v.0.5.8

• Code refactoring and documentation, extra error handling;
• Added provision for SAVEPOINT support in documentation, chapter Transactions with SAVEPOINT

Now the library covers 99% of all usage cases. The only bit missing - support for cursors, which should only be used within SQL functions anyway.

v.0.5.7

• added exception handling for query notification;
• minor code re-factoring;

v.0.5.6

This version contains a major change to add support for nested transactions. It is not a breaking change, that's why only minor version increment was done, even though supporting nested transactions represents a major milestone for the library.

Chapter Nested Transactions was added to documentation with a code example.

Things still outstanding as far as the full PG support goes:

• Support for SAVEPOINT - not sure how this can fit into a promise chain at all, and who really needs it;
• Support for cursors - so few developers really use those, because they are mostly employed within function implementation, as a proper approach, not on the client side.

v.0.5.5

This update is just to close a few minor changes in documentation + minor code re-factoring before starting to work on a major change for 0.6.0. - nested transaction support.

v.0.5.4

Documentation updates, nothing else.

v.0.5.3

• Added method any() to each access protocol, for shortness and completeness;
• Added promise library Lie to the list of supported, though with reservation, since it has only catch(), but no done() and no finally()
• Minor code changes and documentation;

v.0.5.2

• removed verification for single-instance library verification as unnecessary;
• updated tests and documentation.
• introduced tests for the database, but didn't finish (commented out);

v.0.5.1

• Added better support for alternative promise libraries. Now we support: promise(default), bluebird, when and q.
• Added property options.query for better diagnostics;
• Many improvements in documentation, shifting focus toward generic promises support.

v.0.5.0

• Added options.pgFormatting to forward query formatting into PG;
• Added options.promiseLib, to override the default promise library used;
• Added many new tests for better coverage;
• A few minor bug fixes and code refactoring;
• Many updates in the documentation.

v.0.4.9

• Improved query formatting, with minor fixing;
• Improved test coverage;
• Documentation updates.
