[Ludovic Rousseau]

Hello,

A new version of pcsc-lite 1.5.3 is available at [1].
This version fixes bugs. No new feature added.

Changelog:
pcsc-lite-1.5.3: Ludovic Rousseau
29 April 2009
- SCardEstablishContext(): check we do not reuse an already allocated
  hContext
  Thanks to Daniel Nobs for the bug report and patch
- pcsclite.h: add missing SCARD_E_* and SCARD_W_* return code. They are
  unused by pcsc-lite but defined on Windows
- reader.h: add PIN_PROPERTIES_STRUCTURE structure and
FEATURE_IFD_PIN_PROPERTIES
  Thanks to Martin Paljak for the patch
- remove powermgt_macosx.c since it is using APSL version 1.1 instead of
  the BSD-like licence like the other files
  Thanks to Stanislav Brabec for the bug report
- avoid a possible crash due to a race condition
  Thanks to Matheus Ribeiro for the patch
- change default log level from PCSC_LOG_INFO to PCSC_LOG_ERROR to limit
  syslog pollution
- CardDisconnect(): call RFUnlockAllSharing() instead of
  RFUnlockSharing() to release all nested locks. The problem occurs if
  SCardBeginTransaction() are made without corresponding
  SCardEndTransaction().  OpenSC "pkcs11-tool -I" exhibits such a
  behavior.
  Thanks to Marc Rios Valles for the bug report
- some other minor improvements and bug corrections
