Hello, MicroPython is an implementation of a subset of Python 3.5 which is optimised for systems with minimal resources, including microcontrollers and embedded/IoT systems. https://github.com/micropython/micropython Changes in this release include: py core: - use wrapper to check self argument of builtin methods, to prevent seg faults - catch case when relative import happens without active package - fix running package submodule with -m - add TimeoutError exception subclassed from OSError - prevent many extra vstr allocations by preallocating room for null byte - modbuiltins: Implement round() to precision - implement memoryview slice assignment, eg m1[0:3] = m2[2:5] - viper: allow functions to take up to 4 arguments - viper: issue an error when compiling functions with more than 4 args - raise SyntaxError when str hex escape sequence is malformed - fix handling of parsing empty input so it raises an exception - viper: compile errors now have traceback with function and filename - make list += accept all arguments and add test extmod: - ubinascii: add a2b_base64 and b2a_base64 functions - machine: implement physical memory access using /dev/mem (Linux, etc) lib: - readline: add emacs control chars for cursor movement (disabled by default) tools: - update upip to 0.5.4: recognize and handle "package not found" error unix port: - add O_WRONLY | O_CREAT to open call when opening file for append ("a") - socket.getaddrinfo: accept family & socktype arguments - socket.getaddrinfo: port is unsigned value - modsocket: implement sendto(), recvfrom(), inet_pton() - set MICROPY_PY_SYS_PLATFORM to "darwin" if compiled on OSX Detailed changelog: https://github.com/micropython/micropython/releases/tag/v1.4.5 -- Best regards, Paul mailto:pmiscml@gmail.com

Dear community, I'm pleased to announce the availability of python-rrdtool 0.1.2. It's a Python binding for rrdtool, the popular Round Robin Database. The binding are based on the original Python (2.x) binding by Hye-Shik Chang. It supports Python 2.6+ and 3.3+. Changes in version 0.1.2: * Added support for the xport command. * Added support for the lastupdate command. * On Python 2.x, str objects are now returned instead of unicode objects. * Improved documentation by adding latest options of rrdtool commands. * Merged some changes from upstream. The project is hosted on Github: https://github.com/commx/python-rrdtool Installation is easy using pip (replace with pip3 for Python 3): # pip install rrdtool Further documentation and usage examples can be found on the Github project page. I'd like to encourage users to test the binding and submit bugs to the issue tracker there. Thank you. -- Best regards, Christian Jurk

PyCA cryptography 1.0 released
by Paul Kehrer Aug. 12, 2015

Aug. 12, 2015

On behalf of all the contributors I am pleased to announce the release of PyCA/cryptography (https://github.com/pyca/cryptography) 1.0! cryptography is a package which provides cryptographic recipes and primitives to Python developers. Our goal is for it to be your "cryptographic standard library". We support Python 2.6-2.7, Python 3.3+, and PyPy. Changelog (https://cryptography.io/en/latest/changelog/): * Switched to the new cffi set_source out-of-line API mode for compilation. This results in significantly faster imports and lowered memory consumption. Due to this change we no longer support PyPy releases older than 2.6 nor do we support any released version of PyPy3 (until a version supporting cffi 1.0 comes out). * Fix parsing of OpenSSH public keys that have spaces in comments. * Support serialization of certificate signing requests using the public_bytes method of CertificateSigningRequest. * Support serialization of certificates using the public_bytes method of Certificate. * Add get_provisioning_uri method to HOTP and TOTP for generating provisioning URIs. * Add ConcatKDFHash and ConcatKDFHMAC. * Raise a TypeError when passing objects that are not text as the value to NameAttribute. * Add support for OtherName as a general name type. * Added new X.509 extension support in Certificate. The following new extensions are now supported: * OCSPNoCheck * InhibitAnyPolicy * IssuerAlternativeName * NameConstraints * Extension support was added to CertificateSigningRequest. * Add support for creating signed certificates with CertificateBuilder. This includes support for the following extensions: * BasicConstraints * SubjectAlternativeName * KeyUsage * ExtendedKeyUsage * SubjectKeyIdentifier * AuthorityKeyIdentifier * AuthorityInformationAccess * CRLDistributionPoints * InhibitAnyPolicy * IssuerAlternativeName * OCSPNoCheck * Add support for creating certificate signing requests with CertificateSigningRequestBuilder. This includes support for the same extensions supported in the CertificateBuilder. ...and numerous other small improvements! This release is the result of 670 commits from 213 different pull requests. These pull requests were created by 23 different contributors. -Paul Kehrer (reaperhulk)

It includes these enhancements and fixes: Driver Compatibility -------------------- MS SQL Server * Added a work-around for MS SQL Server Native Client to be able to support VARCHAR/VARBINARY(MAX) columns when using the Native Client with direct execution mode or Python type binding mode. Thanks to ZeOmega for reporting this. * Added new helper singleton BinaryNull to allow binding a NULL to a VARBINARY column with SQL Server in direct execution mode or Python type binding mode (as used for FreeTDS). Using the usual None doesn't work in those cases, since SQL Server does not accept a VARCHAR data type as input for VARBINARY, except by using an explicit "CAST(? AS VARBINARY)". mxODBC binds None as VARCHAR for best compatibility, when not getting any type hints from the ODBC driver. Misc: * The various __version__ attributes in mxODBC are now automatically updated during release. In the past, we sometimes missed updating a few places when cutting releases.

Sorry folks, minor hiccup for Python 3.5.0rc1
by Larry Hastings Aug. 11, 2015

Aug. 11, 2015

I built the source tarballs with a slightly-out-of-date tree. We slipped the release by a day to get two fixes in, but the tree I built from didn't have those two fixes. I yanked the tarballs off the release page as soon as I suspected something. I'm rebuilding the tarballs and the docs now. If you grabbed the tarball as soon as it appeared, it's slightly out of date, please re-grab. Sorry for the palaver, //arry/
