CHANGELOG

Changelog for package mrpt_io

3.3.0 (2026-09-26)

Python bindings: datasets, maps, localization, sensors (+ fixes) (#1429)
changelogs
Contributors: Jose Luis Blanco-Claraco

3.2.0 (2026-09-16)

Merge branch 'develop' into fix/stereo-rectify-map-axis-swap
Contributors: Jose Luis Blanco-Claraco

3.1.4 (2026-09-04)

test(mrpt_io): raise unit test coverage of streams, compression and path helpers (63%->82% lines) (#1392).
fix(mrpt_io): duplicate [mrpt::io::CompressionType]{.title-ref} definition broke including both detect_compression.h and compression_options.h in the same translation unit.
fix(mrpt_io): zip::decompress()'s std::vector overload passed zlib an uninitialized output-buffer capacity.
fix(mrpt_io): CMemoryStream::Seek() from-end offsets were ignored and could underflow on an empty stream.
fix(mrpt_io): CStream::getline() left a stray unwritten byte at end-of-stream.
fix(mrpt_io): vectorNumericFromTextFile() discarded fscanf() failures, never cleared its output vector, and leaked the FILE handle.
Contributors: Jose Luis Blanco-Claraco

3.1.3 (2026-08-12)

3.1.2 (2026-07-07)

3.1.1 (2026-07-04)

3.1.0 (2026-07-03)

3.0.4 (2026-06-17)

3.0.3 (2026-06-15)

Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system (#1365)

* Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system Add unit tests for TTwist3D, TObject2D/TObject3D (serialization and 2D/3D casting), RANSAC line fitting, CFileStream, CPipe, and CDirectoryExplorer. Fix a bug in TObject2D::operator<< and TObject3D::operator<< where serialization always threw "Unexpected type index" regardless of the actual variant content, due to an unconditional THROW_EXCEPTION after the if/else-if chain instead of in an else branch.
- Apply clang-format-14 to new test files
* Fix MSVC build: M_PI_2 is not a standard macro Use M_PI / 2 instead, matching the M_PI definition already provided by mrpt_core's bits_math.h for all platforms.

* Fix CDirectoryExplorer::explore() on Windows to skip "." and ".." entries The Windows (FindFirstFile/FindNextFile) implementation listed "." and ".." as regular directory entries, unlike the POSIX implementation which already skips them. This caused the new CDirectoryExplorer_unittest.cpp tests to fail on Windows CI.

3.0.2 (2026-06-11)

3.0.1 (2026-06-11)

3.0.0 (2026-06-06)

2.20.0 (2026-06-06)

Last release of the 2.x series. Starting from 3.0.0, changes are tracked in each module's own CHANGELOG.rst file.

CHANGELOG

Changelog for package mrpt_io

3.3.0 (2026-09-26)

Python bindings: datasets, maps, localization, sensors (+ fixes) (#1429)
changelogs
Contributors: Jose Luis Blanco-Claraco

3.2.0 (2026-09-16)

Merge branch 'develop' into fix/stereo-rectify-map-axis-swap
Contributors: Jose Luis Blanco-Claraco

3.1.4 (2026-09-04)

test(mrpt_io): raise unit test coverage of streams, compression and path helpers (63%->82% lines) (#1392).
fix(mrpt_io): duplicate [mrpt::io::CompressionType]{.title-ref} definition broke including both detect_compression.h and compression_options.h in the same translation unit.
fix(mrpt_io): zip::decompress()'s std::vector overload passed zlib an uninitialized output-buffer capacity.
fix(mrpt_io): CMemoryStream::Seek() from-end offsets were ignored and could underflow on an empty stream.
fix(mrpt_io): CStream::getline() left a stray unwritten byte at end-of-stream.
fix(mrpt_io): vectorNumericFromTextFile() discarded fscanf() failures, never cleared its output vector, and leaked the FILE handle.

3.0.3 (2026-06-15)

Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system (#1365)

* Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system Add unit tests for TTwist3D, TObject2D/TObject3D (serialization and 2D/3D casting), RANSAC line fitting, CFileStream, CPipe, and CDirectoryExplorer. Fix a bug in TObject2D::operator<< and TObject3D::operator<< where serialization always threw "Unexpected type index" regardless of the actual variant content, due to an unconditional THROW_EXCEPTION after the if/else-if chain instead of in an else branch.
- Apply clang-format-14 to new test files
* Fix MSVC build: M_PI_2 is not a standard macro Use M_PI / 2 instead, matching the M_PI definition already provided by mrpt_core's bits_math.h for all platforms.

