## [0.36.1] - 2026-07-27

### Fixed

- Fixed a regression in 0.36.0 that broke Strict OOXML (ISO/IEC 29500)
  `_rels/.rels` links.

  [PR #681]: https://github.com/tafia/calamine/pull/681

- Fixed XLS string handling to preserve empty strings instead of discarding
  them. [PR #679].

  [PR #679]: https://github.com/tafia/calamine/pull/679

- Fixed XLSB workbook parsing to consume the body of unhandled workbook-global
  records. A leftover body was misread as the next record id, which either
  silently dropped the worksheet or panicked from an empty buffer. [PR #675].

  [PR #675]: https://github.com/tafia/calamine/pull/675


## [0.36.0] - 2026-07-06

### Added

- Added an XLSX streaming API for cell and formula records, including shared
  formula metadata. There are two new APIs:
  `XlsxCellReader::next_cell_with_formula()` and
  `XlsxCellReader::next_cell_with_formula_metadata()`. Previously it required 2
  separate reads to get similar information. [PR #654].

  [PR #654]: https://github.com/tafia/calamine/pull/654

- Added a per-sheet, lazy XLSX API to read worksheet hyperlinks:
  `Xlsx::hyperlinks_by_sheet_name()` and `Xlsx::hyperlinks_by_sheet_id()`. Each
  hyperlink reports its anchor range (`Dimensions`), external target
  (URL/file/mailto), optional internal location, displayed text, and optional
  tooltip. [PR #659].

  [PR #659]: https://github.com/tafia/calamine/pull/659

- Extended the `picture` feature to also extract cell position information and
  the raw image data, and to handle newer Excel 365 style embedded images.
  [PR #652].

  [PR #652]: https://github.com/tafia/calamine/pull/652

- Added support for reading XLSX rich string (`rstring`) records. [Issue #655].

  [Issue #655]: https://github.com/tafia/calamine/issues/655

### Changed

- Updated dependencies and the minimum supported Rust version (MSRV) for
  release 0.36.0:

  - `atoi_simd`: 0.17 → 0.18. [PR #672]
  - `zip`: 7.0 → 8.6. This raises the MSRV from 1.83 to 1.88. [PR #672]
  - `quick-xml`: 0.39 → 0.41, to address advisories [RUSTSEC-2026-0194] and
    [RUSTSEC-2026-0195]. [Issue #674].

  [PR #672]: https://github.com/tafia/calamine/pull/672
  [Issue #674]: https://github.com/tafia/calamine/issues/674
  [RUSTSEC-2026-0194]: https://rustsec.org/advisories/RUSTSEC-2026-0194.html
  [RUSTSEC-2026-0195]: https://rustsec.org/advisories/RUSTSEC-2026-0195.html

- Performance improvements:
  - Custom zero-overhead attribute extraction and optimized `local_name`
    matching. [PR #621]
  - Optimized buffer use for XLSB cell reads. [PR #662]

  [PR #621]: https://github.com/tafia/calamine/pull/621
  [PR #662]: https://github.com/tafia/calamine/pull/662

- Refactored and unified the merged-cell handling APIs. For historical reasons
  the XLSX methods for accessing merged cells were duplicated. This change
  introduces a cleaner API, deprecates the older methods, and aligns the XLS
  merged-cell handling with the new XLSX APIs. [Issue #536].

  [Issue #536]: https://github.com/tafia/calamine/issues/536

- Made XLSX package path resolution more robust for non-standard package
  layouts. [Issue #638].

  [Issue #638]: https://github.com/tafia/calamine/issues/638

- Changed XLSX `<t>` text handling in shared strings and inline strings to trim
  leading and trailing ASCII whitespace (space, tab, CR, LF) unless the element
  carries `xml:space="preserve"`.  See [PR #671] and [PR #673].

  [PR #671]: https://github.com/tafia/calamine/pull/671
  [PR #673]: https://github.com/tafia/calamine/pull/673


### Fixed

- Fixed XLSX shared-formula cell-name replacement to be more precise for defined
  names. [PR #664].

  [PR #664]: https://github.com/tafia/calamine/pull/664

- Fixed XLSX custom number-format detection to treat the `*` (fill/repeat)
  operator as escaping the character that follows it. [PR #667].

  [PR #667]: https://github.com/tafia/calamine/pull/667

- Improved the XLS error message when a file is too small to be a valid
  workbook. [PR #670].

  [PR #670]: https://github.com/tafia/calamine/pull/670


## [0.35.0] - 2026-5-10

### Added

- Added `has_1904_epoch()` method to Xls/Xlsx/Xlsb structs to allow the user to
  determine which date epoch is in use by Excel. [PR #630].

