**Full Changelog**: https://github.com/sciunto-org/python-bibtexparser/compare/v2.0.0b5...v2.0.0b6

**Minor Changes**

- Optionally raise an exception when adding duplicate blocks (425 by MiWeiss, reported by claell )

**Fixes**

- Fix bug in `von`-part name parsing (423 by mlutze)
- Fix duplicate entry replacement bugs (424 by MiWeiss, reported by claell )
- Fix problem with `__version__` (430 by MiWeiss , reported by mestia and a-detiste)
- Fix installation documentation (419 by mlutze )

Breaking Changes

- We do not assume anymore that blocks have to start at a new line (416 by zepinglee and benlogan)

**Attention:** While this means that we will also parse blocks starting anywhere else (e.g. on the same line where another block ended), this also has some side effects:

- Parsing of a block is aborted if a sequence which looks like a block start (e.g. `entry{`) is found anywhere within that block in addition to its head. This is done on purpose, to allow parsing of faulty files, but may have negative impacts in the few cases where a `entry{` (or similar) are genuinely part of a correct block.
- Commenting entire blocks with leading `%`, `` , or any other char sequence at the beginning of every line will not work anymore. This was never fully supported anyways, and still waits for its implementation. See 372 .

Other changes

- Addition external link in docs (408 by MiWeiss)

This is the first pre-release of `v2` (a complete library-rewrite) shipped to pypi. From previous feedback, it is stable enough to be used in most projects, but please proceed with caution and provide feedback if you identify problems:

Breaking Changes
===============
- Literally everything ;-) The API completely changed. Please see the migration guide in the docs: https://bibtexparser.readthedocs.io/en/main/migrate.html
- Some functionality, especially previous modules of the customization package have not yet been integrated in `v2` as their use-case is not obvious or newer and better alternatives have emerged.
- This is now permissively MIT licensed, without any GPL parts remaining.
- The documentation has been extended.


Why all that? Here's the advantages:
==============================
🚀 Order of magnitudes faster
🔧 Easily customizable parsing and writing
🌿 Access to raw, unparsed bibtex.
💩 Fault-Tolerant: Able to parse files with syntax errors
🀄 Massively simplified, robuster handling of de- and encoding (special chars, ...).
©️ Permissive MIT license

This release contains a range of frequently requested changes, including:
- Set `align_values` to an int or bool to fix min alignment in writing (316 by michaelfruth)
- Fix some docstrings (330 by CodePurble , 325 by MiWeiss)
- `customization.getnames`: respect protected names: (334 by tdegeus)
- No dict caching in bibdatabase (348 by MiWeiss). This makes the library slightly slower in some cases, but fixes previously wrong caching.


Edit: Due to a mistake, this tag was previously, for a couple of hours, on the wrong commit. This has now been fixed, i.e., the tag has been removed and correctly set again.
