DecodeSliceError::OutputSliceTooSmall is now conservative rather than precise. That is, the error will only occur if the decoded output cannot fit, meaning that Engine::decode_slice can now be used with exactly-sized output slices. As part of this, Engine::internal_decode now returns DecodeSliceError instead of DecodeError, but that is not expected to affect any external callers.
DecodeError::InvalidLength now refers specifically to the number of valid symbols being invalid (i.e. len % 4 == 1), rather than just the number of input bytes. This avoids confusing scenarios when based on interpretation you could make a case for either InvalidLength or InvalidByte being appropriate.

The short-lived 0.20 functions were the 0.13 functions with config replaced with engine.
Padding
If applicable, use the preset engines engine::STANDARD, engine::STANDARD_NO_PAD, engine::URL_SAFE,
or engine::URL_SAFE_NO_PAD.
The NO_PAD ones require that padding is absent when decoding, and the others require that
canonical padding is present .
If you need the < 0.20 behavior that did not care about padding, or want to recreate < 0.20.0's predefined Configs
precisely, see the following table.
Decoding can now either ignore padding, require correct padding, or require no padding. The default is to require
correct padding.
The NO_PAD config now requires that padding be absent when decoding.
0.20.0-alpha.1
Breaking changes
Extended the Config concept into the Engine abstraction, allowing the user to pick different encoding / decoding
implementations.
What was formerly the only algorithm is now the FastPortable engine, so named because it's portable (works on
any CPU) and relatively fast.
This opens the door to a portable constant-time
implementation (#153,
presumably ConstantTimePortable?) for security-sensitive applications that need side-channel resistance, and
CPU-specific SIMD implementations for more speed.
Standard base64 per the RFC is available via DEFAULT_ENGINE. To use different alphabets or other settings (
padding, etc), create your own engine instance.
CharacterSet is now Alphabet (per the RFC), and allows creating custom alphabets. The corresponding tables that
were previously code-generated are now built dynamically.
Since there are already multiple breaking changes, various functions are renamed to be more consistent and
discoverable.
MSRV is now 1.47.0 to allow various things to use const fn.
DecoderReader now owns its inner reader, and can expose it via into_inner(). For symmetry, EncoderWriter can do
the same with its writer.
encoded_len is now public so you can size encode buffers precisely.