* Fix CDirectoryExplorer::explore() on Windows to skip "." and ".." entries The Windows (FindFirstFile/FindNextFile) implementation listed "." and ".." as regular directory entries, unlike the POSIX implementation which already skips them. This caused the new CDirectoryExplorer_unittest.cpp tests to fail on Windows CI.

Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system (#1365)

* Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system Add unit tests for TTwist3D, TObject2D/TObject3D (serialization and 2D/3D casting), RANSAC line fitting, CFileStream, CPipe, and CDirectoryExplorer. Fix a bug in TObject2D::operator<< and TObject3D::operator<< where serialization always threw "Unexpected type index" regardless of the actual variant content, due to an unconditional THROW_EXCEPTION after the if/else-if chain instead of in an else branch.
- Apply clang-format-14 to new test files
* Fix MSVC build: M_PI_2 is not a standard macro Use M_PI / 2 instead, matching the M_PI definition already provided by mrpt_core's bits_math.h for all platforms.

* Fix CDirectoryExplorer::explore() on Windows to skip "." and ".." entries The Windows (FindFirstFile/FindNextFile) implementation listed "." and ".." as regular directory entries, unlike the POSIX implementation which already skips them. This caused the new CDirectoryExplorer_unittest.cpp tests to fail on Windows CI.

CHANGELOG

Changelog for package mrpt_io

3.3.0 (2026-09-26)

Python bindings: datasets, maps, localization, sensors (+ fixes) (#1429)
changelogs
Contributors: Jose Luis Blanco-Claraco

3.2.0 (2026-09-16)

Merge branch 'develop' into fix/stereo-rectify-map-axis-swap
Contributors: Jose Luis Blanco-Claraco

3.1.4 (2026-09-04)

test(mrpt_io): raise unit test coverage of streams, compression and path helpers (63%->82% lines) (#1392).
fix(mrpt_io): duplicate [mrpt::io::CompressionType]{.title-ref} definition broke including both detect_compression.h and compression_options.h in the same translation unit.
fix(mrpt_io): zip::decompress()'s std::vector overload passed zlib an uninitialized output-buffer capacity.
fix(mrpt_io): CMemoryStream::Seek() from-end offsets were ignored and could underflow on an empty stream.
fix(mrpt_io): CStream::getline() left a stray unwritten byte at end-of-stream.
fix(mrpt_io): vectorNumericFromTextFile() discarded fscanf() failures, never cleared its output vector, and leaked the FILE handle.
Contributors: Jose Luis Blanco-Claraco

3.1.3 (2026-08-12)

3.1.2 (2026-07-07)

3.1.1 (2026-07-04)

3.1.0 (2026-07-03)

3.0.4 (2026-06-17)

3.0.3 (2026-06-15)

Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system (#1365)

* Increase unit test coverage for mrpt_math, mrpt_io, mrpt_system Add unit tests for TTwist3D, TObject2D/TObject3D (serialization and 2D/3D casting), RANSAC line fitting, CFileStream, CPipe, and CDirectoryExplorer. Fix a bug in TObject2D::operator<< and TObject3D::operator<< where serialization always threw "Unexpected type index" regardless of the actual variant content, due to an unconditional THROW_EXCEPTION after the if/else-if chain instead of in an else branch.
- Apply clang-format-14 to new test files
* Fix MSVC build: M_PI_2 is not a standard macro Use M_PI / 2 instead, matching the M_PI definition already provided by mrpt_core's bits_math.h for all platforms.

* Fix CDirectoryExplorer::explore() on Windows to skip "." and ".." entries The Windows (FindFirstFile/FindNextFile) implementation listed "." and ".." as regular directory entries, unlike the POSIX implementation which already skips them. This caused the new CDirectoryExplorer_unittest.cpp tests to fail on Windows CI.

3.0.2 (2026-06-11)

3.0.1 (2026-06-11)

3.0.0 (2026-06-06)

2.20.0 (2026-06-06)

Last release of the 2.x series. Starting from 3.0.0, changes are tracked in each module's own CHANGELOG.rst file.
