now functional again. (Thanks to @felixpalmer for [fixing this upstream](https://github.com/visgl/deck.gl/pull/9787)!).
+
+## Interleaved rendering with Maplibre
+
+When rendering dense visualizations, the data can obscure helpful elements of the basemap, removing spatial context from the visualization.
+
+It's now possible to render Lonboard data layers interleaved in the Maplibre layer stack. This means Maplibre text labels can be rendered above your Lonboard-rendered data.
+
+![](../../assets/interleaved-labels.jpg)
+
+> Screenshot from [H3 Population](../../../../../examples/interleaved-labels) example
+
+To do this:
+
+- Set [`before_id`](../../../../../api/layers/base-layer#lonboard.BaseLayer.before_id) on your layer as the value of the Maplibre layer `id` you want the Lonboard layer to be under. See [`before_id`](../../../../../api/layers/base-layer#lonboard.BaseLayer.before_id) for more information.
+- Create a new basemap [set to `interleaved` mode][lonboard.basemap.MaplibreBasemap.mode]:
+- Pass the basemap to the `Map` constructor.
+
+```py
+from lonboard.basemap import MaplibreBasemap
+from lonboard import Map, ScatterplotLayer
+
+# Example layer ID when using Carto basemap styles
+layer = ScatterplotLayer(..., before_id="watername_ocean")
+basemap = MaplibreBasemap(mode="interleaved")
+m = Map(layer, basemap=basemap)
+```
+
+## Map controls: scale, fullscreen, navigation
+
+Common UI elements that we call "Controls" are now supported in Lonboard maps. In this release, this includes three types of controls:
+
+- Scale control: shows a scale bar on the map
+- Fullscreen control: button to toggle fullscreen mode
+- Navigation control: zoom in/out buttons and a compass
+
+These three controls are rendered on the map by default, but can be customized via the [`Map.controls`][lonboard.Map.controls] attribute. See [`lonboard.controls`][] for more information.
+
+![](../../assets/controls-example.jpg)
+
+## Performance improvements
+
+First and foremost, I learned there was _severe bug_ in which the string representation (aka `repr`) of the [`table` attribute][lonboard.BaseArrowLayer.table] was being generated during map display. In conjunction with [an upstream issue](https://github.com/kylebarron/arro3/issues/432), this made it _very slow_ to render a map for datasets with many coordinates in a single row (such as polygons representing administrative boundaries). https://github.com/developmentseed/lonboard/pull/1015 **improved the Python-side of rendering by 99% in this case**, from 12 seconds to 5 milliseconds.
+
+In https://github.com/developmentseed/lonboard/pull/902 we now fully parallelize the Parquet file generation in a thread pool on the Python side, leading to 4x faster Parquet serialization.
+
+In https://github.com/developmentseed/lonboard/pull/954 we improve the Polygon rendering performance on the JavaScript side and remove a network request for a dependency needed to perform multi-threaded preparation for Polygon data rendering.
+
+In general, Lonboard data rendering should feel instantaneous. If it's especially slow, on the order of ~10 seconds, [open an issue](https://github.com/developmentseed/lonboard/issues/new/choose) with your dataset to discuss.
+