  [PR #630]: https://github.com/tafia/calamine/pull/630

- Made `RowDeserializer` public to allow a custom `DeserializeSeed`.

  relation ids. Previously accepted only `r:` and `relationships:` prefixes.
  [Issue #634].

  [Issue #634]: https://github.com/tafia/calamine/issues/634

- Fixed XLSX issue where rich text `<r>` elements were ignored after initial
  plain `<t>` elements. [Issue #636].

  [Issue #636]: https://github.com/tafia/calamine/issues/636

- Fixed XLS issue where date format was ignored for formula values.
  [Issue #640].

  [Issue #640]: https://github.com/tafia/calamine/issues/640

- Fixed XLSX shared formula expansion corrupting function names. The
  `replace_cell_names()` function treated `LOG10` as a cell reference (column
  LOG, row 10). [Issue #644].

  [Issue #644]: https://github.com/tafia/calamine/issues/644

- Fixed XLSX `inlineStr` issue for elements that contain CDATA. [Issue #648].

  [Issue #648]: https://github.com/tafia/calamine/issues/648

- Fixed panic when parsing formulas in XLS BIFF5 workbooks.The `parse_formula`
  function decoded the non-3D PtgRef, PtgArea, PtgRefErr, and PtgAreaErr tokens
  assuming BIFF8 sizes. [PR #643].

  [PR #643]: https://github.com/tafia/calamine/pull/643

- Fixed XLS panic with unsupported formula functions. Handle unsupported XLS
  function ids as formula parse errors instead of indexing past the function
  table. [Issue #646].

  [Issue #646]: https://github.com/tafia/calamine/issues/646


## [0.34.0] - 2026-03-07

### Changed

  [PR #620]: https://github.com/tafia/calamine/pull/620

- Updated dependencies for release 0.34.0:

  - `quick-xml`: 0.38 -> 0.39. [PR #617]

  [PR #617]: https://github.com/tafia/calamine/pull/617

  [PR #606]: https://github.com/tafia/calamine/pull/606
  [PR #608]: https://github.com/tafia/calamine/pull/608
  [PR #609]: https://github.com/tafia/calamine/pull/609
  [PR #611]: https://github.com/tafia/calamine/pull/611

### Fixed

- Fixed capitalized workbook/book stream handling in XLS files. [PR #618].

  [PR #618]: https://github.com/tafia/calamine/pull/618

- Fixed issue where BIFF5 `Lbl` and `ExternSheet` records were incorrectly
  parsed as BIFF8. [PR #613].

  [PR #613]: https://github.com/tafia/calamine/pull/613

  [PR #619]: https://github.com/tafia/calamine/pull/619

- Fixed issue where XLSX cells with an empty `<v/>` value returned a string with
  index 0 instead of an Empty value. [Issue #607].

  [Issue #607]: https://github.com/tafia/calamine/issues/607

- Fixed millisecond rounding issue where 1000 milliseconds weren't rounded up to
  the next second. [Issue #602], [PR #605].

  [Issue #602]: https://github.com/tafia/calamine/issues/602
  [PR #605]: https://github.com/tafia/calamine/pull/605


## [0.33.0] - 2026-02-04

### Added

- Added support for reading data from Pivot Tables, which involves reading data
  from the internal Pivot Cache. [PR #559].

  [PR #559]: https://github.com/tafia/calamine/pull/559

### Changed

- Update dependencies for release 0.33.0:

  - `zip`: 4.2.0 -> 7.0.
  - `atoi_simd`: 0.16 -> 0.17

### Fixed

- Fixed potential memory exhaustion issue in ODS files that could be triggered
  via repeated empty rows/columns.

  The fix adds limits to prevent memory exhaustion from malicious ODS files that
  declare billions of repeated cells via `table:number-rows-repeated` and
  `table:number-columns`-repeated attributes.

  The change adds the following protection layers:

  - Add cap for columns per row at `MAX_COLUMNS` (16,384).
  - Add cap for total row repeats at `MAX_ROWS` (1,048,576).
  - Add cap for total cells at `MAX_CELLS` (100 million) in `get_range()`.

  These limits match XLSX's existing row/column limits and prevent a 7KB
  malicious file from attempting to allocate memory for 17+ billion cells.

  When MAX_CELLS is exceeded, return `OdsError::CellLimitExceeded` instead
  of silently returning an empty range. This ensures callers are properly
  informed of truncation rather than receiving silent data loss.

  [Issue #594], [PR #596].

