+included in the release package and by the Git commit history.
+
+Major changes

+  tags by default
+
+* tif_predict.c: speed-up decompression in some cases.
+
+API/ABI breaks:
+
+* None
+
+Bug fixes:
+
+* tif_fax3: For fax group 3 data if no EOL is detected, reading is retried
+  without synchronisation for EOLs. (fixes :issue:`54`)
+
+* Updating TIFFMergeFieldInfo() with read_count=write_count=0 for FIELD_IGNORE.
+  Updating TIFFMergeFieldInfo() with read_count=write_count=0 for FIELD_IGNORE.
+  Improving handling when field_name = NULL.
+  (fixes :issue:`532`)
+
+* tiff.h: add COMPRESSION_JXL_DNG_1_7=52546 as used for JPEGXL compression in 
+  the DNG 1.7 specification
+
+* TIFFWriteDirectorySec: Increment string length for ASCII tags for codec tags
+  defined with FIELD_xxx bits, as it is done for FIELD_CUSTOM tags.
+  (fixes :issue:`648`)
+
+* Do not error out on a tag whose tag count value is zero, just issue a warning.
+  Fix parsing a private tag 0x80a6 (fixes :issue:`647`)
+
+* TIFFDefaultTransferFunction(): give up beyond td_bitspersample = 24
+  (Fixes https://github.com/OSGeo/gdal/issues/10875)
+
+* tif_getimage.c: Remove unnecessary calls to TIFFRGBAImageOK()
+  (fixes :issue:`175`)
+
+* Fix writing a Predictor=3 file with non-native endianness

+   read / nullptr dereference) in case of out-of-memory situation when dealing
+   with custom tags (fixes :issue:`663`)
+
+* tif_fax3.c: Error out for CCITT fax encoding if SamplesPerPixel is not equal
+  1 and PlanarConfiguration = Contiguous (fixes :issue:`26`)

+* tif_fax3.c: error out after a number of times end-of-line or unexpected bad
+  code words have been reached. (fixes :issue:`670`)
+
+* Fix memory leak in TIFFSetupStrips() (fixes :issue:`665`)

+  (fixes :issue:`5`)
+
+* tif_getimage.c: update some integer overflow checks (fixes :issue:`79`)
+
+* tif_getimage.c: Fix buffer underflow crash for less raster rows at
+  TIFFReadRGBAImageOriented() (fixes :issue:`704`)
+
+* TIFFReadRGBAImage(): several fixes to avoid buffer overflows.

+* Correct passing arguments to TIFFCvtIEEEFloatToNative() and
+  TIFFCvtIEEEDoubleToNative() if HAVE_IEEEFP is not defined. (fixes
+  :issue:`699`)
+
+* LZWDecode(): avoid nullptr dereference when trying to read again after EOI 
+  marker has been found with remaining output bytes (fixes :issue:`698`)

+  8/12bit dual mode, introduced in libjpeg-turbo 2.2, which was actually
+  released as 3.0. (fixes :issue:`717`)
+
+* add assert for TIFFReadCustomDirectory infoarray check.
+
+Other changes:
+
+* tif_jpeg.c: use JPEG_MAX_DIMENSION constant instead of hard-coded 65535 value
+
+* tif_lzw.c / tif_packbits.c: use NULL instead of 0.

+
+* tif_lerc.c: add missing casts
+
+* Merge several functions implemented twice in different modules.
+  (see :issue:`154`)

+  (tiffconf.h) added.
+
