• Fix inflection of a few irregular English nouns. Thanks jonmcoe.

Bug fixes:

• Fix DecisionTreeClassifier.pprint for compatibility with nltk>=3.0.2.

• Fix bug that raised a SyntaxError when translating text with non-ascii characters on Python 3.

• Fix bug that showed "double-escaped" unicode characters in translator output (issue #56). Thanks Evan Dempsey.

• Backwards-incompatible: Completely remove import text.blob. You should import textblob instead.

• Backwards-incompatible: Completely remove PerceptronTagger. Install textblob-aptagger instead.

• Backwards-incompatible: Rename TextBlobException to TextBlobError and MissingCorpusException to MissingCorpusError.

• Backwards-incompatible: Format classes are passed a file object rather than a file path.

• Backwards-incompatible: If training a classifier with data from a file, you must pass a file object (rather than a file path).

• Updated English sentiment corpus.

• Add feature_extractor parameter to NaiveBayesAnalyzer.

• Add textblob.formats.get_registry() and textblob.formats.register() which allows users to register custom data source formats.

• Change BaseClassifier.detect from a staticmethod to a classmethod.

• Improved docs.

• Tested on Python 3.4.

• Fix display (__repr__) of WordList slices on Python 3.

• Add download_corpora module. Corpora must now be downloaded using python -m textblob.download_corpora.

• Memory usage improvements to NaiveBayesAnalyzer and basic_extractor (default feature extractor for classifiers module).

• Add textblob.tokenizers.sent_tokenize and textblob.tokenizers.word_tokenize convenience functions.

• Add textblob.classifiers.MaxEntClassifer.

• Improved NLTKTagger.

• Fix bug in spelling correction that stripped some punctuation (Issue #48).

• 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.

• 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.

• Backwards-incompatible: Renamed package to textblob. This avoids clashes with other namespaces called text. TextBlob should now be imported with from textblob import TextBlob.

• 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.

• Bugfix updates.

• Fix bug in feature extraction for NaiveBayesClassifier.

• Fix repr output when a TextBlob contains non-ascii characters.

• Fix part-of-speech tagging with PatternTagger on Windows.

• Suppress warning about not having scikit-learn installed.

• 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.

• 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.

• Fix bug that resulted in a UnicodeEncodeError when tagging text with non-ascii characters.

• Add DecisionTreeClassifier.

• Add labels() and train() methods to classifiers.

• 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.

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

• Update NLTK

• 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.

• 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.

• Language translation and detection API!

• Add text.sentiments module. Contains the PatternAnalyzer (default implementation) as well as a NaiveBayesAnalyzer.

• Part-of-speech tags can be accessed via TextBlob.tags or TextBlob.pos_tags.

• Add polarity and subjectivity helper properties.

• 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.

• Bundled NLTK no longer overrides local installation.

• Fix sentiment analysis of text with non-ascii characters.

• Updated nltk.

• ConllExtractor is now Python 3-compatible.

• Improved sentiment analysis.

• Blobs are equal (with ==) to their string counterparts.

• Added instructions to install textblob without nltk bundled.

• Dropping official 3.1 and 3.2 support.

• 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.

• 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.
