## 1.2.3

- Moved to BitBucket.
- Allowed `formencode.validators.UnicodeString` to use different encoding of input and output, or no encoding/decoding at all.
- Fixes #2666139 DateValidator bug happening only in March under Windows in Germany :)
- Don’t let `formencode.compound.Any` shortcut validation when it gets an empty value (this same change had already been made to `formencode.compound.All`).
- Really updated German translation
- Fixes #2799713 force_defaults=False and <select> fields (regarding `formencode.htmlfill.render()`) Thanks to w31rd0 for the bug report and patch to fix it.

## 1.2.2

- Added keyword argument `force_defaults` to `formencode.htmlfill.render()`; when this is True (the default) this will uncheck checkboxes, unselect select boxes, etc., when a value is missing from the default dictionary.
- Updated German translation

## 1.2.1

- Be more careful about `unicode(Invalid(...))`, to make sure it always returns unicode.
- Fix broken `formencode.national` zip code validators.
- In `formencode.national` only warn about the pycountry or TG requirement when creating validators that require them.
- Fix another `formencode.htmlfill` error due to a field with no explicit value.

## 1.2

- Added `formencode.validators.IPAddress`, validating IP addresses, from Leandro Lucarella.
- Added `formencode.api.Invalid.__unicode__()`
- In `formencode.htmlfill` use a default encoding of utf8 when handling mixed `str`/`unicode` content. Also do not modify `<input type="image">` tags (previously `src` would be overwritten, for no good reason).
- In `formencode.validators.Email` allow single-character domain names (like x.com).
- Make `formencode.validators.FieldsMatch` give a normal `Invalid` exception if you pass it a non-dictionary. Also treat all missing keys as the empty string (previously the first key was required and would raise KeyError).
- `formencode.validators.Number` works with `inf` float values (before it would raise a OverflowError).
- The `tw` locale has been renamed to the more standard `zh_TW`.
- Added Japanese and Turkish translations.
- Fixed some outdated translations and errors in Spanish and Greek translations. Translations now managed with Babel.

## 1.1

- Fixed the `is_empty()` method in `formencode.validators.FieldStorageUploadConverter`; previously it returned the opposite of the intended result.
- Added a parameter to `htmlfill.render()`: `prefix_error`. If this parameter is true (the default) then errors automatically go before the input field; if false then they go after the input field.
- Remove deprecated modules: `fields`, `formgen`, `htmlform`, `sqlformgen`, and `sqlschema`.
- Added `formencode.htmlrename`, which renames HTML inputs.
- In `formencode.htmlfill`, non-string values are compared usefully (e.g., a select box with integer values).
- The validators `Int` and `Number` both take min/max arguments (from Shannon Behrens).
- Validators based on `formencode.validators.FormValidator` will not treat `{}` as an empty (unvalidated) value.
- Some adjustments to the URL validator.
- `formencode.compound.All` does not handle empty values, instead relying on sub-validators to check for emptiness.
- Fixed the `if_missing` attribute in `formencode.foreach.ForEach`; previously it would be the same list instance, so if you modified it then it would effect future `if_missing` values (reported by Felix Schwarz).
- Added formatter to `formencode.htmlfill`, so you can use `<form:error name="field_name" formatter="ignore" />` – this will cause the error to be swallowed, not shown to the user.
- Added `formencode.validators.XRI` for validation i-names, i-numbers, URLs, etc (as used in OpenID).
- Look in `/usr/share/locale` for locale files, in addition to the normal locations.
- Quiet Python 2.6 deprecation warnings.
- Fix `formencode.validators.URL`, which was accepting illegal characters (like newlines) and did not accept http://domain:PORT/

## 1.0.1

- `chained_validators` were removed from Schema somehow; now replaced and working.
- Put in missing `htmlfill.render(error_class=...)` parameter (was documented and implemented, but `render()` did not pass it through).

## 1.0

- Added `formencode.schema.SimpleFormValidator`, which wraps a simple function to make it a validator.
- Changed the use of `chained_validators` in Schemas, so that all chained validators get run even when there are previous errors (to detect all the errors).
- While something like `Int.to_python()` worked, other methods like `Int.message(...)` didn’t work. Now it does.
- Added Italian, Finnish, and Norwegian translations.

## 0.9

### Backward incompatible changes

- The notion of “empty” has changed to include empty lists, dictionaries, and tuples. If you get one of these values passed into (or generated by) a validator with `not_empty=True` you can get exceptions where you didn’t previously.

### Enhancements

- Added support for Paste’s MultiDict dictionary as input to Schema.to_python, by converting it to a normal dict via MultiDict.mixed. Previously MultiDicts wouldn’t work with CompoundValidators (like ForEach)
- Added encoding parameter to htmlfill, which will handle cases when mixed str and unicode objects are used (turning all str objects into unicode)
- Include `formencode.validators.InternationalPhoneNumber` from W-Mark Kubacki.
- `validators.Int` takes `min` and `max` options (from Felix Schwarz).
- You can control the missing message (which by default is just “Missing Value”) using the message `"missing"` in a validator (also from James Gardner).
- Added `validators.CADR` (for IP addresses with an optional range) and `validators.MACAddress` (from Christoph Haas).

### Bug Fixes

- Be friendlier when loaded from a zip file (as with py2exe); previously only egg zip files would work.
- Fixed bug in htmlfill when a document ends with no trailing text after the last tag.
- Fix problem with HTMLParser’s default unescaping routing, which only understood a very limited number of entities in attribute values.
- Fix problem with looking up A records for email addresses.
- `validators.String` now always returns strings. It also converts lists to comma-separated strings (no `[...]`), and can encode unicode if an `encoding` parameter is given. Empty values are handled better.
- `validators.UnicodeString` properly handles non-Unicode inputs.
- Make `validators.DateConverter` serialize dates properly (from James Gardner).
- Minor fix to setup.py to make FormEncode more friendly with zc.buildout.

