- Upgrade `pdfminer.six` from `20200517` to `20211012`; see [that library's changelog](https://github.com/pdfminer/pdfminer.six/blob/develop/CHANGELOG.md) for details, but a key difference is an improvement in how it assigns `line`, `rect`, and `curve` objects. (Diagonal two-point lines, for instance, are now `line` objects instead of `curve` objects.)
- Change behavior of horizontal `text_strategy`, so that it uses the top and bottom of *every* word, not just the top of every word and the bottom of the last. ([#467](https://github.com/jsvine/pdfplumber/pull/467) + [#466](https://github.com/jsvine/pdfplumber/issues/466) + [#265](https://github.com/jsvine/pdfplumber/issues/265)) [h/t @bobluda + @samkit-jain]
- Fix slowdown in `.extract_words(...)`/`WordExtractor.iter_chars_to_words(...)` on very long words, caused by repeatedly re-calculating bounding box. ([#483](https://github.com/jsvine/pdfplumber/discussions/483))
- Add `--laparams` flag to CLI. ([#407](https://github.com/jsvine/pdfplumber/pull/407))
### Changed
- Change `.convert_csv(...)` to order objects first by page number, rather than object type. ([#407](https://github.com/jsvine/pdfplumber/pull/407))
- Change `.convert_csv(...)`, `.convert_json(...)`, and CLI so that, by default, they returning all available object types, rather than those in a predefined default list. ([#407](https://github.com/jsvine/pdfplumber/pull/407))
- Fix `.extract_text(...)` so that it can accept generator objects as its main parameter. ([#385](https://github.com/jsvine/pdfplumber/pull/385)) [h/t @alexreg]
- Fix page-parsing so that `LTAnno` objects (which have no bounding-box coordinates) are not extracted. (Was only an issue when setting `laparams`.) ([#388](https://github.com/jsvine/pdfplumber/issues/383))
- Reinstate access to higher-level layout objects (such as `textboxhorizontal`) when `laparams` is passed to `pdfplumber.open(...)`. Had been removed in `0.5.24` via [1f87898](https://github.com/jsvine/pdfplumber/commit/1f878988576017b64f5cd77e1eb21b401124c699). ([#359](https://github.com/jsvine/pdfplumber/issues/359) + [#364](https://github.com/jsvine/pdfplumber/pull/364))
- Add `Page.close/__enter__/__exit__` methods, by generalizing that behavior through the `Container` class ([b1849f4](https://github.com/jsvine/pdfplumber/commit/b1849f4))
- Change `TableFinder` to return tables in order of topmost-and-then-leftmost, rather than leftmost-and-then-topmost ([#336](https://github.com/jsvine/pdfplumber/issues/336))
- Explicitly load text as utf-8 in `setup.py` ([7854328](https://github.com/jsvine/pdfplumber/commit/7854328)) ([#304](https://github.com/jsvine/pdfplumber/issues/304))
- Fix `pdfplumber.open(...)` so that it does not close file objects passed to it ([408605f](https://github.com/jsvine/pdfplumber/commit/408605f)) ([#312](https://github.com/jsvine/pdfplumber/issues/312))
- Change character attribute `upright` from `int` to `bool` (per original `pdfminer.six` representation) ([1f87898](https://github.com/jsvine/pdfplumber/commit/1f87898))
- Remove access and reference to `Container.figures`, given that they are not fundamental objects ([8e74cb9](https://github.com/jsvine/pdfplumber/commit/8e74cb9))
- Refactor/simplify `Page.process_objects` ([1f87898](https://github.com/jsvine/pdfplumber/commit/1f87898)), `utils.extract_words` ([c8b200e](https://github.com/jsvine/pdfplumber/commit/c8b200e)), and `convert.serialize` ([a74d3bc](https://github.com/jsvine/pdfplumber/commit/a74d3bc))
- Remove `test_issues.py:test_pr_77` ([917467a](https://github.com/jsvine/pdfplumber/commit/917467a)) and narrow `test_ca_warn_report:test_objects` ([6233bbd](https://github.com/jsvine/pdfplumber/commit/6233bbd)) to speed up tests
