excerpt: "Overview of all work happening in Vortex"

In October, a lot of focus was on revamping Array evaluation to be fully lazy, by converting their execution
10+
to an Operator model that evaluates into Vectors (fully decompressed, zero-copy to Arrow representation).
11+
This work enables many more optimizations, and also provides unified abstractions for evaluating on
12+
different processor types (CPUs & GPUs).
13+
14+
In parallel, Vortex added experimental support for a GPU Scan, with fused CUDA kernels for decompressing Vortex data
15+
directly on-device.
16+
17+
For an in-depth view of this work, see the [recent talk on Vortex](https://db.cs.cmu.edu/events/futuredata-vortex/)
18+
as part of CMU's Future Data Seminar.
19+
20+
## Core
21+
22+
1. Children of `ZonedLayoutReader` are evaluated lazily. [#5007](https://github.com/vortex-data/vortex/pull/5007)
23+
2. Introduced our own bit-buffer type, allowing for in-place mutation [#4940](https://github.com/vortex-data/vortex/pull/4940)
24+
3. Introduced experimental GPU Scan [#5012](https://github.com/vortex-data/vortex/pull/5012)
25+
26+
## Integrations
27+
28+
### DFT
29+
30+
You can now try Vortex as part of [dft](https://github.com/datafusion-contrib/datafusion-dft), a batteries-included suite of data tools based on Apache DataFusion.
31+
32+
### DataFusion
33+
34+
1. Added support for pushing down filters onto fields of struct columns. #5024
35+
36+
### DuckDB
37+
38+
As of DuckDB 1.4.2, Vortex is included as a core extension in DuckDB. See their [docs](https://duckdb.org/docs/stable/core_extensions/vortex) for more details.
39+
40+
## Acknowledgments
41+
42+
We want to thank to anyone who has tried Vortex, provided feedback, asked question and filed issues.
43+
44+
Special thanks go for all the contributors who took the time and care to contribute to Vortex this month (in descending count of commits):
