v20.3.6

This release addresses a number of bugs uncovered in a recent security audit of the code.

v20.3.5

This release adds true single threaded support to the library. Previously, setting library to single threaded created a single worker thread, and an asynch thread, resulting in a total of 3 threads including the calling thread. Now, no new threads are created.

Also fixed are two decompression issues:

1. palette images were corrupted in certain cases
2. images using bypass mode were corrupted in certain cases

v20.3.4

This release fixes a long-standing bug where region decompression for certain regions on a multi-tile image could result in empty-block artifacts.

v20.3.3

This release contains the following enhancements:

1. reduced coordinates can be used when scheduling reduced swaths
2. network fetch can select only relevant packets when TLM and PLT markers are both present

v20.3.2

This release:

1. adds an opt-in fast path for lossless 12 bit decompression with MCT (including DCI decompression)
2. fixes integration with GDAL

v20.3.1

This release adds a number of speed and memory optimizations:

1. 16 bit path for compression and decompression
2. SIMD improvements

v20.3.0

This point release encompasses the many new features added since v20.2.0

v20.2.9

This release enhances existing network authentication support.

v20.2.8

This release:

1. fixes a transcode bug for EPH/SOP markers - will now work with or without TLM marker present
2. fixes a CDEF colour association validation bug that was rejecting RGBA images
3. adds support for vsicurl network files

v20.2.7

This is a bug fix release, fixing a number of issues caught by OSS-Fuzz.