- Add `page.annots` and `page.hyperlinks`, replacing non-functional `page.annos`, and mirroring pdfminer's language ("annot" vs. "anno"). ([aa03961](https://github.com/jsvine/pdfplumber/commit/aa03961))
- Add `page/pdf.to_json` and `page/pdf.to_csv` ([cbc91c6](https://github.com/jsvine/pdfplumber/commit/cbc91c6))
- Add `relative=True/False` parameter to `.crop` and `.within_bbox`; those methods also now raise exceptions for invalid and out-of-page bounding boxes. ([047ad34](https://github.com/jsvine/pdfplumber/commit/047ad34)) [h/t @samkit-jain]
- Remove `pdfminer.from_path` and `pdfminer.load` as deprecated; now `pdfminer.open` is the canonical way to load a PDF. ([00e789b](https://github.com/jsvine/pdfplumber/commit/00e789b))
- Simplify the logic in "text" table-finding strategies; in edge cases, may result in changes to results. ([d224202](https://github.com/jsvine/pdfplumber/commit/d224202))
- Drop support for Python 3.5 ([baf1033](https://github.com/jsvine/pdfplumber/commit/baf1033))
- Fix `.extract_words`, which had been returning incorrect results when `horizontal_ltr = False` ([d16aa13](https://github.com/jsvine/pdfplumber/commit/d16aa13))
- Fix `utils.resize_object`, which had been failing in various permutations ([d16aa13](https://github.com/jsvine/pdfplumber/commit/d16aa13))
- Fix `lines_strict` table-finding strategy, which a typo had prevented from being usable ([f0c9b85](https://github.com/jsvine/pdfplumber/commit/f0c9b85))
- Fix `utils.resolve_all` to guard against two known sources of infinite recursion ([cbc91c6](https://github.com/jsvine/pdfplumber/commit/cbc91c6))
- Fix `Page.extract_table(...)` to return `None` instead of crashing when no table is found ([d64afa8](https://github.com/jsvine/pdfplumber/commit/d64afa8)) [h/t @stucka]
- Allow `rect` and `curve` objects also to be passed to "explicit_..._lines" setting when table-finding. (And disallow other types of dicts to be passed.)
### Fixed
- Fix `utils.extract_text` bug introduced in prior version
- Fix and simplify obj-in-bbox logic (see commit [25672961](https://github.com/jsvine/pdfplumber/commit/25672961))
- Improve/fix the way `utils.extract_text` handles vertical text (see commit [8a5d858b](https://github.com/jsvine/pdfplumber/commit/8a5d858b)) [h/t @dwalton76]
- Have `Page.to_image` use bytes stream instead of file path (Issue [#124](https://github.com/jsvine/pdfplumber/issues/124) / PR [#179](https://github.com/jsvine/pdfplumber/pull/179)) [h/t @cheungpat]
- Fix issue [#176](https://github.com/jsvine/pdfplumber/issues/176), in which `Page.extract_tables` did not pass kwargs to `Table.extract` [h/t @jsfenfen]
- Visual debugging features, via `Page.to_image(...)` and `PageImage`. (Introduces `wand` and `pillow` as package requirements.)
- More powerful options for extracting data from tables. See changes below.
### Changed
- Entirely overhaul the table-extraction methods. Now based on [Anssi Nurminen's master's thesis](http://dspace.cc.tut.fi/dpub/bitstream/handle/123456789/21520/Nurminen.pdf?sequence=3).
- Disentangle `.crop` from `.intersects_bbox` and `.within_bbox`.
- Change default `x_tolerance` and `y_tolerance` for word extraction from `5` to `3`
### Fixed
- Fix bug stemming from non-decimalized page heights. [h/t @jsfenfen]
## [0.4.6] - 2017-01-26
### Added
- Provide access to `Page.page_number`
### Changed
- Use `.page_number` instead of `.page_id` as primary identifier. [h/t @jsfenfen]
- Change default `x_tolerance` and `y_tolerance` for word extraction from `0` to `5`
### Fixed
- Provide proper support for rotated pages
## [0.4.5] - 2016-12-09
### Fixed
- Fix bug stemming from when metadata includes a PostScript literal. [h/t @boblannon]
