| PR | Contribution |
|---|---|
| #4171 | Robustness: a Tj operator with a number instead of a string made extract_text() raise TypeError; it is now skipped and the text around it kept |
| #4166 | Robustness: a TJ operator with a number instead of an array made extract_text() raise TypeError; it is now skipped and the text around it kept |
| #4165 | Robustness: a bare Do operator made extract_text() raise IndexError from inside its own warning; it is now skipped and the text around it kept |
| #4163 | Robustness: a /FirstChar that is null, a name or a string crashed layout-mode extract_text() with TypeError |
| #4155 | Bug fix (6.19.0 regression): text shown before a change of direction, such as digits beside Arabic, was dropped from extract_text() |
| #4138 | Robustness: a /Font resource that is a number, string or array crashed extract_text() with TypeError, in plain and layout mode |
| #4123 | Bug fix: a malformed rectangle failed with a bare AssertionError that vanished under python -O; it now raises a ValueError naming the values |
| #4098 | Robustness: an outline /A action missing the required /S subtype raised KeyError, making the whole outline unreadable |
| #4119 | Robustness: a /Type0 font omitting /DescendantFonts raised a bare KeyError out of extract_text() |
| #4118 | Robustness: a /Widths entry holding a string was passed to int(), raising ValueError during text extraction |
| #4102 | Robustness: a /Kids entry that is not an array crashed reader.page_labels |
| #4099 | Bug fix: add_named_destination wrote a hardcoded /FitH top of 826, pointing viewers past the top of the page |
| #4080 | Robustness: add_outline_item raised UnboundLocalError instead of naming an unsupported page_number type |
| #4074 | Bug fix: a string rect for add_uri collapsed to 0, leaving the link with no clickable area |
| #4069 | Robustness: insert_blank_page looked up the size of a page that did not exist yet on an empty writer |
| #4064 | Robustness: a malformed /XFA entry raised TypeError or StopIteration out of reader.xfa |
| #4058 | Robustness: a font /Encoding whose /Differences is not an array crashed text extraction |
| #4054 | Robustness: page /Resources that is not a dictionary crashed extract_text() on the /Font lookup |
| #4048 | Robustness: a /Kids entry that is not a dictionary crashed the page tree walk |
| #4046 | Robustness: an /Annots entry that is not an array crashed anything iterating page.annotations |
| #4041 | Robustness: a page box that is not an array failed with an error naming neither the box nor the problem |
| #4039 | Robustness: a name tree node whose /Names or /Kids is not an array crashed reader.named_destinations |
| #4038 | Typing: read_object was annotated to return an int or str it can never produce, forcing six suppressions across its callers |
| #4031 | Robustness: a form field entry that is not a dictionary crashed reader.get_fields() |
| #4030 | Robustness: /XObject resources that are not a dictionary crashed page.images |
| #4029 | Robustness: an /AcroForm entry that is not a dictionary crashed reader.get_fields() |
| #4023 | Robustness: an /Outlines entry that is not a dictionary crashed reader.outline |
| #4022 | Robustness: a malformed /PageLabels entry crashed reader.page_labels |
| #4021 | Robustness: a malformed /ViewerPreferences entry raised AttributeError |
| #4020 | Robustness: a malformed /Dests or /Names entry crashed reader.named_destinations |
| #4019 | Robustness: a malformed AcroForm /Fields entry crashed get_fields() |
| #4018 | Robustness: an outline node that is not a dictionary crashed reader.outline |
| #4017 | An unknown page label style was written into /S and then silently dropped on read |
| #4016 | An out-of-range page surfaced as a bare IndexError from the kids array |
| #4014 | The four area and clip preferences were declared with no acceptable values, so any name passed |
| #4013 | /PrintPageRange holds page pairs, so an odd-length array leaves a range without its end |
| #4012 | /NumCopies accepted a negative count no reader can interpret |
| #4011 | /PrintScaling was declared with an empty list of acceptable values, so nothing checked it |
| #4010 | Bug fix: the page layout warning printed a set of an empty string and every layout run together |
| #4009 | A page box could be set to two values but not read back, since the getter needs four |
| #4005 | Bug fix: number2uppercase_roman_numeral(-1) returned CMXCIX instead of refusing a non-positive number |
