- Issue #20538: UTF-7 incremental decoder produced inconsistant string when input was truncated in BASE64 section.
- Issue #20731: Properly position in source code files even if they are opened in text mode. Patch by Serhiy Storchaka.
- Issue #19619: str.encode, bytes.decode and bytearray.decode now use an internal API to throw LookupError for known non-text encodings, rather than attempting the encoding or decoding operation and then throwing a TypeError for an unexpected output type. (The latter mechanism remains in place for third party non-text encodings) Library:
- Issue #20778: Fix modulefinder to work with bytecode-only modules.
- Issue #20791: copy.copy() now doesn’t make a copy when the input is a bytes object. Initial patch by Peter Otten.

- Issue #20404: io.TextIOWrapper (and hence the open() builtin) now uses the internal codec marking system added for issue #19619 to throw LookupError for known non-text encodings at stream construction time. The existing output type checks remain in place to deal with unmarked third party codecs.

- Issue #20013: Some imap servers disconnect if the current mailbox is deleted, and imaplib did not handle that case gracefully. Now it handles the ‘bye’ correctly.
- Issue #19920: TarFile.list() no longer fails when outputs a listing containing non-encodable characters. Based on patch by Vajrasky Kok.

- Issue #8260: The read(), readline() and readlines() methods of codecs.StreamReader returned incomplete data when were called after readline() or read(size). Based on patch by Amaury Forgeot d’Arc IDLE:

- Issue #19920: Added tests for TarFile.list(). Based on patch by Vajrasky Kok.
