Pdfplumber

Fixed
- Fix regression (introduced in `0.5.26`/[b1849f4](https://github.com/jsvine/pdfplumber/commit/b1849f4)) in closing files opened by `PDF.open`
- 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))

Development Changes
- Add a `python setup.py build sdist` test to main GitHub action. ([365](https://github.com/jsvine/pdfplumber/pull/365))

Added
- Add `Page.close/__enter__/__exit__` methods, by generalizing that behavior through the `Container` class ([b1849f4](https://github.com/jsvine/pdfplumber/commit/b1849f4))

Changed
- Change handling of floating point numbers; no longer convert them to `Decimal` objects and do not round them
- 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))
- Change `Page.to_image()`'s handling of alpha layer, to remove aliasing artifacts ([340](https://github.com/jsvine/pdfplumber/pull/340)) [h/t arlyon]

Development Changes

- Enforce `psf/black` and `flake8` on `tests/` ([327](https://github.com/jsvine/pdfplumber/pull/327)

Added

- 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))

Added
- Added `extra_attrs=[...]` parameter to `.extract_text(...)` ([c8b200e](https://github.com/jsvine/pdfplumber/commit/c8b200e)) ([#28](https://github.com/jsvine/pdfplumber/issues/28))
- Added `utils/page.dedupe_chars(...)` ([04fd56a](https://github.com/jsvine/pdfplumber/commit/04fd56a) + [b132d45](https://github.com/jsvine/pdfplumber/commit/b132d45)) ([#71](https://github.com/jsvine/pdfplumber/issues/71))

Changed

Development Changes

- 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

Added
- Add `utils.resolve` (non-recursive .resolve_all) ([7a90630](https://github.com/jsvine/pdfplumber/commit/7a90630))
- 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))

Changed
- 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 `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))