| #4004 | Bug fix: PageRange("::0") was accepted and reported valid, but the range only failed once applied |
| #4003 | Form field flags were passed as a bare 1 where the docs point at the FfBits enum |
| #4002 | Bug fix: two callers passed the raw /Font entry to a function reading it as a dictionary - it worked only because IndirectObject forwards attributes |
| #4000 | expat passes an int for is_parameter_entity while typeshed declares a bool - records why the annotation stays |
| #3997 | The docs set annotation.flags = 4 under a comment pointing readers at AnnotationFlag |
| #3996 | Bug fix: a CID font's /W array may hold real numbers, so a width of 443.35938 landed in a dict[str, int] |
| #3995 | XmpInformation was typed for a ContentStream, a sibling of the DecodedStreamObject the /Metadata stream actually is |
| #3991 | The annotation border was declared an ArrayObject while the documented usage is a plain list |
| #3990 | Fit was typed for a tuple, but the destination builder unpacks the PDF array and hands over a list |
| #3989 | The layout-mode extractor passes a ChainMap into a function annotated for two lists, behind a type: ignore |
| #3988 | Both name-tree walks cast to TreeObject on objects that are plain dictionaries at runtime |
| #3986 | The annotation list holds IndirectObject references, not the DictionaryObject it was declared as |
| #3985 | Returned two empty lists from a function annotated None, hidden behind a type: ignore |
| #3984 | Bug fix: RectangleObject was typed for a tuple, but every caller inside pypdf passes the ArrayObject read from the PDF |
| #3983 | Bug fix: iterating a PDF dictionary yields keys, so the AcroForm font walk collected nothing — form fields inheriting a document-level font came back with an empty font set |
| #3972 | A compressed cross-reference stream is an EncodedStreamObject, a sibling of the ContentStream it was declared as |
| #3971 | Bug fix: a stream without an explicit /DecodeParms handed every filter a plain dict, but the decoders are typed for a DictionaryObject |
| #3970 | Bug fix: the object-translation table is declared int-to-int, but each entry also stores the source document under a "PreventGC" key — two type: ignore comments hid the mismatch |
| #3969 | Release tooling: the version bump always assumed a patch release, so enhancements had to be corrected by hand — now derived from the generated changelog sections |
| #3960 | Bug fix: PdfWriterProtocol declares _reader, but PdfWriter only set it in incremental mode — so a normal writer failed the protocol it is passed as |
| #3957 | Bug fix: pages was annotated list[PageObject] but returns a lazy _VirtualList, so type checkers accepted reader.pages.append(...) — which raises at runtime |
| #3943 | Bug fix: an explicit /Decode array replaced the Adobe CMYK inversion instead of composing with it, leaving extracted images colour-inverted |
| #3938 | Bug fix: low-bit expansion never ran for unfiltered/inline images, raising unrecognized image mode |
| #3929 | Bug fix: low-bit /DeviceRGB images decoded as RGB instead of palette — broken image extraction |

fonttools/fonttools 5.3k★ — 7 merged (click to expand)
| PR | Contribution |
|---|---|
| #4269 | Bug fix: a non-ASCII OS/2 Vendor compiled and then crashed on save with UnicodeEncodeError; feaLib now rejects it with the line |
| #4268 | Bug fix: a STAT axis location with no or too many values was skipped and crashed later with KeyError; feaLib now rejects it with the line |
| #4267 | Bug fix: a name string feaLib could not encode or decode (an unpaired surrogate, an emoji in Mac Roman) raised a bare UnicodeError; it now raises FeatureLibError at the string |
| #4266 | Bug fix: a UnicodeRange bit outside 0-127 passed the feaLib parser and failed later with a bare ValueError; it now raises FeatureLibError with the line |
| #4263 | Bug fix: a BaseScriptList without a matching BaseTagList crashed feaLib with UnboundLocalError or a bare ValueError; both now raise FeatureLibError with the line |
| #4259 | Bug fix: feaLib wrote a short OS/2 Vendor ID padded with NUL bytes; it is now padded with spaces as the OpenType spec requires |
| #4253 | Bug fix: a CFF font with a non-ASCII name could be saved but not read back — the Name INDEX was decoded as ASCII while the compiler writes latin-1 |

| #1984 | Bug fix: write_html() raised KeyError: 'href' on a named anchor (<a name="intro">); its text is now rendered as plain text |
