• Backwards-incompatible: Rename TextBlobException to TextBlobError and MissingCorpusException to MissingCorpusError.
• Backwards-incompatible: Format classes are passed a file object rather than a file path.

0.8.4 (2014-02-02)

• Various improvements to spelling correction: preserves whitespace characters (Issue #12); handle contractions and punctuation between words. Thanks @davidnk.
• Make TextBlob.words more memory-efficient.
• Translator now sends POST instead of GET requests. This allows for larger bodies of text to be translated (Issue #49).
• Update pattern tagger for better accuracy.

0.8.1 (2013-11-16)

• Fix bug that caused ValueError upon sentence tokenization. This removes modifications made to the NLTK sentence tokenizer.
• Add Word.lemmatize() method that allows passing in a part-of-speech argument.
• Word.lemma returns correct part of speech for Word objects that have their pos attribute set. Thanks @RomanYankovsky.

0.8.0 (2013-10-23)

• Update pattern resources for improved parser accuracy.
• Update NLTK.
• Allow Translator to connect to proxy server.
• PerceptronTagger completely deprecated. Install the textblob-aptagger extension instead.

• Suppress warning about not having scikit-learn installed.

0.7.0 (2013-09-25)

• Wordnet integration. Word objects have synsets and definitions properties. The text.wordnet module allows you to create Synset and Lemma objects directly.
• Move all English-specific code to its own module, text.en.
• Basic extensions framework in place. TextBlob has been refactored to make it easier to develop extensions.
• Add text.classifiers.PositiveNaiveBayesClassifier.
• Update NLTK.
• NLTKTagger now working on Python 3.
• Fix __str__ behavior. print(blob) should now print non-ascii text correctly in both Python 2 and 3.
• Backwards-incompatible: All abstract base classes have been moved to the text.base module.
• Backwards-incompatible: PerceptronTagger will now be maintained as an extension, textblob-aptagger. Instantiating a text.taggers.PerceptronTagger() will raise a DeprecationWarning.

0.6.3 (2013-09-15)

• Word tokenization fix: Words that stem from a contraction will still have an apostrophe, e.g. "Let's" => ["Let", "'s"].
• Fix bug with comparing blobs to strings.
• Add text.taggers.PerceptronTagger, a fast and accurate POS tagger. Thanks @syllog1sm.
• Note for Python 3 users: You may need to update your corpora, since NLTK master has reorganized its corpus system. Just run curl https://raw.github.com/sloria/TextBlob/master/download_corpora.py | python again.
• Add download_corpora_lite.py script for getting the minimum corpora requirements for TextBlob's basic features.

0.6.2 (2013-09-05)

• Fix bug that resulted in a UnicodeEncodeError when tagging text with non-ascii characters.
• Add DecisionTreeClassifier.
• Add labels() and train() methods to classifiers.

0.6.1 (2013-09-01)

• Classifiers can be trained and tested on CSV, JSON, or TSV data.
• Add basic WordNet lemmatization via the Word.lemma property.
• WordList.pluralize() and WordList.singularize() methods return WordList objects.

0.6.0 (2013-08-25)

• Add Naive Bayes classification. New text.classifiers module, TextBlob.classify(), and Sentence.classify() methods.
• Add parsing functionality via the TextBlob.parse() method. The text.parsers module currently has one implementation (PatternParser).
• Add spelling correction. This includes the TextBlob.correct() and Word.spellcheck() methods.
• Update NLTK.
• Backwards incompatible: clean_html has been deprecated, just as it has in NLTK. Use Beautiful Soup's soup.get_text() method for HTML-cleaning instead.
• Slight API change to language translation: if from_lang isn't specified, attempts to detect the language.
• Add itokenize() method to tokenizers that returns a generator instead of a list of tokens.

0.5.3 (2013-08-21)

• Unicode fixes: This fixes a bug that sometimes raised a UnicodeEncodeError upon creating accessing sentences for TextBlobs with non-ascii characters.
• Update NLTK

0.5.2 (2013-08-14)

• Important patch update for NLTK users: Fix bug with importing TextBlob if local NLTK is installed.
• Fix bug with computing start and end indices of sentences.

0.5.1 (2013-08-13)

• Fix bug that disallowed display of non-ascii characters in the Python REPL.
• Backwards incompatible: Restore blob.json property for backwards compatibility with textblob<=0.3.10. Add a to_json() method that takes the same arguments as json.dumps.
• Add WordList.append and WordList.extend methods that append Word objects.

0.5.0 (2013-08-10)

• Language translation and detection API!
• Add text.sentiments module. Contains the PatternAnalyzer (default implementation) as well as a NaiveBayesAnalyzer.

0.4.0 (2013-08-05)

• New text.tokenizers module with WordTokenizer and SentenceTokenizer. Tokenizer instances (from either textblob itself or NLTK) can be passed to TextBlob's constructor. Tokens are accessed through the new tokens property.
• New Blobber class for creating TextBlobs that share the same tagger, tokenizer, and np_extractor.
• Add ngrams method.
• Backwards-incompatible: TextBlob.json() is now a method, not a property. This allows you to pass arguments (the same that you would pass to json.dumps()).
• New home for documentation: https://textblob.readthedocs.io/
• Add parameter for cleaning HTML markup from text.
• Minor improvement to word tokenization.
• Updated NLTK.
• Fix bug with adding blobs to bytestrings.

0.3.10 (2013-08-02)

• Added instructions to install textblob without nltk bundled.
• Dropping official 3.1 and 3.2 support.

0.3.8 (2013-07-30)

• Importing TextBlob is now much faster. This is because the noun phrase parsers are trained only on the first call to noun_phrases (instead of training them every time you import TextBlob).
• Add text.taggers module which allows user to change which POS tagger implementation to use. Currently supports PatternTagger and NLTKTagger (NLTKTagger only works with Python 2).
• NPExtractor and Tagger objects can be passed to TextBlob's constructor.
• Fix bug with POS-tagger not tagging one-letter words.
• Rename text/np_extractor.py -> text/np_extractors.py
• Add run_tests.py script.

0.3.7 (2013-07-28)

• Every word in a Blob or Sentence is a Word instance which has methods for inflection, e.g word.pluralize() and word.singularize().
• Updated the np_extractor module. Now has an new implementation, ConllExtractor that uses the Conll2000 chunking corpus. Only works on Py2.