## 0.7.1

- Set `if_missing=()` on `validators.Set`, as a missing value usually means empty for this value.
- Fix for `Email` validator that searches A records in addition to MX records (from Jacob Smullyan).
- Fixes for the `es` locale.

## 0.7

- Backward compatibility issue: Due to the addition of i18n (internationalization) to FormEncode, Invalid exceptions now have unicode messages. You may encounter unicode-related errors if you are mixing these messages with non-ASCII `str` strings.
- gettext-enabled branch merged in
- Fixes #1457145: Fails on URLs with port numbers
- Fixes #1559918 Schema fails to accept unicode errors
- `from formencode.validators import *` will import the `Invalid` exception now.
- `Invalid().unpack_errors(encode_variables=True)` now filters out None values (which `ForEach` can produce even for keys with no errors).

## 0.6

- `String(min=1)` implies `not_empty` (which seems more intuitive)
- Added `list_char` and `dict_char` arguments to `Invalid.unpack_errors` (passed through to `variable_encode`)
- Added a `use_datetime` option to `TimeValidator`, which will cause it to use `datetime.time` objects instead of tuples. It was previously able to consume but not produce these objects.
- Added `<form:iferror name="not field_name">` when you want to include text only when a field has no errors.
- There was a problem installing 0.5.1 on Windows with Python 2.5, now resolved.

## 0.5.1

- Fixed compound validators and `not_empty` (was breaking SQLObject’s PickleCol)

## 0.5

- Added `htmlfill.default_formatter_dict`, and you can poke new formatters in there to effective register them.
- Added an `escapenl` formatter (nl=newline) that escapes HTML and turns newlines into `<br>`.
- When `not_empty=False`, empty is assumed to be allowed. Thus `Int().to_python(None)` will now return `None`.

## 0.4

- Fixed up all the documentation.
- Validator `__doc__` attributes will include some automatically-appended information about all the message strings that validator uses.
- Deprecated `formencode.htmlform` module, because it is dumb.
- Added an `.all_messages()` method to all validators, primarily intended to be used for documentation purposes.
- Changed preferred name of `StringBoolean` to `StringBool` (to go with `bool` and `validators.Bool`). Old alias still available.
- Added `today_or_after` option to `validators.DateValidator`.
- Added a `validators.FileUploadKeeper` validator for helping with file uploads in failed forms. It still requires some annoying fiddling to make work, though, since file upload fields are so weird.
- Added `text_as_default` option to htmlfill. This treats all `<input type="something-weird">` elements as text fields. WHAT-WG adds weird input types, which can usually be usefully treated as text fields.
- Make all validators accept empty values if `not_empty` is False (the default). “Empty” means `""` or `None`, and will generally be converted None.
- Added `accept_python` boolean to all `FancyValidator` validators (which is most validators). This is a fixed version of the broken `validate_python` boolean added in 0.3. Also, it defaults to true, which means that all validators will not validate during `.from_python()` calls by default.
- Added `htmlfill.render(form, defaults, errors)` for easier rendering of forms.
- Errors automatically inserted by `htmlfill` will go at the top of the form if there’s no field associated with the error (raised an error in 0.3).
- Added `formencode.sqlschema` for wrapping SQLObject classes/instances. See the docstring for more.
- Added `ignore_key_missing` to `Schema` objects, which ignore missing keys (where fields are present) when no `if_missing` is provided for the field.
- Renamed `validators.StateProvince.extraStates` to `extra_states`, to normalize style.

### Bugfixes

- When checking destinations, `validators.URL` now allows redirect codes, and catches socket errors and turns them into proper errors.
- Fix typo in `htmlfill`
- Made URL and email regular expressions a little more lax/correct.
- A bunch of fixes to `validators.SignedString`, which apparently was completely broken.

## 0.3

- Allow errors to be inserted automatically into a form when using `formencode.htmlfill`, when a `<form:error>` tag isn’t found for an error.
- Added `if_key_missing` attribute to `schema.Schema`, which will fill in any keys that are missing and pass them to the validator.
- `FancyValidator` has changed, adding `if_invalid_python` and `validate_python` options (which also apply to all subclasses). Also `if_empty` only applies to `to_python` conversions.
- `FancyValidator` now has a `strip` option, which if true and if input is a string, will strip whitespace from the string.
- Allow chained validators to validate otherwise-invalid forms, if they define a `validate_partial` method. The credit card validator does this.
- Handle `FieldStorage` input (from file uploads); added a `formencode.fieldstorage` module to wrap those instances in something a bit nicer. Added `validators.FieldStorageUploadConverter` to make this conversion.
- Added `StringBoolean` converter, which converts strings like `"true"` to Python booleans.

### Bugfixes

- A couple fixes to `DateConverter`, `FieldsMatch`, `StringBoolean`, `CreditCardValidator`.
- Added missing `Validator.assert_string` method.
- `formencode.htmlfill_schemabuilder` handles checkboxes better.
- Be a little more careful about how `Invalid` exceptions are created (catch some errors sooner).
- Improved handling of non-string input in `htmlfill`.

### Experiments

- Some experimental work in `formencode.formgen`. Experimental, I say!
- Added an experimental `formencode.context` module for dynamically-scoped variables.