  [Issue #594]: https://github.com/tafia/calamine/issues/594
  [PR #596]: https://github.com/tafia/calamine/pull/596

- Fixed an issue where XLSX files with tables that had the internal `insertRow`
  attribute set returned a `Dimensions` object where the end row was less than
  the start row. This caused an assert/panic when trying to create a `Range`
  object to return the table range. [Issue #589].

  [Issue #589]: https://github.com/tafia/calamine/issues/589

- Fixed an issue with XLSX files where worksheet tables used the unusual, but
  valid, absolute reference system like `"/xl/tables/table1.xml"` instead of the
  common Excel generated relative system `"../tables/table1.xml"`. [Issue #587].

  [Issue #587]: https://github.com/tafia/calamine/issues/587


## [0.32.0] - 2025-11-20

### Changed

- Refactored VBA reading functions to be on-demand for better performance.

- Simplified `vba_project()` function return type from `Option<Result<T>>` to
  `Result<Option<T>>` for more idiomatic error handling. This is a breaking
  change.

### Fixed

- Fixed out-of-memory vulnerabilities in XLS file parsing by bounding
  allocations.

- Fixed and extended support for XLSX shared formulas with handling of ranges,
  absolute references, and column/row ranges in XLSX files.

- Fixed XLSX issue with missing shared string sub-elements. Also improved error
  messages for shared string parsing issues.

- Fixed acceptance of XLS `XLUnicodeRichExtendedString` records without reserved
  tags.

- Fixed various edge cases in XLS handling that could lead to parsing errors.


## [0.31.0] - 2025-09-27

### Changed

- Upgraded `quick-xml` to v0.38. This was a significant change in `quick-xml`
  relative to v0.37 and required changes in `calamine` to entity handling. It
  also fixes EOL handling which may lead to regressions in `calamine`
  applications if they expected to see `"\r\n"` in strings instead of the
  correct (for XML and Excel) `"\n"`.

  For most users these will be inconsequential changes but please take note
  before upgrading production code.

- Renamed the `"dates"` feature flag to `"chrono"` since there is now some
  native date handling features without `"chrono"`. The `"chrono"` flag is more
  specific and accurate. The `"dates"` flag is still supported as before for
  backward compatibility.

  This change also made some datatype methods related to date/times available in
  the `"default"` feature set. They were previously hidden unnecessarily behind
  the "dates/"chrono" flag.

### Added

- Added a conversion function to `ExcelDateTime` to convert the inner serial
  Excel datetime to standard year, month, date, hour, minute, second and
  millisecond components. Works for 1900 and 1904 epochs.

### Fixed

- Fixed issue where Excel xlsx shared formula failed if it contained Unicode
  characters. [Issue #553].

  [Issue #553]: https://github.com/tafia/calamine/issues/553

- Fixed issue where Excel XML escapes in strings weren't unescaped. For example
  `"_x000D_" -> "\r"`. [Issue #469].

  [Issue #469]: https://github.com/tafia/calamine/issues/469


## [0.30.1] - 2025-09-06

### Added

- Added `Debug` and `Clone` to `Table` for easier debugging. [PR #547].

  [PR #547]: https://github.com/tafia/calamine/issues/547

### Fixed

- Fixed issue [Issue #548] for xls files where the `SST` record had an incorrect
  number of unique strings.

  [Issue #548]: https://github.com/tafia/calamine/issues/548


## [0.30.0] - 2025-08-07

### Changed

- Unpinned the `zip.rs` dependency from v4.2.0 to allow cargo to choose the
  correct version for the user's rustc version.

  The Rust MSRV was bumped to v1.75.0 (which it should have been for for
  `zip.rs` compatibility in previous releases).

  See the discussion at [Issue #527].

  [Issue #527]: https://github.com/tafia/calamine/issues/527


## [0.29.0] - 2025-07-17

### Added

- Add additional documentation and examples for the `Range`, `Cell`, `XlsxError`
  and `Table` structs, and `Xlsx` Table and Merge methods. Issue #459

### Changed

- Pin zip.rs to v4.2.0.

  The current latest release of `zip.rs`, v4.3.0, requires a MSRV of v1.85.0.
  This release pins `zip.rs` to v4.2.0 to allow users to maintain a MSRV of
  v1.73.0 for at least one more release. It is likely that `calamine` v0.30.0 or
  later will move back to the latest `zip.rs` v4.x and require rustc v1.85.0.

### Fixed

- Fixed issue where XLSX files had Windows style directory separators for
  internal paths instead of the required Unix style separators. Issue #530.
- Fixed several XLS parsing issues which could lead to out-of-memory errors. PR
  #525.
- Fixed numeric underflow in `Xlsx::from_sparse()` and also ensured that the
  associated `Range` of cells would be in row-column order. PR #524.
